DC Power Electrical Safety Guidelines
The following electrical safety guidelines apply to a DC-powered services gateway:
•
A DC-powered services gateway is equipped with a DC terminal block that is rated for
the power requirements of a maximally configured services gateway. To supply
sufficient power, terminate the DC input wiring on a facility DC source capable of
supplying at least 30 A @ -48 VDC for the system. We recommend that the 48 VDC
facility DC source be equipped with a circuit breaker rated at 40 A (-48 VDC) minimum,
or as required by local code. Incorporate an easily accessible disconnect device into
the facility wiring. In the United States and Canada, the -48 VDC facility should be
equipped with a circuit breaker rated a minimum of 125% of the power provisioned for
the input in accordance with the National Electrical Code in the US and the Canadian
Electrical Code in Canada. Be sure to connect the ground wire or conduit to a solid
office (earth) ground. A closed loop ring is recommended for terminating the ground
conductor at the ground stud.
•
Run two wires from the circuit breaker box to a source of 48 VDC. Use appropriate
gauge wire to handle up to 40 A.
•
A DC-powered services gateway that is equipped with a DC terminal block is intended
only for installation in a restricted access location. In the United States, a restricted
access area is one in accordance with Articles 110-16, 110-17, and 110-18 of the National
Electrical Code ANSI/NFPA 70.
