Safety precautions for
maintenance
WARNING
Before performing any maintenance,
turn the selector switch with the
removable key to the "OFF" position
and disconnect the battery. This
prevents the generator from being
activated unexpectedly.
WARNING
Prevent risks of an electrical nature
by disconnecting the power from the
board
before
maintenance
by
specific key selector, isolating both
the main disconnecting switch (CP.1)
and the load disconnecting switch
and disconnecting the battery.

General checks on the
electrical system
Verify there is no water or condensation

Make sure there is absolutely no water infiltration
•
or the formation of hazardous condensation.
Promptly check the sealing systems (gaskets).
•
Immediately remove water and perform the

necessary repairs.
Verify the tightness of the cables and
components
Check the tightness of the power cables and
•
connection bars.
Check the tightness of the clamps and wires on
•
the terminal boards by pulling the cables lightly.
Check the tightness of all the fixing screws of the
•
components, both in the control board and on the
generator.
Tighten the screws when necessary.
