equipment must be the same circuit type.
•
Bolt the AMPS80 HP system securely to the floor.
•
Always assume electrical connections and/or conductors are live.
•
Turn off all circuit breakers and double-check potentially charged components with a voltmeter before
performing installation or maintenance.
•
Before installation, verify that the input voltage and current requirements of the load are within the specifications of the power system. Refer to the product nameplate label.
•
Keep tools away from walk areas to prevent personnel from tripping over the tools.
•
Wear safety glasses when working under any conditions that may be hazardous to your eyes.
•
Do not work on the power system, or connect or disconnect cables, during atmospheric lightning activity.
•
Do not let water enter the enclosure as this can cause electrical shorts, shocks, or electrocutions.
•
Do not remove the covers of electrical components as this can cause electrical shorts, shocks or electrocutions. There are no user serviceable parts inside.
•
The power system is certified for use in restricted access locations only.
•
All operators must be trained to perform the emergency shutdown procedure.
•
For Hybrid UPS configurations, see section 8 to replace internal fuses.
•
The power system must be connected only to a dedicated branch circuit.
•
Equip the utility service panel with a circuit breaker of appropriate rating.
•
Do not exceed the output rating of the system when connecting the load.
•
External metal surface temperatures on the rear of the AMPS80 HP system can exceed 70°C. Use caution when working around the equipment while it is in operation.
•
Always use proper lifting techniques when handling units, modules, or batteries.
•
The power system contains more than one live circuit. Voltage may still be present at the output even
when the input voltage is disconnected.
•
Minimize the risk of sparks and wear on the connectors. Always switch off the inverter’s battery circuit
breaker before connecting or disconnecting the battery pack.
•
In the event of a short-circuit, batteries present a risk of electrical shock and burns from high currents.

•
Only use insulated tools when handling batteries or working inside the enclosure.
•
Remove all rings, watches and other jewelry before servicing batteries.
•
Recycle used batteries. Spent or damaged batteries are environmentally unsafe. Refer to local codes for
the proper disposal of batteries.
•
A disconnect switch shall be provided by others for the AC input and AC output circuits.
•
Risk of Electric Shock and Fire Hazard: replace fuse with the same type and rating.
1.3 External Battery Safety
•
The power system requires an over-current protection device for the external batteries. The maximum
allowable current is typically 450A but can be less depending on the model. Follow the local electrical
codes.
•
Ensure that the external battery connection is equipped with a disconnect.
•
If the batteries are stored for extended periods before the installation, charge the batteries at least once
every three months to ensure optimum performance and maximum battery service life.
•
Refer to the battery manufacturer’s recommendation to select the correct float and equalize charge voltage settings. Failure to do so can damage the batteries. Verify that the battery charger’s float and equalize settings are correct.
•
The batteries are temperature sensitive. During extremely cold conditions, a battery’s charge acceptance is reduced and requires a higher charge voltage. During extremely hot conditions, a battery’s
charge acceptance is increased and requires a lower charge voltage. To allow for changes in temperature, the battery charger must be equipped with a temperature compensating system. For Hybrid UPS
configurations, refer to the rectifier manual for information about temperature compensation.
•
If the batteries appear to be overcharged or undercharged, first check for defective batteries and then
verify that the charger voltage settings are correct.
•
To ensure optimal performance, inspect the batteries according to the battery manufacturers recommendations. Check for signs of cracking, leaking, or unusual swelling. Some swelling is normal.
•
Check the battery terminals and connecting wires. Periodically clean the battery terminal connectors
and retighten them to the battery manufacturer's torque specifications. Spray the terminals with an approved battery terminal coating such as NCP-2 or No-Ox.
•
Verify that the polarity of the cables are correct before connecting the batteries to the power module. The
polarity is clearly marked on the batteries. The battery breaker will trip and the rectifiers may be damaged if the cables are connected with the wrong polarity.
1.4 Utility Power Connection
Connecting to the utility must be performed by qualified service personnel only and must comply with local
electrical codes. The utility power connection must be approved by the local utility before the installation.
8
026-069-B0 Rev G
1.5 Equipment Grounding
To provide a ready, reliable source of backup power, the power system must be connected to an effective
grounding and earthing system. The grounding system must be designed to protect both personnel and
equipment.
WARNING!
Low impedance grounding is mandatory for personnel safety, critical for the proper operation of the system, and must be in place and connected to the system before the supply
cables are connected.
1.5.1 Safety Ground
The safety ground is a two-part system – the utility service ground and the power system ground.
Utility Service Ground
As a minimum requirement for the protection of equipment, the local utility service must provide a low-impedance path for fault current return to Earth. This must meet or exceed the requirements of the US National
Electrical Code or the Canadian Electrical Code.
Power System Ground
The power system ground consists of a low-impedance connection between the enclosure and an Earth
Ground, which must be located at least six feet away from the utility earth connection.
1.5.2 Lightning Strike Ground
Lightning strikes, grid switching, or other power surges on the power line and/or communications cable
can cause high-energy transients that can damage the power or communications systems. Without a lowimpedance path to the ground, the current will travel through wires of varying impedance, which can produce
damaging high voltages. The best method to protect the system from damage is to divert these unwanted
high-energy transients along a low-impedance path to the ground.
See section 7.7 for a description of the surge suppression modules installed in the AMPS80 HP.

