5.3 Electrical Connections
Use power cables of the appropriate cross-
section for the rated currents of the electrical
components (see section 5.2).
Ensure that the supply voltage (V, Hz) is as
stated on the data plate. Install a differential
magnetothermal switch upstream of the
equipment. Protect the motor from
overcurrents by means of a motor protector
switch with suitable electrical characteristics.
On all versions with a fan, it is possible to vary
the flow rate of air treated by the cooler by
interfacing the motor with an external speed
regulation device (inverter). For connection,
refer to the inverter's technical
documentation.
Ensure that all electrical connections have
been made according to the
instructions in this manual, are well
insulated and comply with current
regulations. Power cables must be
replaced by the manufacturer, his technical
service department or otherwise by a qualified
