WARNING REGARDING EARTHING GROUND:
o

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.
The standard operating temperature of this equipment is 0 to 50 degrees C. If installed in a closed or multi-chassis rack
assembly, the operating ambient temperature of the rack must not exceed the maximum rated 50 degrees C temperature. For
wide temperature models, the operating temperature must not exceed 60 degrees C.
Installation of the equipment should be such that the air flow in the front and back of the chassis is not compromised or
restricted.
Installing this equipment into a rack in such a way as to make it unstable may cause injury or death. Always make sure that
the rack is properly secured, stable, balanced and designed to carry the weight and weight distribution of this equipment.
Never use this equipment to carry any weight except its own. Never use it as a shelf to support the weight of other
equipment.
Locate the DC circuit breaker and switch the circuit breaker to the OFF position.
Prepare a power cable using a three conductor insulated wire (not supplied) with a 14 AWG gauge. 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 chassis by fastening the stripped ends to the DC power connector (see Figure 6 for details on
terminal block polarity).
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. The Power LED on the front of the chassis
will illuminate as well as the Power LED on any installed modules.
NOTE: The fans will not operate until the internal ambient temperature reaches appropriately 50° C. The fans will
turn off once the internal ambient temperature drops below appropriately 40° C.
