4-noks Power Reducer SA Quick Manual

INSTALLATION
1) Fix Power Reducer onto the wall.
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
!
Warning: do not use Power Reducer itself as a template for drilling holes directly on
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!
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.
2) Install the Current Transformer
a) connect the Current Transformer to the Power Reducer terminals

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.

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
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.
Power Supply cables must be tripolar. Each single wire must feature a minimum
dimension of 2.5 mm
Installation of 16 A thermal magnetic to protect the device
4) Switch on Power Reducer and verify the correct operation mode
