3.6Motor Wiring

3.6.1Single-Phase Motors - IMPORTANT!

Single phase three-wire motors require the use of a special controller includ- ed in a separate enclosure with each motor. The controller enclosure is not attached to the motor. Operation of motors without the controller or using the incorrect controller can result in failure of the motor and voids warranty.

The controller is mounted in a NEMA 4X enclosure and suitable for indoor or outdoor applications within temperatures of 14°F (-10°C) to 122°F (50°C).

The controller should never be mounted in direct sunlight or high-temperature locations as this will cause shortened capacitor life and unnecessary tripping of the overload protector.

The controller enclosure is designed for vertical upright mounting only. Mounting in other positions will affect its operation.

The controller must be electrically wired to the motor using minimum 8 AWG for 5 horsepower motors and 10 AWG for 3 horsepower motors.

Two Sources of Power to

the Single-Phase Controller

The controller must be supplied with two sources of power. The control circuit (motor starter coil) must be electrically wired with 110 VAC-50 Hz or 120 VAC- 60 Hz voltage. The power circuit must be electrically wired with single-phase to match the motor label.
