3-3 Power Supply and Wiring
Cooling coil assemblies with air handling systems are standard
230/- and 460/3/60 voltage. Optional voltages are available. You
must know the electrical power of the proper voltage, phase and
cycle to match the electrical data listed on the blower motor
nameplate. Voltage must be within 10% of the motor nameplate
voltage during operation.
Note: Check blower rotation for proper direction.
