Grundfos Submersible Pumps with MS402 and MS4000 single phase, 3-wire,
PSC motors must be connected to mains via a motor capacitor that is
permanently connected during the operation. This type of motor does not
require the starting capacitor. It only requires the running capacitor. The ratings
of the capacitors are explained in the below table. Grundfos recommends using
only the capacitors as per the below mentioned ratings and the capacitor must
be installed as per the guidelines mentioned below.
Note: T
he warranty will be null & void if the suggested type, quality, and rating
of capacitor is not followed as mentioned below:
