Installation and user manual
EN 1 SAFETY WARNING
During installation and operation of the device, it is neces-
sary to comply with the following instructions:
1) The device must be installed by a skilled person, in strict
compliance with the connection diagrams.
2) Do not power on or connect the device if any part of it is
damaged.
3) After installation, inaccessibility to the connection termi-
nals without appropriate tools must be granted.
4) The device must be installed and activated in compliance
with current electric systems standards.
5) Before accessing the connection terminals, verify that the
leads are not live.

Use cable size 0,75 - 1,5 mm2for solid core cable. For the cable supply cable use cable type H05VV-F 3x0,75mm2.
The wires lenghtsshould be measured according to the distance of the terminals from the cable clamp.
After fixing the wires in the relative terminals, screw the screws of the cable clamp to lock the cable. Insert the grommet
plug into the hole
