Connecting to a power supply
A well regulated electrical mains supply is required along with cable connections
conforming to the best practice of noise immunity. It is not recommended to site these
drives alongside 'dirty' electrical mains devices, such as 3-phase contactors and inductive
heaters without special attention being paid to mains-borne noise.
Set the voltage selector to 115V for 100-120V 50/60Hz supplies or
230V for 200-240V 50/60Hz supplies. Always check the voltage
selector switch before connecting to the mains supply or the pump will
be damaged.
Make suitable connection to an earthed single-phase mains
electricity supply.
If the pump type is one with an 'N' module, the voltage selector is not visible
while the module is in place. It is mounted in the switch plate at the rear of the
pump, protected from water by the 'N' module. The module must be removed to
allow access to the switch plate. Do not switch the pump on unless you have
checked that it is set to suit your power supply by removing the module and
inspecting the switch and then refitting the module.

We recommend using a commercially available supply voltage surge
suppression where there is excessive electrical noise.
Ensure that all power supply cables are adequately rated for the
equipment.
The pump must be positioned so that the disconnection device is
easily accessible when the equipment is in use.
