Chapter 7: Installing Summit External Power Supplies

Installing an EPS-150DC Power Supply

NOTE
Install the EPS-T2 before you begin installing the EPS-150DC.
WARNING!
Always be sure that the DC circuit is de-energized before connecting or disconnecting the DC 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.
Installing an EPS-150DC unit in an EPS-T2 (see
●
Connecting the DC wiring harness to the DC power socket on the EPS-150DC (see
●
Connecting the EPS-150DC to a switch (see
●
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 239) 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 for 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.
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.
