Grounding Earth ground (subbase and
relay module).
1. Use to provide a connection between the subbase and
the control panel of the equipment. Earth ground must be
capable of conducting enough current to blow the 20A
fuse (or breaker) in the event of an internal short circuit.
2. Use wide straps or brackets to provide minimum length,
maximum surface area ground conductors. If a leadwire
must be used, use 14 AWG copper wire.
3. Make sure that mechanically tightened joints along the
ground path are free of nonconductive coatings and pro-
tected against corrosion on mating surfaces.