2. Product Description
The Alpha Modular Power System 80HP (AMPS80 HP) is a unique, high performance AC and hybrid AC/
DC power system that is ideally suited to provide highly reliable back-up power to cable headend, telecom or
server room facilities.
The AMPS80 HP features hot swappable 2.5 kVA/2.0 kW inverter modules and optional 1.8 kW rectifier modules that are the building blocks of a highly reliable power system. A smart, unified controller with an integrated Ethernet/SNMP monitors and manages both inverter and rectifier modules through a web based GUI and
a local LCD touch screen. The AMPS80 HP is designed to be installed in a climate-controlled environment
where ambient temperatures are between -20°C to 40°C.
2.1 Theory of Operation
Each AMPS module includes a reliable 48 VDC to 120 VAC inverter as well as an AC-to-DC rectifier. When
AC Mains is available, AC power is converted to a high voltage DC bus, which is then converted back to
AC. In this high performance (HP) mode, AMPS delivers fully conditioned, line-regulated telecom-grade AC
power with 94% system efficiency.

When AC Mains is unavailable, DC battery power is converted to AC with zero transfer time. An intelligent
high voltage DC bus decides when to draw power, and how much power to draw, from AC or DC source.
During AC input brownout condition, output power is supplemented by battery power.
AC to DC input transfer can also be automatically triggered via the system controller to enable advanced
operation such as utility peak shaving.
In case of a fault, advanced DSP controls allow the AMPS module to isolate itself, while the rest of the system
continues to power the load (with reduced output).

AMPS modules also have a ‘Boost’ over-current feature with 10 times the rated current capacity for 20ms, allowing it to trip breakers downstream, thus protecting the load.
2.1.1 AC or DC input priority
The user can choose either AC or DC input priority. If AC priority is chosen, the AMPS80 HP acts more
like an on-line, double conversion UPS. If AC commercial power is available, this power is filtered twice
and passed to the AC output. If the AC commercial power fails, the DC converter simply takes over and
supplies the power from the batteries.
If DC priority is chosen, the AMPS80 HP acts more like an Inverter with AC bypass function. Normally,
power is drawn from the batteries. If DC power fails, the AC-DC converter takes over, still providing regulated and filtered power to the load.
026-069-B0 Rev G
11
2.2 System Components
The AMPS80 HP consists of a number of individual subsystems designed to work together to provide highly
reliable, filtered power in support of the load. A typical system contains the following:
1. Main Wiring Access Panel: AC input and output as
well as Safety Extra-Low Voltage (SELV) DC battery
connections are accessed through the front panel and
fed through the opening at the top of the rack.
1
2. Rectifier AC Input Breakers (optional): Provide a
means to switch off the rectifiers independently of the
inverters.
3. Inverter AC Input Breaker: Serves as the main
disconnect for the inverter AC input.
2
4. Maintenance Bypass Switch (MBS) (optional): Can
be used to route power directly from the AC input to
the AC output, bypassing the inverter modules.
3
4
5. Inverter AC Output Breaker: Serves as the main
disconnect for the inverter AC outputs.
5
6. CXC Unified System Controller with integrated
Ethernet/ SNMP: Monitors and manages both
inverter and rectifier modules through a web-based
GUI and local LCD touch screen. This is a SELV
controller.
6
7
8
7. DC Input Breakers (optional): Provide SELV DC
power to each Inverter module.
8. T2S Inverter Control Card: Communicates with the
CXC Unified controller. This is a SELV Controller.
9. Inverter Modules and shelves: Up to 9 shelves
containing 4 hot-swappable 2500 VA / 2000 W inverter
modules on each shelf.
9
10. Rectifier Modules and shelves (optional): Two
shelves contain up to four hot-swappable 1800 W
rectifier modules on each shelf. The rectifiers are used
as the SELV DC battery charging component of a
hybrid system.
Each rectifier shelf is only connected to one of the DCbattery feeds: the top shelf to DC1, and the bottom
rectifier shelf is connected to DC4. In a system with
four independent battery feeds, two of these battery
banks will not be charged from the AMPS80 HP
rectifiers.

