Statement 1046—Installing or Replacing the Unit

Warning

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

last.

Warning

Statement 1025—Use Copper Conductors Only

Use copper conductors only.

Caution

Grounding the chassis is required, 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, a copper conductor (wires) must be used and the copper conductor must comply with NEC

code for ampacity.

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.

Step 4

Remove the adhesive label from the grounding pad on the chassis.

Step 5

Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4

screws with washers through the holes in the grounding lug and into the grounding pad.

Step 6

Make sure that the lug and cable do not interfere with other equipment.

Step 7

Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure

adequate earth ground.
