Maintenance operations are required to be carried out by personnel familiar with and specifically trained in the
operations of this inverter. ABB recommends personnel having appropriate NABCEP certification and/or other
professional licensing and/or having received training through ABB or other authorized organizations.
DO NOT allow the equipment to be used if problems of any kind are found
WARNING! Maintenance operations must be carried out with the equipment disconnected from the
grid, unless otherwise indicated.
After shutdown, wait at least 10 minutes before removing guards or covers in order to allow devices
inside the unit to cool and allow any electrostatic charges and parasitic voltages to dissipate.
For cleaning, DO NOT use rags made of filamentary material or corrosive products that may damage parts
of the equipment or materials which may generate electrostatic charges. Avoid temporary repairs. All repairs
should be carried out using only genuine spare parts. The maintenance technician is under an obligation to
promptly report any anomalies.
Always use the personal protective equipment provided by the employer and comply with the safety conditions
in section 1 of this manual. ABB accepts no liability if the periodic checks and maintenance cycles indicated in
this manual and in the attached documentation are not complied with correctly, or if maintenance is entrusted
to unqualified staff.

outine maintenance
Routine maintenance operations can be carried out by the user or by the installer.
Clean the equipment at least annually; in particular, the lower grill on the wiring box through
which the air for cooling the heatsink passes and the heatsink itself. If possible, use an
extractor or suitable pipe cleaners.
Annually or in the event of malfunction, check that the environmental conditions have not
changed drastically (exposure to weather conditions); also check that the inverter chassis has
not been isolated by foreign bodies such that airflow may be affected.
Annually or in the event of malfunction, check the tightness of the cable opening plugs, the fit -
ting of the connectors and front covers. Loose fittings can allow water seepage into the cabinet
possibly leading to short circuit conditions due to high humidity.
