Electrical installation: three-phase motors
3.7.1
Connect the pump to your electrical supply
Ensure that the electrical installation of your pump-motor conforms with your local and national
safety requirements. It must be connected to a suitably fused and protected electrical supply and
a suitable earth point.
If your pump-motor can be used with more than one voltage range, you must ensure that the motor is configured
for your electrical supply voltage. If you do not, you may damage the motor.
Note:
The pump will restart automatically when the electrical supply is restored after an interruption. If you do
not want the pump to restart automatically, use electrical control equipment which must be reset
manually.
