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 123.

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 159). The key is a plastic tab on the connector housing that fits into the EPS-150DC unit to ensure correct alignment of the connector.
