Motor Wiring
See the
System Wiring Schematics
on pages 10 and

Install an explosion-proof seal fitting in the wall separat-
ing the hazardous area from the non-hazardous area.
Use explosion-proof conduit or increased safety protec-
tion concepts to run wires between the motor junction
box and the variable frequency drive (VFD).
Use 14 gauge wire (3 wires plus ground) to connect the
VFD and the motor.
Use 18 gauge wire between pins 8 and 11 on the VFD
and the motor overtemperature switch.
Motor must be wired to rotate fan counter-clockwise
when viewed from fan end of motor. See F
IG

Improper wiring may cause electric shock or other
serious injury if work is not performed properly. Have
a qualified electrician perform any electrical work. Be
sure your installation complies with all National,
State and Local safety and fire codes.
