Wiring

CAUTION

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. 5 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.

Fig. 6 shows the internal wiring schematic.

6.

Refer to Fig. 7 and 8 for typical 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.
