3.5.2 Motor connection
Refer to the wiring instructions provided with the pump motor. Configure electrical
connections according to the manufacturer’s instructions.
WARNING
A suitable crimping card must be installed on the power supply cable.
Otherwise, the cable (or cable core) may be disconnected from the pump
and there may a risk of injury or death from electric shock.
WARNING
Ensure that the pump can be isolated and locked out from the power supply.
The motor must be correctly configured and the power connections must be
correct. If not, the motor can be damaged.
WARNING
When the motor is connected to the power supply, the motor power supply
is automatically cut off when the backing pump is stopped. Otherwise, if the
motor continues to run when the backing pump is stopped, the pump will
overheat.
WARNING
Connect the power supply to the motor through a contactor which has a
manual reset control.
It should be connected to the power supply via a contactor with overload protection, or use a
controller with a contactor.
The user must use a contactor with a manual reset control. Otherwise, the pump will
automatically restart after a circuit overload or power supply failure.
Use a suitable multi-wire cable and a suitable cable gland to connect the power supply to the
pump motor.
Connect the motor and power supply as follows:
1. Remove the motor terminal box cover.
