• The setting of any thermal tripping that is fitted must correspond to the maxi-
mum current (see rating plate) of the speed stage at which the pump is being
operated.
Motor protection tripping devices
If Wilo tripping units SK 602(N)/SK 622(N) are present in existing systems,
pumps with full motor protection (WSK) can be connected to them. Establish
the mains connection and the tripping unit connection (observe rating plate
data) in accordance with the circuit diagram in fig. 7a:
