DC Power Electrical Safety Guidelines
• A DC-powered device is equipped with a DC terminal block that is rated for the power requirements
of a maximally congured device.
• For permanently connected equipment, a readily accessible disconnect device shall be incorporated
external to the equipment.
• For pluggable equipment, the socket-outlet shall be installed near the equipment and shall be easily
accessible.
• Be sure to connect the ground wire or conduit to a solid central oce earth ground.
• A closed loop ring is recommended for terminang the ground conductor at the ground stud.
• Run two wires from the circuit breaker box to a source of 48 VDC.
• A DC-powered device that is equipped with a DC terminal block is intended only for installaon in a
restricted-access locaon. In the United States, a restricted-access area is one in accordance with
