You can also attach the power supplies to the back of an OmniSwitch 6850 Series chassis directly as well 
as using cables at the same time, as shown in the diagram below. 

In addition to the installation steps described in 

and 

“Connecting a Power Supply with a Cable” on page 2-81 

DC power supplies (e.g., the PS-

120W-DC) have the following additional considerations:

• Connect to a -48V or -60V 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.

Note. Refer to the wiring diagram for information on connecting the DC power supply to a DC power 
source.
