When used for marine applications, please use standard
installation cables with concentric conductors for earth. This
earth conductor shall be 360 degree connected to earth in
the cable glands or in the near of the gland.
Warning!
Capacitors for power factor compensation are not allowed
in between the softstarter and the motor, since this can
cause current peaks which can burn the thyristors in the
softstarter. If such capacitors are to be used, they should be
connected on the line side of the softstarter.
