3.7 Electrical installation: three-phase motors
3.7.1 Connect the pump to your electrical supply
CAUTION
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.
