The wiring of Power Reducer is composed of 2 distinct areas: "supply" connections and "control" connections
5.3 Wiring the supply connections
The power supply is carried by the same cable that feeds the load itself. Cut the cable of the immersion
(or replace the old cable with a new one) so that the two ends can be connected to terminals 1 and 3 of
Power Reducer, as shown below.

!
WARNING: before you cut the immersion cable, make sure it is switched OFF.
!
WARNING: the power supply cable must be a three-core cable. Each single wire must have a minumum cross
section of 2,5 mm
WARNING: protect the cable that supplies the Power Reducer with a 16A circuit breaker or with an appropriate fuse
!
!
WARNING:
possible measurements made with amperometric clamps must be detected on the live-phase cable that
connects the power source to the Power Reducer. Measurements detected on the wire directed towards
the resistive load (immersion) will be inaccurate, due to the influence generated by high-frequency
energy modulation signals.
