Electrical Connection
Check that the information on the name plate corresponds to the power supply.
Employ a licensed 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 Motors
Three phase motors require 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 interchange 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 off 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
.