3.6 How to Configure Inverters in AC Input Groups, AC Output
Groups and DC Input Groups
The following sections show how to distribute the inverters among the phases and also suggests how to distribute the DC input to the inverters.
3.6.1 AC Input Groups/ AC Output Groups
The CXC controller provides an interface to assign inverters to phases (Inverters > Group Mapping).
The logical approach is to match the configuration of inverters in the AC Input Group to the configuration of
inverters in the AC Output Group as shown. See Figure 9 also for three Input Groups.
Turn off the inverters to configure
AC Output Groups by clicking the
green power icon.
These groups of inverters can then be monitored as a unit in the View Group Status screen.
Figure 8 — Monitotring AC Input Groups, AC Output Groups and DC Input Groups
026-069-B0 Rev G
27
3.6.2 DC Input Groups
The configuration of the DC input to the inverters provides several different ways to monitor DC input power
and input current. The number of DC Input Groups (maximum eight) is set in the Inverters > Group Mapping
screen and monitored as a unit in the View Group Status screen. The following table gives examples of possible configurations.
Monitoring
DC Source
Bulk
Assign all inverters to DC Input Group 1.
Dual Input
For example:
Assign all the inverters in column 1 & 2 to DC Input Group 1.
Assign all the inverters in shelves 3 & 4 to DC Input Group 2.
Quad Input
For example:
Assign all the inverters in column 1 to DC Input Group 1.
Assign all the inverters in shelves 2 to DC Input Group 2.
Assign all the inverters in column 3 to DC Input Group 3.
Assign all the inverters in shelves 4 to DC Input Group 4.

5. System Installation
The AMPS80 HP system is pre-configured from the factory for a single AC feed per phase for inverters, a
maintenance bypass switch, and rectifiers if present.
The installer is responsible for connecting the following:
•
Utility input to the system (120 V line to neutral)
•
Battery strings
•
System to the load
•
Chassis and battery return to the reference ground
Reference Notes:
•
If the AC input neutral is connected, remove the neutral to ground bonding wire. The neutral to ground
wire is provided for systems without AC Input connections in which case the inverter output is considered a separately derived source and the AC output neutral must be connected to earth ground.
•
In a 3-phase system equipped with an internal maintenance bypass switch and a load with a significant
distortion power factor, it is strongly recommended to provide the AC input and AC output connection
with a double neutral feed. Non-power factor corrected IT power supplies with rectified-capacitive loads
can contain high levels of 3rd harmonics that are created in such 3-phase systems. The current in the
neutral line can easily be twice the current in the line currents.
•
DC tie bars are supplied to allow dual A/B battery feed (DC1 tied to DC2 and DC3 tied to DC4) or single
battery feed (DC1 - 4 are tied)
•
If the system is equipped with the optional rectifiers, each rectifier shelf in a hybrid system is only connected to one of the DC- battery feeds: the top shelf to DC1, and the bottom rectifier shelf is connected
to DC4. In a system with four independent battery feeds, two of these battery banks will not be charged
from the AMPS80 HP rectifiers. When using two independent A/B feeds, DC1 should be tied to DC2 and
DC3 tied to DC4 at the AMPS80 HP DC connection points. Tie bars are provided.
* Connections and components relating to L3 are only present for 120/208 V, 3-phase systems.
** Connections and components relating to L2 are only present for 120/240 V split phase and 120/208 V
3-phase systems.

