Some units prior to the design of the ACT may require specific parameter settings, and these are
not reported in the supplied manuals. For these requirements, our AFTERSALES department is
ready to provide the necessary assistance.
CAUTION: The electrical wiring to the terminal blocks has to be done only by qualified personnel.
The power supply has to respect the listed limits: failing this, the warranty will terminate
immediately. Before beginning any type of operation, make sure that power is disconnected.
Connect the conductors in order: phase, neutral and earth.
The supply voltage’s fluctuations cannot exceed ±10% of the nominal value. If this tolerance
should not be respected, please contact our technical department.
Install upstream of each unit a suitable protective device and power disconnector, with delayed
characteristic curve, with at least 3 mm contact opening and adequate breaking capacity and
residual current protection.
Effective earthing is mandatory; the manufacturer is not responsible for damage caused in case
of lack thereof.
Use cables that meet the regulations in force in the different countries.
