Grounding the Chassis
Warning
Statement 1024 Ground Conductor
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is available.
Warning Statement 1046 Installing or Replacing the Unit
To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be
made first and disconnected last.
Before you begin
Before you can ground the chassis, you must have a connection to the earth ground for the data center building.
Step 1
Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding
wire. We recommend 6-AWG wire for the U.S. installations.
Step 2
Insert the stripped end of the grounding wire into the open end of the grounding lug. Use a crimping tool to crimp the
lug to the wire, see the following figure. Verify that the ground wire is securely attached to the grounding lug by attempting
to pull the wire out of the crimped lug.

Step 3
Secure the grounding lug to the chassis grounding pad with two M4 screws, see the previous figure. Tighten the screws
to 11 to 15 in-lb (1.24 to 1.69 N·m) of torque.
