10 Connecting this product to a power supply

The voltage selector is mounted in the switchplate at the rear of the pump, protected from water by the 520N module. The module must be removed to allow access to the switchplate. See 22.1 520N module fit- ting. 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 the mains supply.

Make suitable connection to an earthed single-phase mains electricity supply.

The voltage selector switch is not visible while the 520N module is in place. Do not swith the pump on unless you have checked that it is set to suit your power sup- ply by removing the module and inspecting the switch,

and then refitting the module. See 22.1 520N module fitting.

We recommend using commercially available supply voltage surge suppression where there is excessive electrical noise.

Power cable: The pump is supplied fitted with a cable gland and approximately 2.8m of power cable. Recommended cable: H05RN-F3G0.75; SJTW 105C 3- 18AWG; max OD 8mm (5/16in).

This drawing shows the cable connections from below with the interface card cover removed.

Power cables of NEMA 4X specification pumps are fitted with a standard US mains power plug. IP66 specification pumps are supplied with no plug. The colour code for the power cable is: brown - live; blue - neutral; green and yellow - earth.
