Handling Energized Products
General Safety Practices
Do not touch or tamper with the power supply when the power cord is connected. Line voltages
may be present inside certain products even when the power switch (if installed) is in the OFF
position or a fuse is blown. For DC-powered products, although the voltages levels are usually
not hazardous, energy hazards may still exist.
Before working on equipment connected to power lines or telecommunication lines, remove
jewelry or any other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use.
Grounding is provided by connecting the mains plug to a wall socket with a protective earth
terminal. If an earth lug is provided on the product, it should be connected to the protective
earth at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment
should be mounted only in earthed racks and cabinets.
Always make the ground connection first and disconnect it last. Do not connect
telecommunication cables to ungrounded equipment. Make sure that all other cables are
disconnected before disconnecting the ground.
Connecting AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power
to the product is 16A. The circuit breaker in the building installation should have high breaking
capacity and must operate at short-circuit current exceeding 35A.
Always connect the power cord first to the equipment and then to the wall socket. If a power
switch is provided in the equipment, set it to the OFF position. If the power cord cannot be
readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or
emergency switch is installed in the building installation.
In cases when the power distribution system is IT type, the switch must disconnect both poles
simultaneously.
Connecting DC Power
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference
to the ground. Any single pole can be externally grounded.
Due to the high current capability of DC power systems, care should be taken when connecting
the DC supply to avoid short-circuits and fire hazards.
DC units should be installed in a restricted access area, i.e. an area where access is authorized
only to qualified service and maintenance personnel.
Make sure that the DC power supply is electrically isolated from any AC source and that the
installation complies with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power
to the product is 16A. The circuit breaker in the building installation should have high breaking
capacity and must operate at short-circuit current exceeding 35A.
Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate
the circuit breaker of the panel board that services the equipment and switch it to the OFF
position. When connecting the DC supply wires, first connect the ground wire to the
corresponding terminal, then the positive pole and last the negative pole. Switch the circuit
breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated
in the building installation.
If the DC power supply is floating, the switch must disconnect both poles simultaneously.
Connecting Data and Telecommunications Cables
Data and telecommunication interfaces are classified according to their safety status.
The following table lists the status of several standard interfaces. If the status of a given port
differs from the standard one, a notice will be given in the manual.

up to 30 VAC or 60 VDC.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance
of a qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables.
Do not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both
ends. The earthing and bonding of the ground connections should comply with the local codes.
The telecommunication wiring in the building may be damaged or present a fire hazard in case of
contact between exposed external wires and the AC power lines. In order to reduce the risk,
there are restrictions on the diameter of wires in the telecom cables, between the equipment
and the mating connectors.
Caution
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cords.
Attention
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de
télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In
such cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of
major regulatory bodies. The following instructions may enhance the performance of the
equipment and will provide better protection against excessive emission and better immunity
against disturbances.
A good earth connection is essential. When installing the equipment in a rack, make sure to
remove all traces of paint from the mounting points. Use suitable lock-washers and torque. If an
external grounding lug is provided, connect it to the earth bus using braided wire as short as
possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially
for high-rate data. In some cases, when unshielded wires are used, ferrite cores should be
installed on certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time
configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines
is dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal
conversion loss (LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary
protection against surges on the data lines. Primary protectors should be provided in the building
installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with
plastic connectors (without a grounded metal hood, such as flat cables) to sensitive data lines.
Before connecting such cables, discharge yourself by touching earth ground or wear an ESD
preventive wrist strap.

Chapter 1 Introduction
Functional Description
Power is provided to PFH-4 via a 48 VDC supply. PFH-4 converts the power to 120
or 180 VDC and feeds the power over each of the SHSDL lines, according to the
configuration of the power-feeding DIP switches. SHDSL data moves
transparently from line-in to line-out without disturbance.
Power Indication
A green LED (PWR) indicates when 48 VDC is applied to the device.
Power Feeding Selection and Indication
A DIP switch controls the power feeding for each line. Each line can be configured
to be with or without power feeding by setting the DIP switch for the line in the
following way.
ON activates power feeding
OFF disables power feeding.
A group of indicators (P-FED) indicate the power feeding status of each line,
according to the configuration of each DIP switch:
ON – power feeding is activated
OFF – power feeding is disabled.
Alarm Indications and Fault Protection
Each line has a red LED (ALM LED) that indicates the following faults:
•
Line over-current: Line current is limited to 60mA in case of a current
overload. The line clamps down after about 1 to 2 seconds and stays down
for 10 seconds. If the over-current condition is cleared, the line current
automatically restores.
•
Earth leakage current protection (for 180 VDC model only): Line current is
limited to 15 mA in case the line is shorted to earth. The line clamps down
after about 1 to 2 seconds and stays down for 10 seconds. If the earth
current leakage condition is cleared, the line current automatically restores.
•
Over-temperature protection: In case the control unit overheats, all lines
feeding power are shut down. Hysteretic auto-restart automatically restores
power feeding when the overheating condition is cleared.
PFH-4 has dry contacts for relaying a warning alarm indication:
