ELECTRICAL CONNECTION

Check that the information on the nameplate corresponds to the power supply.
Employ a competent electrician to ensure wiring installation is made in accordance with any local
electrical codes. Every motor requires either a fused disconnect switch or a circuit breaker.
A SINGLE PHASE MOTOR has a built in thermal overload switch.

THREE PHASE MOTOR

THREE PHASE MOTORS requires a starter switch or magnetic starter with correctly sized overload
protection in addition to the fused disconnect switch.
CHECK THE ROTATION OF THREE PHASE MOTORS.
The motor is only suitable for clockwise operation when viewed from the motor end fan (cowl) cover.
Three phase motors could rotate in either direction. Changing any 2 wires of the cable on a three
phase motor will reverse the direction of rotation. To check the rotation of the motor, turn on for
approximately 1 second. If it is running in the wrong direction turn off power and interchanging any 2
wires and repeat the above step to check.
When installing three phase pumps a separate device must be available for permanent installation,
this is so the pump can be isolated from the mains power. A contact distance of 3mm per pole is
required for both three phase and single phase units.
Motor protection MUST be installed corresponding to the nominal current of the motor. SEE VALUE
ON RATING PLATE.
It is the RESPONSIBILITY of the user to ensure adequate protection between the motor and the
power supply.
The installer must protect all three phases on the supply of the motor so that the pump cannot run
on 1 or 2 phases only.
!
WARNING
Before disconnecting electrical connections, shut of the electricity at its source:
EXAMPLE : The fuse or circuit breaker box. Before work is carried out on the pump ensure the pump
switch or timers are turned off and MAKE CERTAIN THE MAINS POWER IS SWITCHED OFF.
