When laying the ducting for routing the electrical
cables and for the cable entry point into the
control unit housing, check that there are no water
deposits in the junction wells nor condensate in the
connection ducts, as water and damp conditions
could damage the product’s electronic circuits.
3.5 INSTALLING THE CONTROL UNIT

Secure the control unit to an unmovable, vertical,
flat surface adequately protected against possible
impacts. The lower part of the control unit must be
at least 40 cm above the ground.
