Connecting the T4000 Grounding Cable
You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis grounding points with two screws. You must provide the grounding cable (a cable lug is supplied with the router). To connect the grounding cable (see Figure 1):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
- Make sure that grounding surfaces are clean and brought to a bright finish before grounding connections are made.
- Connect the grounding cable to a proper earth ground.
- Verify that a licensed electrician has attached the cable lug provided with the router to the grounding cable.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Place the grounding cable lug over the grounding points. The left pair is sized for M6 screws, and the right pair is sized for UNC 1/4-20 screws.
- Secure the grounding cable lug to the grounding points, first with the washers, then with the screws.
- Verify that the grounding cabling is correct, that the grounding cable does not touch or block access to router components, and that it does not drape where people could trip on it.
