2. Protection against overheating

When fitted with a basic module, the pump can be connected directly to an
external mains switch, as the built-in thermal overload switch will protect the
pump against overheating at all three speeds.
If the pump has been cut out by the thermal overload switch, it will restart au-
tomatically when it has cooled to normal temperature.
3. Input for external start/stop
The basic module enables the connection of an external on/off switch across
terminals 7 and 8.
4. Fitting
Before removing the terminal box cover, make sure that the elec-
tricity supply has been switched off and that it cannot be acciden-
tally switched on.
1. Switch off the electricity supply to the pump by means of the external
mains switch. The green indicator light in the window of the terminal box
cover must be off.
2. Remove the terminal box cover.
3. Remove all wires from the terminal block.
4. Replace the existing module in the terminal box by the basic module, see
fig. 1. For removal/fitting of the three screws shown, use the screwdriver
supplied with the module.
