Connecting the RMX 4000 to -48DC SELV Power

1On the DC Power Rail Modules (PRM’s), set the two circuit breakers to OFF. For more information on circuit breaker types, see "Types of DC Circuit Breakers installed on the RMX 4000” on page 1-19.

2Ensure that the cables from the Main that supplies electricity to the DC power units are OFF or disconnected.

3Remove the transparent plastic caps on the terminal block.

4Using the two wires of an 10 AWG cable running from the DC power distribution unit, connect the black wire into the -48 VDC terminal block and the red wire to the RTN terminal block.

•A 10 AWG cable must be used to connect the mains with the RMX 4000 DC Power Rail Module.

•The supply wires for DC version must be terminated using quick connectors.

•Extension cords may not be used.
