Wiring
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment circuitry.
Disconnect all power supplies before installation.
Motors with auxiliary switches can have more than one
disconnect.
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
1. Ensure that the voltage and frequency stamped on the
motor correspond with the power supply characteristics.
2. When connecting several motors in parallel, ensure that
the power supply VA rating is large enough to provide
power to all motors used without overloading.
3. Fig. 10 shows that motor terminals are quick-connects
located on top of the printed circuit board.
4. To access the wiring compartment:
a. Remove the four screws from the junction box top.
b. Lift off the cover.
5. Refer to Fig. 5 through 8 for wiring.
Wire the motor as follows:
1. Remove the wiring box cover by removing the four
screws holding the cover to the motor.
2. Wire motor to system using quick-connect terminals in
wiring box.
3. Replace wiring box cover.