2. All external wiring by others.
3. Inverter main input must always include a neutral connection.
4. Power and control cables must be in separate conduits.
5. N-G shorting jumper is factory-installed for inverter-only systems. Remove if AC input ground is
connected (#5 on Figure 20).
6. Where rectifier is fed separately from AC (#6 on Figure 20), remove these wires during installation—see
section 4.7.1.
7. L3 is only used with 3-phase systems.
8. Four independent battery strings can be connected. Shorting jumpers are provided for single or dual DC
feed ((#8 on Figure 20).
WARNING!
To maintain the security of all SELV Circuits in the AMPS80, connect to other equipment of
the same circuit type: signaling/alarm circuits, emergency power off (EPO) circuits, relay
contacts, Ethernet or CANBUS.

6.3 Using the CXC Unified System Controller
The CXC controls the AMPS80 HP system and allows the user to set wide variety of parameters regarding the
alarms and operational functionality of the rectifier and inverter modules.
The following guide provides a brief overview of the controller; in-depth information can be found in the Technical Manual for the Cordex Controller Software.
6.3.1 Software Overview
The CXC software enables control of an entire DC + AC power system via the CXC central touch screen user
interface or web based monitoring and control interface. The software also allows the user to control temperature compensation, auto equalization, remote access, and battery diagnostics.
Figure 39 — CXC system controller
User interface
Located on the front panel of each model is a 160-x-160-pixel touch screen liquid crystal display. This graphical user interface (GUI) enables a person to interact with screen selectable items.
LED lights
Each CXC has three LEDs located on the front panel. These are used to display the alarm status of the power
system, CXC progress and status during startup, and file transfers.
Alarm conditions
The CXC illuminates the LED that corresponds to the system alarm status. The following show the corresponding alarm status for each LED color:
•
Green – OK, no alarms present.
•
Yellow – Minor alarm is present (no major alarms).
•
Red – Major alarm is present.
•
Only one LED is illuminated at a time during alarm conditions.

6.3.2 Communication and Control Connections
Remove two screws and fold the controller front panel down to access the communication and control connectors.
NOTE:
The breakers located at the top of the AMPS80 (see Figure 1) protect the wiring to the
CXC and alarm contacts of the different auxiliary contacts on the AC inverter input and output breaker, the TVSS and the MBS.
Input and output signal connections
Controller Ethernet port
6.3.3 Quick Start
1. To initiate a startup routine, switch on the power to the controller by closing the battery breaker. The
controller performs a short self-test as it boots up. Alarm alerts are normal. The LEDs perform a scrolling
pattern to indicate there is activity. Wait for the startup routine to finish.
2. Check and adjust alarms and control levels in the CXC submenus.
3. Check and adjust group settings in the INVERTERS and RECTIFIERS submenus; e.g. float, equalize
voltage, etc.
4. Verify COMMUNICATIONS settings as needed.
5. Program the CXC TEMP COMP and AUTO EQUALIZE settings as needed.
6. Test relay OUTPUT ALARM\CONTROLS as needed; e.g. Major Alarm, CEMF, etc.
60
026-069-B0 Rev G
6.3.4 Startup and Reset Procedure
When the CXC is powered-up or reset, it will first perform a 15 second self-test before displaying the Cordex
logo. The three front-panel LEDs illuminate temporarily, and then extinguish after the system has finished its
self-test. The GUI then displays the power system parameters during Normal operating mode.
6.3.5 Normal Operation
This is the default-operating mode or “home page.” The GUI displays system status information and monitors
all input channels. The Analog Signals Display on the home page show two lines of text for system voltage
and current by default.
Each active area is touch sensitive and responds best to a stylus suited for this purpose.

A matrix of buttons allows the supervisor to map (enable/disable) the inverter's assignment per group for all
of the acquired inverters in the system.
Ensure phases are configured
correctly before mapping inverters in the new groups and turning
them on.
"Power Buttons"
Click these buttons to switch
the inverter ON/OFF. Use with
caution.
Green = inverter is ON
Black = inverter is OFF
Amber/Red = inverter ALARM
Figure 47 — Group mapping window
Power buttons – Green indicates an inverter is turned ON. An amber/orange/yellow color indicates the
inverter is in a recoverable error. The user can attempt to turn on the unit. The red color indicates the inverter
is in an irrecoverable error and there is nothing the user can do to turn on the unit. Black indicates an inverter
is manually OFF. Adding/removing groups (columns) may take a few seconds to incorporate the change.
Changing the radio style buttons (rows) will also take time to apply changes; for example, approximately two
seconds for one inverter and up to ten seconds for the maximum number of inverters (32).
If there are inverters mapped to a column, disabling a column is prevented and a warning message is displayed.
All inverters must be turned OFF to enable the AC Output Groups column buttons. The AC Output Groups of
an inverter in the ON state cannot be changed. The radio buttons for that inverter AC output group will remain
disabled until the inverter is turned OFF.

