Grounding the Router
Before you connect the power input cable to an E4G-200 series router, you must ground the router,
following the instructions in this section.
A grounding lug is located on the front of the router (Figure 19). You can move the lug to the back
panel (Figure 19) if this location is more suitable for your installation site.

WARNING!
Connect the ground wire before you connect any power cables.
To ground the router:
1 If necessary, move the grounding lug to the back panel of the router.
2 At one end of the ground wire, strip the insulation to expose 1/2 inch (12 mm) of bare wire.
3 Loosen the screw, and insert the stripped wire into the grounding lug (Figure 20).
4 Using a 1/4-inch straight-tip torque screwdriver, tighten the retaining screw to 20 pound-inches
(2.25 Newton-meters).
