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).
