DC Power Specifications
In addition to the installation steps described in
“Connecting a Power Supply to the Chassis” on page 3-13
and
“Rack Mounting Power Supplies” on page 3-15
DC power supplies have the following additional
considerations:
•
Connect to a -48V reliably grounded DC SELV source.
•
Use common DC return connections for the DC power supplies. The DC return terminal conductor
should be connected to the equipment frame.
•
The Branch Circuit Overcurrent Protection must be rated a Maximum of 15A.
•
Use 12AWG solid conductors only.
•
A readily accessible disconnect device that is suitably approved and rated shall be incorporated in the
field wiring.
