INSTALLATION
WIRING
Disconnect power supply before beginning wiring to
prevent electrical shock or equipment damage. All wir-
ing must comply with applicable local codes, ordi-
nances, and regulations.
Make sure that the voltage and frequency stamped on
the motor correspond to the characteristics of the power
supply. When several motors are to be connected in paral-
lel, make sure that the power supply VA rating is large
enough to provide power to all the motors to be used
without overloading. An integral transformer is used to
supply 24 Vac power to the motor. Make sure that the
power requirements stamped on the motor correspond to
the characteristics of the power supply.
The motor terminals are quick-connects located on top
of the printed circuit wiring board inside the wiring com-
partment. Access to the wiring compartment is gained by
removing the four screws on the top of the wiring box and
lifting off the cover. See Fig. 5 for terminal locations. See
Fig. 6 for the internal schematic. Fig. 7 shows connections
for typical system applications. Fig. 8 shows parallel
motor connections.
