Before router installation begins, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router (for example, by causing a short circuit). |
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the router must be adequately grounded before power is connected. A pair of threaded inserts (PEM nuts) are provided on the right rear of the chassis for connecting the router to earth ground.

To ground the router, connect a grounding cable to earth ground and then attach it to the chassis grounding points. The grounding points are spaced at 0.625-in. (15.86-mm) centers. The accessory box shipped with the router includes the cable lug that attaches to the grounding cable (see Figure 28) and the UNC 1/4–20 screws (American) used to secure the grounding cable to the grounding points. (The cable lug shown in Figure 28 is also used for the DC power cables.) The grounding cable must be able to handle up to 82 A.
Figure 28: Power and Grounding Cable Lug
The grounding cable must be 8-AWG (8.4 m2) wire, minimum, or as permitted by the local code.
