INSTALLATION
1) Fix Power Reducer onto the wall.
LOCATION: install Power Reducer next to the wire that supplies power to the resisitive load
(immersion). They will share the same power supply!
3) Cut the resistive load power supply cable and connect the pins
to the correct terminals.
WARNING: before cutting the cable, make sure the power to the immersion is OFF
towards the immersion
towards the power supply
2) Install the Current Transformer

a) Remove the cover unwscrewing the 4 screws on the front of Power Reducer.
b) Drill the wall according to the 4 holes at the back of the device.
c) Securely mount the device on the wall using appropriate screws
VENTILATION: install the device vertically (cable glands must be placed DOWNWARDS).
Proper ventilation is also guaranteed by clearings around the device. Make sure no other ob-
jects are placed within a range of 7 centimeteres.
16 A
Power Supply cables must be tripolar. Each single wire must feature a minimum
dimension of 2.5 mm2

4) Switch on Power Reducer and verify the correct operation mode
!Warning: do not use Power Reducer itself as a template for drilling holes directly on
the wall.

Possible measurements made with amperometric clamps must be detected on the Live-phase
that connects the power source with the Power Reducer. Measurements detected on the wire
directed towards the resistive load will be inaccurate.

b) position the Current Transformer
WARNING: pay ATTENTION that CT is actually orientated in the right direction and that it clamps
the Live-phase wire that connects the RESIDUAL CURRENT CIRCUIT-BREAKER to the Mains
meter (GRID). Make sure the Current Transformer is NOT clamped on the Live-phase that con-
nects the residual curent circuit-braker to the household.
5) Wire the clean contact for system bypass switch (optional)
When the Clean Contact is CLOSED, Power Reducer is bypassed: the load is always working

Installation successfully
completed
Power Reducer is working in
“0-10V mode”: the device does
not detect any voltage variation
out of the CT
Possible causes: CT wires not
connected; OR no electricity
detected out of the CT.
Check the correct installation /
wiring of the CT.
ERROR !
Verify the correct installation of
the Power Reducer, checking:
- CT orientation,
- which cable is clamped by the CT,
- the sequence of colours / wires,
- the connections between termi-
nals TA+ and TA- on the Power
Reducer side
