VERIFICATIONS PRIOR TO INSTALLATION
The following must be complied with in order to prevent any type of problem when commissioning the equipment.
WARNINGS
 Before connecting the equipment ensure that power distribution network data corresponds with the data
on the plates. The installation must be carried out in compliance with the applicable regulations in
accordance with the manufacturer guidelines and by qualified electricians. Incorrect installation can
cause damage to persons or objects for which the manufacturer cannot be held liable.
 The electrical safety of this equipment is only guaranteed when it is connected correctly to an effective
earthing system, implemented according to the applicable electrical safety regulations. The manufacturer
cannot be held liable for any damage caused due to no earthing system being installed and if the
electrical equipment is installed in an electrical distribution system with an earthing system other than
that described in Chapter 1.2 GENERAL TECHNICAL DATA.
 This basic safety requirement must be verified and if in doubt, ask professionally qualified personnel to
perform an accurate inspection of the system.
The equipment must not be installed:

where paints or solvents are stored;

rooms with operations that may create flammable or explosive environments;

near heat sources or flammable substances.
ELECTRICAL CONNECTION
The equipment must be connected to the electrical power supply line, considering the following:

The Laws and technical regulations applicable in the place and at the time of the installation.

The data shown on the technical documentation and on the plate.
The cross-sections of the cables are to be calculated considering the maximum current absorbed and the position of
the electrical power supply line.
WARNINGS

The main power supply line must consist of wires with an adequate cross section, sized according to the data in
the technical documentation. In particular, the section of the conductors must comply with the length of the
supply line and the relative voltage drop. It must also comply with the derating of the cables if these are laid in
bundle or in layers with other existing channeled wires. The Customer is responsible for these details that affect
the sizing, conditions and types of installation.

The Customer must provide over current protection (overloads and short-circuits) of the electrical power line.
Disconnecting devices locked in the open position must be installed upstream on the power line.

The equipment must be connected to an effective earthing system.
