3.6.2 P
OWER
CABLE
CONNECTION
The set of generator-utility-network connection cables
must be properly arranged in a suitable duct or underground
passage (also see para 3.7/3.8).
For installation, use the following procedure:
1) Remove the small panel (ref.1).
2) Fit the cables inside the panel (ref.1), through the
gasket (ref.4), as far as the power terminal board
(ref.5).
3) Clamp with specific cable retainers.
4) Connect the power cables to the respective terminals
indicated by the icons.
3.6.3 G
ROUND
CONNECTION
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 a
ground system.
To connect to ground, use the procedure given in par.3.6.2,
then connect the ground cable to the respective terminal
indicated by the icon (ref.6).
The sizing of the ground wires to the ground system and the
relative contact resistance must comply with current laws
and standards.
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 Mase 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.
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.
