Using the two wires of a 10 AWG cable running from the DC power distribution unit,
connect the black wire into the -48VDC 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 Model.
The supply wires for DC version must be terminated using quick connectors.

Connect the green or green-yellow wire to the system single-point M6x15 "Ground"
bolt.
If the unit is rack mounted, the single-point ground on the MCU must be connected to
the rack with a single conductor and fixed as to prevent loosening. When using bare
conductors, they must be coated with an appropriate antioxidant compound before
crimp connections are made. Tinned, solder-plated or silver plated connectors do not
have to be prepared in this manner.
Replace the transparent plastic caps on the terminal block.
Turn ON the Main that supplies power to the RMX.
Turn ON the circuit breaker on each of the DC Power Rail Modules.
