1. Remove nut (1) and lockwasher (2) from nearest mast base (3) to ground point.
2. Install ground wire (4), lockwasher (2), and nut (1) to mast base (3).
Connection of ground wire depends on availability of good ground connection such as a
water pipe (5) or a driven ground rod (6). For a more detailed description of grounding
requirements, refer to TB 43-0125.
If ground wire is to be connected to a water pipe with a meter, ground wire must be
connected to inlet side. If inlet side is not readily accessible, connect ground wire to
outlet side and connect a jumper wire from outlet to inlet side. Failure to use a jumper
wire may cause damage to meter.
