3.5 Electrical installation
WARNING
Ensure that the electrical installation of the DP180 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.
3.5.1 Select high or low voltage operation
The universal voltage and frequency motor can be configured for low voltage operation
(200/220-240 V at 50 Hz or 208-230 V at 60 Hz) or for high voltage operation (415 V at 50 Hz, 380 V
at 50/60 Hz, or 460 V at 60 Hz).
Figures 5 to 8 show the required wiring configurations for the electrical supply voltages and
frequencies as shown in Table 3.

Table 3 - Pump-motor terminal-box wiring configurations
Use the following procedure to configure the pump for use with your electrical supply:
1. Check the information on the pump-motor data plate to make sure that the pump is suitable
for use with your electrical supply voltage and frequency. If the pump is not suitable, do not
continue to install it.
2. Remove the cover from the pump-motor terminal-box.
3. Check the configuration of the links in the motor terminal-box. If necessary, change the
configuration to suit your electrical supply voltage and frequency (see Figures 5 to 8).