•
High voltage (OVP) shutdown
•
Thermal shutdown
•
Local shutdown
•
UPF fail
•

The LED will flash (~2Hz) when a minor alarm is detected; if the modules output capability has been reduced
or a minor component failure is detected during the
following conditions:
•
VAC meter fail
•
AC foldback
•
Remote equalize
•
Fan fail
•

6.4.2 LED Activity During Rectifier Software Upload
When a rectifier software upload is in progress, the LEDs will behave in a distinctly different way to indicate
new rectifier software is being transferred from the CXC.
When a rectifier data transfer is in progress, all three LEDs will flash in a sequence lasting 1.5 seconds. When
the last LED is lit, the sequence is repeated beginning at the first LED.
6.4.3 LED Activity During Rectifier ‘Locate Module’ Command from
Controller
When the ‘locate module’ command has been received from the CXC, the LEDs will behave in another distinct fashion so that the rectifier is easier to visually identify among adjacent rectifiers.
This state is entered when commanded via the CXC. The LEDs will flash in a ping-pong pattern repeating
every 2 seconds.
The ping-pong pattern lights each LED sequentially. After the last LED is lit, each LED is lit in reverse sequence. When the first LED is lit, the pattern repeats. The effect makes it appear as if the light is bouncing
between the first and last LED.
6.4.4 True Rectifier Module Fail Alarm
The power modules have a “true” fail alarm. This provides a true indication of the power module’s ability to
source current. When the module’s output current drops below 2.5% of the rated output a low output current
condition is detected and the Module Fail detection circuit is activated. This circuit momentarily ramps up the
output voltage to determine if the module will source current. If no increase in current is detected, the Module
Fail alarm is activated. The module will test once every 60 seconds for the condition until current is detected.
Output voltage ramping will cease upon detection of Current1. A minimum 2.5% load is required to avoid the
Ramp Test Fail alarm; this can typically be provided with the parallel system battery. Activation of this alarm
could indicate a failed module or a failed load.
For Cordex rectifier systems without batteries (or with a very light load; below 2.5% of rated output) it is
recommended that the ramp test be disabled to avoid nuisance alarms. The Ramp Test feature is enabled/
disabled via the CXC menu item: Rectifiers, Configure Settings.

7.4 Replacing the T2S Inverter Control Card
CAUTION!
Perform this procedure with the system in bypass mode and/or during a scheduled
maintenance window.
Step 1: Removal
To release the T2S from the shelf, insert a small flat screwdriver in the
square hole under the USB port and lift up the lock pin. Then pull out the
module.
Step 2: Replacement and Initialization
Insert the new T2S into the system. Once inserted, it will take about 10
minutes (or longer with fully loaded systems) for the T2S to initialize with
the inverter modules.
CAUTION!
Ignore error/alarm conditions displayed during initialization. Do not remove any system
components during the initialization sequence. Interruptions to the initialization sequence
can result in software corruption and reduced functionality.
When the T2S is initially
inserted, all LEDS are off
for a few seconds.
Initialization is in progress:
Top 2 LEDs: solid green
Bottom LED: off
DO NOT INTERRUPT
Initialization complete:
Top 2 LEDs : solid green
Bottom LED: flashing green
Figure 57 — T2S LED sequence during initialization

026-069-B0 Rev G
Step 3: Inventory Update
When the initialization sequence is complete (top two LEDs solid green and the bottom LED flashing green),
use the CXC touch display to perform an inventory update. The CXC memory is cleared of the original T2S
and updated to the latest installed T2S.
Allow up to five minutes upon completion of the inventory update for the CXC to display the inverter
information.

