Perform these four tasks in the order they are described.

Connecting the DC Wiring Harness to the DC Source Voltage

The EPS-150DC power module must be connected to a DC power source. A three-wire, 6-foot long DC
wiring harness (Figure 105) is included with the EPS-150DC unit. The DC wiring harness must be
properly connected to the DC source voltage at your facility by a qualified electrician before the
connector on the wiring harness can be attached to the DC power supply socket on the rear of the unit.
See Appendix B, "Technical Specifications"
specifications to be used in connecting the wiring harness to the DC source voltage.
WARNING!
Wiring the EPS-150DC DC wiring harness to your facilities DC source voltage must be performed by a qualified,
licensed electrician. After the wiring harness is connected to a permanent DC voltage source by a qualified, licensed
electrician, you can remove, replace and maintain the ESP-150DC without further electrician assistance. However,
always be sure that the DC circuit is de-energized before connecting or disconnecting the DC power connection at
the rear of the EPS-150DC unit.
CAUTION
The DC wiring harness must be properly connected to a DC main circuit breaker or fuse rated no greater than 20 A.
Provide proper connection and strain relief on the DC wiring harness in accordance with all local and national
electrical codes.

NOTE
Each wire on the harness has been properly marked for proper attachment to the DC power source. Leave these
labels on each lead wire for future reference.
