Connecting the EPS-150DC to a Switch
If you are connecting the EPS-150DC unit to a Summit X450a-48tDC switch, you must ground the
switch before connecting power. For instructions on grounding the switch, see
“Grounding a Summit
DC-Powered Switch” on page 236
.
WARNING!
Always be sure that the DC circuit is de-energized before connecting the EPS-150DC to the switch.
One end of the EPS-150DC cord has a keyed connector to ensure correct alignment of the connector
(
Figure 262
). The key is a plastic tab on the connector housing that fits into the EPS-150DC unit.

To connect the EPS-150DC to a switch:
1
Verify that the DC power is turned off at the source.
2
Identify the keyed end of the redundant power cable.
3
Holding the keyed connector so that the side labeled “Top” is facing up, connect the EPS-150DC
redundant power cable to the power supply unit (see
Figure 263
).

Align and tighten the connector retaining screws to secure the cable connector to the power supply
unit.
