1.4 Power Requirements
A schematic diagram for the electrical motor terminal connections is located in the junction box of the
motor or on the motor nameplate. Typical wirings for Three Phase Motors are as below:
The motor must be connected in accordance with electrical codes through a fused switch in order to
protect the motor against electrical or mechanical overload conditions. The overload of the motor starter
must be set at a level equal to the full load motor current listed on the motor nameplate.
If the pump is supplied with a motor starter, it should be preset at the according to customer
specifications. Please check that these settings are in line with the voltage at your location. If the voltage
is different, please contact Airtech for motor and starter information.
Correct direction of rotation is marked by an arrow on the motor fan housing and is counterclockwise
when looking at the motor from the motor's fan side.
After electrical connections have been made, the rotation of the motor should be checked. If it is
backwards, reverse any two of the three leads at the power connection.
Warning: Motors should only be installed by a qualified electrician, who has experience in wiring
three-phase motors. Improper electrical installation can cause injury or death.
Caution: VCX pumps must not be allowed to run backwards. The splash lubrication system is not
designed for backward operation and this may result in premature failure of the rotary claw
machine.
