Warning

When installing or replacing the unit, the ground connection must always be made first and
disconnected last.

Statement 1046

Caution

Grounding the chassis is required if you are using DC power supplies, even if the rack is already
grounded. A grounding pad with two threaded M4 holes is provided on the chassis for attaching a
grounding lug. The ground lug must be NRTL listed. In addition, the copper conductor (wires) must be
used and the copper conductor must comply with NEC code for ampacity.

To attach the grounding lug and cable to the chassis, follow these steps:

Step 1

Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of
the grounding cable.

Step 2

Insert the stripped end of the grounding cable into the open end of the grounding lug.

Step 3

Use the crimping tool to secure the grounding cable in the grounding lug.
