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 electrical devices that
may generate mains-borne noise, for example 3-phase contactors and inductive heaters.
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.
Only use with supplied power cable.
The pump must be positioned so that the disconnection device is easily
accessible when the equipment is in use.
IP66 pumps are supplied with a mains plug. The gland at the NEMA Module
end of the cable is IP66 rated. The mains plug at the opposite end of the
cable is NOT IP66 rated. It is your responsibility to ensure that the connection
to the mains supply is IP66 rated.
