Connecting the DC Wiring Harness to the DC Power Socket on the EPS-150DC

After the DC wiring harness is connected to a permanent DC voltage source by a qualified, licensed electrician, you can remove, replace, and maintain the EPS-150DC unit without further electrician assistance.

WARNING!

Always be sure that the DC circuit is de-energized before connecting the DC wiring harness to the DC power socket.

To connect the DC wiring harness to the EPS-150DC unit:

1Verify that the DC power is turned off at the source.

2Plug the DC cable connector into the DC power supply socket on the rear of the EPS-150DC unit.

The pins must align properly for the cable to completely connect. Do not force the cable into the socket until the keyway is aligned properly. Refer to Figure 157 for the DC wiring harness connector and to Figure 158 for the DC power socket location on the rear of the EPS-150DC unit.
