Maintenance
ATTENTION:
Before carrying out any
inspection of the inside of the generator,
disconnect the system from the supply.
SPARE PARTS
Original spare parts have been specially
designed for our equipment. The use of
non-original spare parts may cause vari-
ations in performance or reduce the
foreseen level of safety.
We decline all responsibility for the use
of non-original spare parts.
THE GENERATOR
As these systems are completely static,
proceed as follow:
• Periodic removal of accumulated dirt
and dust from the inside of the gener-
ator, using compressed air. Do not aim
the air jet directly onto the electrical
components, in order to avoid damag-
ing them.
• Make periodical inspections in order to
individuate worn cables or loose con-
nections that are the cause of over-
heating.
The pointing out of
any difficulties and
their elimination
The supply line is attributed with the
cause of the most common difficul-
ties. In the case of breakdown, pro-
ceed as follows:
1)
Check the value of the supply vol-
tage;
2)
Check that the power cable is per-
fectly connected to the plug and the
supply switch;
3)
Check that the power fuses are not
burned out or loose;
4)
Check whether the following are
defective:
• the switch that supplies the
machine
• the plug socket in the wall
• the generator switch
NOTE:
Given the required technical
skills necessary for the repair of the
generator, in case of breakdown we
advise you to contact skilled personnel
or our technical service department.
