o
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.
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.
The DC supply source is to be located within the same
premises as this equipment.
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 12 AWG to 14 AWG 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 power cables to the terminal by fastening the stripped ends to the DC power connector.
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.
Secure the grounding wire to the ground screw. See the figure below for the location of the grounding screw.

or restricted.
NEVER ATTEMPT TO OPEN THE CHASSIS OR
SERVICE THE POWER SUPPLY. OPENING THE
CHASSIS MAY CAUSE SERIOUS INJURY OR DEATH.