7.6 Replacing an AIM2500/1500 Inverter Module
CAUTION!
This system is designed for use with Alpha AIM2500 inverter modules (Alpha p/n 014-20120). Use of alternate inverter hardware and/or unapproved firmware versions may cause
system instability and will invalidate system warranty. Consult Alpha customer service or
technical support for additional details.
CAUTION!
Improper installation or removal of modules can break latching components.
Removing a module from a working system generates an alarm, which will not clear until the module is replaced or the number of modules in that phase is reduced by the number of modules removed.
STEP1:
Insert a flat head screw driver into the center flap
notch and pry open the center flap. Then pull out
the module by pulling on the center flap with both
hands.
STEP2:
With the module plastic front grill in the open/
unlocked position, slide the module all the way
into the slot Press the module into place and
ensure connection is engaged. Close the flap.
Unlock
A new module can take between 5 and 10 minutes
to synchronize with the T2S controller and clear any
alarms. Do not interact with the system during the
initialization process.
When the initialization sequence is complete, the
three LEDs on the left hand side of the inverter module turn a solid green.

8. Troubleshooting
8.1 Non Recoverable Error
Inverter status LEDs
Output power
status LEDs
The status LEDs illuminate permanently red when a non recoverable error occurs. Thanks to its double input
port, the AMPS80 HP inverter module will actually stop when either the output stage is non recoverable or
when both input stages are faulty. Generally, a non-recoverable error cannot be erased and the module must
be returned for repair.
8.2 Recoverable Error
A recoverable error is a kind of protection that acts when, some parameters exit temporarily from their proper
limit range. Stopping the module or removing it from its slot and plugging it back in may solve the problem.
For more detailed diagnostics, use the Ethernet port of the CXCR to view the alarm description. See Alarm
descriptions below. The inverter alarms can be found in Inverters > View Live Status.

8.3 Alarm Codes
All alarm codes are listed in Table K. The following alarm codes are included here as well to provide more
information.
8.3.1 No Ethernet Communication
For a direct connection to the CXCR, verify that you are using a cross over cable, that your wireless connection is turned off, and that your local area network connection is set up as shown below.
Reset the CXCR by using the LCD touch screen as shown below:

026-069-B0 Rev G
8.3.2 System Saturated
The system saturated alarm defaults to 80% load on the non redundant inverters. To remove this alarm, add
more inverters or reduce the amount of redundant units.
8.3.3 AC Secondary Source Lost
The AC Secondary alarm happens when the DC is removed from the system and when settings in the group
mapping screen are incorrect.
Click to remove
026-069-B0 Rev G
Click to add
89
8.3.4 AC Mains Lost
The AC Mains Lost alarm happens when the AC input does not meet the correct voltage, phase, or frequency. When AC mains is lost the UPS goes into Inverter Mode. This alarm is sometimes accompanied by other
alarms.
Both the T2S and CXC software give inverter alarm AC Mains Source Lost when a column is not used (or accidentally added) in the AC Input Group in the Inverters>Group Mapping screen.
8.3.5 Manual Off
The Manual Off alarm happens when one or more inverters have been turned off in the group mapping
screen.
8.3.6 Phase Not Ready
Phase not ready alarm happens when the inverter thinks it should be in a certain phase and the input to it is
another phase. This can be correct either by changing the input wiring to the AMPS80 HP or by changing the
phase in the group mapping settings screen.

TOO MANY
STARTS
Too many starts in 1 minute
( 10 times in 1 minute)
8
This problem usually
happens when the input
source is not powerful
enough to supply the load.
The inverter has a correct
DC voltage and starts. After it
has started, the power taken
on the input source is too
important and the DC voltage
falls under the minimum and
the inverter stops. After 10
attempts to start, the inverter
stops. The aim of this error is
to avoid a situation in which
the inverter keeps starting
and stopping.
Correct the problem : increase
the input power, reduce the
load, increase the voltage
hysteresis… Then, turn the
module OFF to clear the error
and back ON (or, if you have
no access to the supervision,
unplug and replug the module)
OVERCURRENT The AC output current has

The most likely cause is that
energy has been reinjected
into the module (by the load,
if the Acout has been shortcircuited with the grid…)
Check if there is a problem
around the module which could
explain the error. Then, reset
the module and try again. If the
problem persists, replace the
module.

10. Configuration Parameters
The inverter settings have their own configuration file which is not part of the full site configuration file. The
default configuration settings, described in the following sections, are presented in a logical manner, but in
reality they are one contiguous file. All available parameters are described in this section, though not all are
used in a basic installation.
CAUTION!
Configure parameters with care as mistakes will shut the system down with resulting power
loss to the load. Modifying the configuration settings, using a text editor, can have dire consequences and should be undertaken by advanced users only.
10.1 Transferring Inverter Settings to Another System
1. To transfer inverter settings to another system, first save the inverter configuration file to a local disc (Main
Menu > Inverters > Manage Config File).
2. Then browse to locate the file and upload it to the system at another site.

