ELECTRICAL CONNECTION

This work must be carried out by a licensed electrician.

All 3 phase compressor are not supplied with a power lead or plug. A licensed electrician is required to wire up the

compressor from the wall mounted contactor box, to a dedicated 3 phase electrical outlet, either with a four pin plug or

hard-wired into the electrical supply. The circuit must be of adequate capacity and fitted with a circuit breaker.

Mount the contactor box to the wall as close to the compressor as practical.

Ensure correct direction of rotation

The installing electrician must ensure that when wired in, the motor

is turning in the correct direction. Failure to obtain the correct

direction of rotation will prevent the fan / flywheel from delivering

the necessary air cooling across the pump.

Electrical Connection

All electrical installation and service work must be performed by a licensed electrician in accordance with all applicable

regulations. The electric motor rating as shown on the motor nameplate and the power supply must have compatible

voltage, phase and frequency characteristics.

The required size of electrical wiring between the power supply and the electric motor varies according to motor power

and other factors, use the table below to understand what power is required to operate each size Compressor.

Adequately sized wiring must be installed to protect against excessive voltage drop during compressor start-up and

running. If connecting other electrical equipment to the same circuit, consider the total electrical load when selecting

the proper wire size. Overheating, short circuiting and fire damage may result from undersize wiring.

Portable electric generators are not recommended for operating compressors unless they have ample generating

capacity to provide the requisite starting and running currents without appreciable voltage or frequency drop.
