AC Power - Standalone Modules
Secure the ground wire to the ground screw located on the back of the module.
Route the power cord through the provided strain relief for additional support and
connect the barrel connector at the end of the wire on the AC/DC adapter to the barrel
connector on the module. Connect the AC/DC adapter to the AC outlet. Confirm
that the module has powered up properly by checking the Power LED located on
the front of the module.

DC Power - Standalone
This module is intended for installation in restricted access areas. ("Les matériels
sont destinés à être installés dans des EMPLACEMENTS À ACCÈS RESTREINT").
A restricted access area can be accessed only through the use of a special key, or
other means of security.
The over current protection for connection with centralized DC shall be provided in
the building installation, and shall be a UL listed circuit breaker rated 20 Amps, and
installed per the National Electrical Code, ANSI/NFPA-70.
Appropriate overloading protection should be provided on the DC power source
outlets utilized.
The standalone module requires +8 to +32VDC inclusive of tolerances (0.6A @
9VDC max rated power). See specification table for specific model requirements.
Appropriate overloading protection should be provided on the DC power source
outlets utilized.

WARNING: Only a DC power source that complies with
safety extra low voltage (SELV) requirements can be
connected to the DC-input power supply.
WARNING REGARDING EARTHING GROUND:
o
This equipment shall be connected to the DC supply
system earthing electrode conductor or to a bonding
jumper from an earthing terminal bar or bus to which the
DC supply system earthing electrode is connected.
o
This equipment shall be located in the same immediate
area (such as adjacent cabinets) as any other equipment
that has a connection between the earthed conductor of
the same DC supply circuit and the earthing conductor,
and also the point of earthing of the DC system. The DC
system shall not be earthed elsewhere.
o
The DC supply source is to be located within the same
premises as this equipment.
o
There shall be no switching or disconnecting devices in
the earthed circuit conductor between the DC source and
the earthing electrode conductor.
Locate the DC circuit breaker of the external power source, and switch the circuit
breaker to the OFF position.
Prepare a power cable using a three conductor insulated wire (not supplied) with
12AWG to 14AWG thickness. Cut the power cable to the length required.
Strip approximately 3/8 of an inch of insulation from the power cable wires.
Connect the ground wire to the grounding screws on the back of the module.
Connect the power cables to the module by fastening the stripped ends to the DC
power connector.
WARNING: The positive lead of the power source must be connected to the
"+" terminal on the module and the negative lead of the power source to the
"-" terminal on the module as shown above.
Power Options
WARNING: Note the wire colors used in making the positive, negative and
ground connections. Use the same color assignment for the connection at
the circuit breaker.
Connect the power wires to the circuit breaker and switch the circuit breaker ON.
If any module are installed, the Power LED will indicate the presence of power.
During the installation, ensure that the ground potentials are maintained throughout
the system connections. This includes but not limited to the power source ground
and any shielded cabling grounds.
