Reading the fault list archives
To guarantee correct operation of the system all its components must be correctly matched up. Incorrect
operation leads to lower yields with a subsequent reduction in system profitability.
The inverter includes functions to warn the user of failures or faults affecting the system. Periodical checks
of system operation are in any case still necessary for the detection of minor operating faults which are not
associated with an alarm. The inverter’s alarm memory and the data stored in the Data Logger (if installed)
must be analysed at least once a month. To do this, proceed as described in the Programming Guide.

Checking the external and internal conditions
To check the external/internal conditions of the electrical cabinet, proceed as follows:
OVERALL CONDITION OF THE CABINET
•
Check the external condition of the cabinet.
•
Check the state of the isolating sheaths on the conductors.
•
Check that there are no signs of overheating on the power conductors (especially near the connection
points on the equipment).
•
Check that there are no signs of cable gnawing caused by rodents.
•
Check the state of all the signs/nameplates affixed to the equipment. Signs must always be in good
condition and legible.
GENERAL CABINET CLEANING
•
Check the interior of the cabinet for the build-up of dust, dirt, humidity and infiltration of water from
the outside.
•
Check that the ventilation ducts on the inductors and transformers are clear.
