The grounding lug must be NRTL listed and compatible with copper conductors. Only copper conductors 
(wires) must be used and the copper conductor must comply with National Electrical Code (NEC) for 
ampacity. 

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

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

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

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

Remove the adhesive label from either the right or left grounding pad on the chassis.

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.

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

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

Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly 
handled and can result in complete or intermittent failures.

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Connect 
the strap to one of the following:

ESD wrist strap connector (see 

 for the connector location)

Any unpainted surface on the chassis

Periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 
10 megohms (Mohms).
