Fig. 10 Lead colors, example direct-online-starting (DOL) two
power cables
The use of 8 core and 11 core cables will be specified according
to sensor options. See pages 28-29.
For wiring diagrams, see Appendix on page 27:
Figure 1 shows direct-online-starting (DOL), one power cable.
Figure 2 shows direct-online-starting (DOL), two power cables.
Figure 3 shows direct-online-starting (DOL), three power cables.
Figure 4 shows star-delta starting (Y/D), one power cable.
8. Pump protection
KPL, KWM pumps are equipped with the following protective
switches and sensors. In the Factory Product Variant (FPV)
version, the sensors can be chosen individually.
(1)
Three Pt-100 sensors are mounted in the pump from factory,
but only one sensor is connected as standard. It is not
possible to connect all three stator thermal sensors, if bearing
sensors are also connected.
