wiring harness at the DC power socket on the rear of the EPS-150DC unit, and before
connecting or disconnecting the redundant power cord between the switch and the
EPS-150DC unit.
Installing an EPS-150DC unit consists of the following tasks:
•
Connecting the DC wiring harness to the DC source voltage (see the next section).
This task must be performed by a licensed, qualified electrician.
•

Perform these four tasks in the order they are described.
Connecting the DC Wiring Harness to the DC Source Voltage
A three-wire, 6-foot long DC wiring harness
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
information about connector pinouts and for DC power 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.

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.
