• 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. Perform the
mains connection and also the tripping unit connection (refer to the rating plate
data) in accordance with the circuit diagram fig. 7a:
1~230 V: 320 W ≤ P
7.2.2 Frequency converter operation
Three-phase motors of the series TOP-S/-SD/-I can be connected to a fre-
quency converter. When operating with frequency converters, output filters
should be used to reduce noise and to avoid damage due to voltage spikes.
