Fig. 11: Wiring of the electrode relay: a) Connection diagram, b) Position of the
electrode in the motor housing
An electrode (B2) fitted inside the motor monitors the winding space for leakage.
The electrode is intended for connection to an electrode relay (core marking 9).
Tripping of the electrode relay must result in the pump set cutting out.
Every time the relay trips the pump set, the pump set needs to be inspected and its
insulation resistance measured.
The electrode relay (K1) must trip the motor at a tripping resistance between 3 and
60 kΩ.
