3.7 Electrical installation: three-phase pumps
3.7.1 Check and configure the motor
Ensure that the motor is configured correctly for your electrical supply. If you operate the pump when the motor
is not configured correctly for the electrical supply, you will damage the motor.
Power cable rated at 70 °C must be used to connect the 3 phase pump to the power supply. Failure to do so may
result in cable damage if the pump is used in high ambient temperatures.
1. Place the pump on its back, exposing the underside of the pump (refer to Figure 5). Undo the 3 screws securing
the access plate and remove it.
2. Ensure that the motor is correctly configured for your electrical supply. If necessary reconfigure the links (refer
to Figures 6 and 7) to suit your electrical supply.
For 200 - 230 V electrical supplies the links must be configured as shown in Figure 6.
For 380 - 460 V electrical supplies the links must be configured as shown in Figure 7.
3.7.2 Connect the pump to your electrical supply
Notes: 1. To prevent automatic restart of the pump-motor if the electrical supply is restored after an electrical
supply failure, connect the pump to the electrical supply through suitable control equipment which
must be reset manually after an electrical supply failure.
2. To maintain compliance with CSA (Canadian Standards Association) standards, you must incorporate a
switch or circuit breaker in the pump electrical supply. The switch or circuit breaker must be close to
the pump and easily accessible, and must be clearly marked to identify that it is the electrical supply
disconnection device for the pump.
We recommend that you connect the electrical supply to the motor through a starter or circuit breaker which has
thermal over-current protection which can be adjusted to suit the current ratings shown in Table 6. The fuse ratings
in Table 6 are provided for guidance only. The supplier of your thermal over-current protection device may specify
different values to ensure correct operation of the fuse and the over-current protection device.
Ensure that the electrical installation of the XDS 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 point.
If the pump is to be used on the floor of a work area, position the power lead and the exhaust and
inlet hoses with care. Ensure that personnel in the area are aware of any obstructions around the
pump.
The electrical supply cable to the 3-phase pump is permanently attached to the pump. Ensure that
it is routed such that it cannot be snagged or become a tripping hazard.
