Maintenance
WARNING: 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.
GENERATOR
As these systems are completely static, proceed as follow:
•
Periodic removal of accumulated dirt and dust from the inside
of the generator, using compressed air. Do not aim the air
jet directly onto the electrical components, in order to avoid
damaging them.
•
Make periodical inspections in order to individuate worn ca-
bles or loose connections that are the cause of overheating.
The pointing out of any difficulties
and their elimination
The supply line is attributed with the cause of the most com-
mon difficulties. In the case of breakdown, proceed as follows:
1) Check the value of the supply voltage.
2) Check that the power cable is perfectly 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 re-
pair of the generator, in case of breakdown we advise you to
contact skilled personnel or our technical service department.
