LECTRICAL CONNECTION
The electrical connection must be carried out exclusively by
a specialised technician according to EN 60 204.1 (IEC
204.01) regulations
The generating sets are supplied already set-up for connection
to the user.
The function of the generating set is to substitute the mains
electricity supply, and as such, must be considered as an
external source of energy. In the execution of the connections
must be respected the suitable connections in the wiring
diagram furnished with the group.

ABLE SIZES
The choice and size of cables to use is the responsibility
of the plant installer.
It should be emphasised that using smaller sections
than that recommended will cause excessive voltage
drops and lead to dangerous overheating of the wiring.
3.6.2 P
OWER CABLE LAYNG
All set-user connecting cables on manual sets must be
laid in suitable channels or ducts.
3.6.3 E
ARTHING
Metal parts of the plant with which people can come into
physical contact and which, due to an insulation fault or
other reasons, may become live, must be connected to
an earthing system.
The generating’sets mounted on bases and control
panels are equipped with an earth terminal.
The sizing of the earth wires to the earthing system and
the relative contact resistance must comply with current
laws and standards.
The manufacturer is NOT responsible for any damage
caused by failure to earth the system.
The earthing system must be located as far as possible
from railway/tram lines in order to prevent electro-
corrosion of the internal components of the engine
in contact with water.
Do not tamper with the active protections, thermal
switches and differential magnetothermal switches.
• In the event of malfunctioning, do not remove the
panel to attempt repairing it. Contact
ma s e
specialised personnel.
• Take the necessary precautions to prevent the
danger of electrocution; check that the earthing
system has been installed and constructed in
accordance with regulations.
• For the safety of the users, the earth connection of
the generator must always be carried out paying
particular attention to the cable cross-section used.
For the connection of the earth cable use the
dedicated terminal on the generator.
The manufacturer is not responsible for any damage
caused by failure to earth the system.
