Grounding the chassis is required, even if the rack is already grounded. A grounding pad with two threaded
holes is provided on the chassis for attaching either a grounding lug or grounding cover plate. 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.
Caution
When terminating the frame ground, do not use soldering lug connectors, screwless (push-in) connectors,
quick connect connectors, or other friction-fit connectors.
Caution
Step 1
Verify that the office ground cable is connected to the top of the rack and the office ground, according to local site
practice.
