CONFIGURATION
3.1
DC Powered Chassis Site Preparation
•
Power source should be available within 5 ft. of the chassis. 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
20Amps, and installed per the National Electrical Code, ANSI/NFPA-70.
•
This equipment requires 18-60VDC/1.0Amp rated power. 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.
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 operating temperature of this equipment is 0 to 50 degrees C. If installed
in a closed or multi-module rack assembly, the operating ambient
temperature of the rack must not exceed the maximum rated 50 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.
•
Never use this equipment to carry any weight except its own. Never use it
as a shelf to support weight of other equipment.

•
Locate the DC circuit breaker, and switch the circuit breaker to the OFF
position.
