9. MAINTENANCE
9.1 Ordinary and extraordinary maintenance
Premise
The information in this paragraph is given in compliance with CEI EN 61439-1 prf. 6.2.2.
Maintenance and repair must be carried out by SPECIALIZED personnel and "TRAINED PERSONS". Maintenance
and repair that are not carried out properly can be a source of serious danger to the user.
Before starting maintenance and repair operations, carefully read the instructions in this Technical Manual to avoid
damage to people, pets and property.
Regular maintenance ensures the equipment level of safety and perfect initial operation.
Operator safety
It is essential that the persons in charge of maintenance are professionally qualified and follow normal safety
procedures.
Incorrect maintenance can cause damage to persons or property, for which the manufacturer can not be held
responsible.
The automatic rephasing device is equipped with an operating element, so it is necessary to disconnect all the
capacitor batteries before disconnecting the panel from the mains.
WARNING! Before accessing the appliance, wait at least three minutes after having disconnected the voltage, then
short-circuiting and grounding all the capacitors (CEI EN 60831-1 / prf.22 standard).
Avoid disconnecting a battery and re-insert it manually, in a shorter time than 30 s necessary for the discharge of
the capacitors
Maintenance notes
The standardization of the components and the circuit part, as well as the rational arrangement of the elements
used, facilitate at any time the operations of maintenance and control of the efficiency of the panel.
Automatic power factor correction equipment is designed and implemented with the aim of minimizing maintenance
interventions, however it is necessary to carry out some periodic checks every year:
check the tightening of the screws of all power connections (operation to be carried out also during
commissioning).
check the efficiency of the ventilation system. It is advisable to use a heater and blow hot air on the control
thermostats: at a temperature of about 35 ° C the fans must become operative, then at about 50 ° C, the
interruption of the auxiliary circuits that determine the block must be detected of the rephaser. Wait for the
protections to cool down for a few minutes and check for normal operation.
check the integrity of the protections (fuses, etc.).
clean the ventilation ducts of the panel. In the rephasing units with external protection class IP 40 - 54, clean or
replace the filters.
