DC Power Supply Considerations
DC power supplies 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.