Figure 60 — Manage Config File window
10.2 Examples of Modifications to Configuration Parameters
10.2.1 Changing the Saturation Level Alarm
The saturation alarm threshold is the level of load that generates an alarm indicating there is a risk of overload. This parameter takes into account the redundancy already defined. For example, if a system has 4
modules and 1 is redundant –> 80 % of 3 modules.
1. Save the inverter configuration file to a local disk (Main Menu > Inverters > Manage Config File).
2. Open the file with a text editor.
3. Scroll down to the saturation alarm threshold:
;556;
;Saturation alarm threshold;
;100;
;%;
4. Change the default to desired value in the range 80 to 100%.
5. Save the file to the local disk.
6. Upload to the inverter system.
7. Save inverter configuration file to the local disk with a different name than before.
026-069-B0 Rev G

10.2.2 Changing the Synchronization Tracking Speed Operation
This parameter sets the speed with which the module tries to synchronize ACout.
1. Save the inverter configuration file to a local disk (Main Menu > Inverters > Manage Config File).
2. Open the file with a text editor.
3. Scroll down to Synchronization Tracking Speed
;100;
;Synchronization Tracking Speed;

0.1
5. Save the file to the local disk.
6. Upload to the inverter system.
7. Save the inverter configuration file to the local disk with a different name than before.
10.2.3 Changing the Walk-in Mode for Generator Operation
Walk-in mode needs to be set if a generator is used in bypass mode. Walk in mode stops the oscillation that
causes DC mode to activate. It allows a progressive comeback, slowly removing DC power while slowly
increasing AC power.
1. Save the inverter configuration file to a local disk (Main Menu > Inverters > Manage Config File).
2. Open the file with a text editor.
3. Scroll down to Walk-in Mode
;62;
;Walk-in Mode (0 : No, 1 : Yes);
;0;
;;
4. Set the parameter to 1.
5. Save the file to the local disk.
6. Upload to the inverter system.
7. Save the inverter configuration file to the local disk with a different name than before.

About CSA and NRTL
CSA (Canadian Standards Association also known as CSA International) was established in 1919 as an independent testing laboratory in Canada. CSA received its recognition as an NRTL (Nationally Recognized Testing Laboratory) in 1992 from OSHA
(Occupational Safety and Health Administration) in the United States of America (Docket
No. NRTL-2-92). This was expanded and renewed in 1997, 1999, and 2001. The specific
notifications were posted on OSHA’s official website as follows:
•
Federal Register #: 59:40602 - 40609 [08/09/1994]
•
Federal Register #: 64:60240 - 60241 [11/04/1999]
•
Federal Register #: 66:35271 - 35278 [07/03/2001]
When these marks appear with the indicator “C and US” or “NRTL/C” it means that the
product is certified for both the US and Canadian markets, to the applicable US and
Canadian standards. (1)
Alpha rectifier and power system products, bearing the aforementioned CSA marks, are
certified to CSA C22.2 No. 950 and UL 1950, or CSA/UL 60950. Alpha UPS products,
bearing the aforementioned CSA marks, are certified to CSA C22.2 No. 107.3 and UL
1778.
As part of the reciprocal, US/Canada agreement regarding testing laboratories, the
Standards Council of Canada (Canada’s national accreditation body) granted Underwriters Laboratories (UL) authority to certify products for sale in Canada. (2)
Only Underwriters Laboratories may grant a licence for the use of
this mark, which indicates compliance with both Canadian and US
requirements. (3)
NRTLs capabilities
NRTLs are third party organizations recognized by OSHA, US Department of Labor, under the NRTL program.
The testing and certifications are based on product safety standards
developed by US based standards developing organizations and are
often issued by the American National Standards Institute (ANSI). (4)
The NRTL determines that a product meets the requirements of an
appropriate consensus-based product safety standard either by
successfully testing the product itself, or by verifying that a contract
laboratory has done so, and the NRTL certifies that the product meets the requirements of the product safety
standard. (4)
Governance of NRTL
The NRTL Program is both national and international in scope with foreign labs permitted.
