3.2.- INSTALLATION
The unit is installed on a DIN rail.
All active conductors that supply the loads or the part of the installation where the earth leak-
age protection with this unit is required must pass through the sensor associated with the unit.
The unit must be mounted inside an electric panel.
Likewise, it must be connected to a fuse-protected power circuit, in accordance with its power
supply range and consumption. In turn, the power circuit must be fitted with a circuit breaker
switch or an equivalent device, in order to be able to disconnect the unit from the power supply
mains.
Note:
The connection diagram suggests a cable section of 1- 1.5 mm.
Recommended torque 0.5-0.6 Nm.
Terminals, opening covers or removing elements can expose parts that are haz-
ardous to the touch while the unit is powered
