place. Statement 1075

If you are using the Version 2 930W DC power supply, you connect power using a supplied 3-wire cable

with a keyed connector that plugs into a fixed power input socket on the power supply.

Warning

Before beginning this wiring procedure, turn off the DC power source from your facility’s circuit

breaker to avoid electric shock hazard.

Step 1 Turn off the DC power source from your facility’s circuit breaker to avoid electric shock hazard.

Step 2 Wire the supplied 3-wire connector cable to your facility’s DC power source. Attach the red wire to the

negative lead of your facility’s DC power source.

Note The supplied connector cable contains 8 AWG gauge wires. The recommended facility wire gauge is

8 AWG. The minimum facility wire gauge is 10 AWG.

Step 3 Plug the supplied connector cable into the power input socket on the power supply. Figure 11-6 shows

that the connector is keyed to the socket so that the polarity is aligned correctly.
