PROJECT STANDARD SPECIFICATION
operation. The self-test shall identify the parts of the UPS requiring repair in case of a fault.
The system shall be provided with multi-password levels to limit access to software and data.
B.
General: System is to be interposed between normal a.c. power supply and critical load, to
secure a minimum period of continuity of no-break battery back-up for 15 minutes unless
otherwise shown on the Drawings, in case of failure of normal a.c. supply and maintain
output voltage, frequency and phase deviation within specified tolerances.
C.
System is to be [non-redundant][internally (50 percent) redundant (for 3-50 percent
units or chains)][internally 100 percent dual redundant with common battery (for 2-100
percent units or chains)][externally redundant which implies 2 complete UPS units with
2 sets of batteries operating in parallel]. UPS is to be maintained (continuously supplying
load through the inverter), with automatic no-break transfer to or retransfer from alternate
source (bypass) in case of failure or overload on rectifier- battery-inverter system.
D.
Normal a.c. power supply will be available from one protected source fed from either normal
a.c. network or from a.c. Characteristics of output of generator set (when provided) and UPS
system are to be coordinated for best results. Study and advise on special requirements of
generator characteristic output and stability.
E.
System Redundancy: System is to have parallel units interconnected so that normal a.c.
power feeds more than one rectifier/charger in parallel on a common d.c. bus, which in turn
feeds floated battery and more than one inverter in parallel, to give required power output at
critical load. Load sharing circuits are to ensure real and reactive load sharing and provide
reverse power protection between parallel units. Full rated capacity of UPS, in case of failure
of one of the rectifiers or one of the inverter units is to be equally shared by other healthy

SYSTEM OPERATION
A.
Under normal conditions inverter(s) are to be synchronized and phase locked to normal a.c.
supply. Upon loss of normal a.c. supply, battery is to continue supply of no-break power to
inverters, which then free-run on self- generated UPS frequency reference. Upon restoration
of normal a.c. supply, inverters are to re-synchronize to a.c. line, gradually (at slew rate), if
frequency and voltage deviation of normal a.c. supply is within preset limits specified.
B.
Automatic Transfer To Bypass: Static transfer switch is to automatically transfer critical (100
percent load from inverter to by-pass source (which is normal a.c. supply) if:
1.
2.
3.
4.
5.
C.
Inverter output voltage characteristics fall outside specified limits.
Critical load exceeds overload rating of UPS.
Over-temperature is sensed.
Manual (push button) command is given.
Transfer to by-pass mode is to be inhibited, and an alarm initiated if voltage,
frequency and/or phase shift of by- pass power is outside acceptable tolerances.
Re-Transfer To Inverter: Re-transfer of critical load from auto by-pass source to inverter
(UPS mode) is only to be possible under the following conditions:
6.
7.
8.
Inverter output voltage characteristics return to within specified tolerances.
Original load current reduces to within rated full load capacity of UPS.
Re-transfer selector switch is in automatic position.
D.
Lock-out feature is to inhibit re-transfer if by-pass source conditions are outside preset
tolerances or if UPS output and by-pass are not synchronized and phase locked or if UPS
output is not restored to normal conditions.
E.
Normal Power Restored: When normal power is restored following an outage,
rectifier/charger is to initially draw no power except for transformer in-rush current. After
approximately 15 seconds (walk-in time), input power requirements are to rise to power level
to drive critical load and recharge battery.
F.
Provide maintenance disconnecting switch fully rated to carry the full load input current of
the UPS.
G.
The LCS shall forward data to the I2BS within 1 seconds of a request from the I2BS or within
1 seconds of a status change for data on display at a workstation. The LCS shall initiate
action within 1 seconds of receiving a command from the I2BS.
