WIRING
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply before installation.
IMPORTANT
All wiring must agree with applicable codes, ordi-
nances and regulations.
1.
Ensure that the voltage and frequency stamped on the
motor correspond to 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. 11 shows that the 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 for typical wiring, and Fig. 7 for internal
auxiliary switch connections.
NOTE: Reverse motor rotation by switching wires at
either the motor or the panel. Reverse rotation on
the Series 90 models by reversing the wires at ter-
minals W and B.
