1.1 - Warnings and tips

Before proceeding with the installation this manual should be read carefully, because the guarantee
is automatically cancelled in the event of negligence, incorrect manoeuvre or improper use or if
unauthorised people tamper with the circuit.
Moreover it is cancelled when the fault is due to strong accidental overvoltages on the power
supply network. Thus if the Control Unit is installed in a place which is subject to violent
atmospheric discharges (storms), suitable protection must be installed on the power supply line
and it must be connected to the earth as rigorously as possible and respecting IEC standards.
