J4350 and J6350 Services Router Getting Started Guide
Chassis Grounding
To meet safety and electromagnetic interference (EMI) requirements and to
ensure proper
operation, the Services Router must be adequately grounded
before power is connected. In addition to the grounding pin on the AC p ower
plug cord, a threaded insert (PEM nut), screw, a nd washer are provided on
the rear of th

CAUTION: Before router installation begins, a licensed electrician must attach a
cable lug to th
e 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).
The grounding cables must be 14 AWG single-strand wire cable, and
must be able t
o handle amperage up to 20 A.
Each groundi
ng lug must be a ring-type, vinyl-insulated TV14-6R lug, or
equivalent, to accommodate the 14 AWG cable.
