Power cord connection

Caution

Before turning on the enclosure, carry out the grounding checks detailed in “Grounding checks” on page 28.

To attach the power cord:

1Attach the power cords to the power supply modules. The cable strain relief bale fits over and onto the power cord. Lift the bale up first, insert the cable, and secure the bale onto the power cord.

Caution

The power connections must always be disconnected prior to removal of the power supply module from the enclosure.

2Attach the power cord to the power distribution unit in the rack or other power source.

3A Power On LED on the Ops panel indicates whether AC power is present.

Grounding checks

Perform these checks to make sure that a safe grounding system is provided.

•If a rack distribution system is being used.

•Make sure that power is removed from the rack.

•Connect the power cord to the rack distribution system and the enclosure.

•If a direct connection is made with the power cord, make sure that it is connected to the enclosure.

Caution

Some electrical circuits could be damaged if external signal cables or power control cables are present during the grounding checks.

•Check for continuity between the earth pin on the IEC 320 connector on one of the power supply modules and any exposed metal surface of the enclosure.
