USE AND MAINTENANCE MANUAL - ELECTRICAL EQUIPMENT
The cable is to be entered into the electrical cabinet from the lower part and the connection via terminals L1-L2-L3
(three-phase voltage without neutral) and PE (earth conductor). The supply conductors must be firmly and securely
connected to the corresponding terminals of the equipment.
Certain models of electric control panel are equipped with IEC 309 (3P + PE) normalised plug for connection of the
electric power supply and the protection conductor; in these cases the user will have to provide for a power supply
line with respective female socket.
All the electrical connections (except for the electric power supply connection in the control panel models in which
the hook up of the line through normalised plug is foreseen) must be carried out through the lower side of the
enclosure of the control panel, executing appropriate holes in correspondence to the connection terminal blocks and
the disconnecting switch input terminals. Passage of the cables must happen through cable glands with IP
protection degree at least equal to that of the control panel. Any unused holes on the enclosure must be closed with
sealing caps.
The tools used when fastening the cables to the terminal blocks and/or to the terminals of the disconnecting switch
must be suitable for the shape and size of the fastening screws and the metal terminals and the relative housings
must not be damaged while fastening.
After having completed the wiring, all metal or plastic residuals must be removed from inside the enclosure (e.g.
screws, washers, lengths of wire or sheath, drilling chips, dust, pieces of paper, etc.) with a suction system.
ATTENTION
The eventual power supply socket-plug connection of the equipment must not be disconnected when in
charge.
The electricity must meet the following requisites:
 Three-phase voltage
 Rated frequency
 Efficient earthing system.
ATTENTION
The supply line of the equipment must be protected upstream against over voltage (e.g. atmospheric
discharge) and overcurrent (overloads or short-circuits), by installing suitable automatic circuit
breakers that are appropriately coordinated according to the electrical specifications and parameters of
the supply line. Particular consideration must be made to the short-circuit current where the equipment
is installed and to the short-circuit capacity of the equipment itself, indicated in the wiring diagram and
in Chapter 1 TECHNICAL DATA.
The equipment must not be live during the electrical connection. Therefore, the power supply line must
be disconnected upstream and the main switch must be locked in the open position with a padlock in
order to prevent the equipment from be started up unexpectedly. Before starting the connections
operations ensure that all the cables to be connected to the terminals of the equipment are not live.

The controls of the supplied equipment, on the front panel of the control panel, are an integral part of the
equipment. The functions of each push button or selector are clearly identified by a specific text label near the
device itself.
