Electrical Connection
Weathertight Models: Interrupt electrical power. Remove the top cover plate. Terminal
block is standard. The insulation is marked C - Common, NO - Normally Open,
NC - Normally Closed and G - Ground (earth) when applicable.
Explosion-Proof Models: Hermetically sealed switching element capsule has 18”,
18-AWG wire leads color coded and marked C - Common, NO - Normally Open,
NC - Normally Closed and G - Ground (earth) when applicable. (See schematic.)
Ensure that the wiring conforms to all applicable local and national electrical codes and
