22 Automatic control wiring

Interfacing the pump with other devices is by means of screw-terminal connectors within the 520N watertight module at the rear of the pump. Suitable cable must be passed into the module through one or more watertight cable glands and connect- ed appropriately. The module must be removed to allow this.

It is important to check the pump’s voltage setting to ensure that it matches the supply. The voltage selec- tion switch is on the rear panel of the drive. The module must be removed (and replaced) to allow it to be checked.

22.1520N module removal and replacement

To remove the 520N watertight module:

The module is secured to the back of the drive unit by six M5x12 Pozidriv counter- sunk stainless steel screws.

￿Remove the six screws using a suitable crosspoint screwdriver, leaving the top centre screw till last. Even when all screws have been removed, the sealing strip may cause the module to adhere to the drive. If so, a gentle tap will free it. Do not use a tool to lever it off.

￿The sealing strip should be retained within its channel on the face of the mod- ule. The transparent on/off switch cover should be retained on its flange on the face of the module. Check the integrity of the seal and the transparent on/off switch cover. If either is damaged, it must be renewed to maintain ingress pro- tection.
