3.6 Electrical installation: single-phase motors
3.6.1 Introduction
Note: The pump will restart automatically when the electrical supply is restored after an interruption and when
the pump cools after it has overheated. If you do not want the pump to restart automatically, use electrical
control equipment which must be reset manually.
Ensure that your electrical supply voltage corresponds with the voltage specified on the motor data plate.
Table 5 gives the recommended fuse rating, and Table 8 specifies the Figure which identifies the correct
electrical supply connection details.
The diameter of the outer sheath of the electrical supply cable must be within the range 7 to 10.5 mm.
The cable must conform in size and colour coding with your local and national electrical installation
regulations. The temperature rating of the cable must be 70
o
C or greater.
WARNING
Ensure that the electrical installation of the pump conforms with your local and national
safety requirements. It must be connected to a suitably fused and protected electrical
supply and a suitable earth (ground) point.
CAUTION
Ensure that the motor is correctly configured for your electrical supply voltage and frequency. If you
do not, you can damage the motor.
