Grounding the Chassis

Warning

This equipment must be grounded. 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.

Statement 1024

Warning

During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the

backplane with your hand or any metal tool, or you could shock yourself.

Statement 94

You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical

safety standards. For NEBS-compliant grounding, use size 6 AWG (13 mm

) copper wire and the ground lug provided in the

accessory kit.

Note This equipment is suitable for installation in Network Telecommunications Facilities and locations where the NEC

applies. The equipment is suitable for installation as part of the Common Bonding Network (CBN).

To connect the chassis to a reliable earth ground, perform the following steps:

Step 1 Strip one end of the ground wire to the length required for the ground lug or terminal (about 0.75 in. [20 mm] for the

NEBS ground lug).

Step 2 Crimp the ground wire to the ground lug, using a crimp tool of the appropriate size.

Step 3 Attach the ground lug to the chassis as shown in Figure 10 and Figure 11. Tighten the screws to a torque of 8 to 10

in-lb (0.9 to 1.1 N-m).

Step 4 Connect the other end of the ground wire to a suitable grounding point at your site.
