Care, maintenance and disposal
General
The inverter is designed in such a way that no additional maintenance work builds up.
Nevertheless, a few points must be considered during operation to ensure that the invert-
er works perfectly.
Maintenance
Maintenance and servicing may only be carried out by Fronius-trained service techni-
cians.
Cleaning
Clean the inverter as required with a damp cloth.
Do not use cleaning agents, abrasives solvents or similar to clean the inverter.
Safety
The DC disconnector is used only to switch off power to the power stage set. When the
DC disconnector is turned off, the connection area is still energized.
Danger from grid voltage and DC voltage from solar modules.
An electric shock can be fatal.

Operation in
NOTE!
dusty environ-
ments
If the inverter is operated in dusty environments, dirt may build up on the heat sink
and fan.
This may result in a loss of power due to insufficient cooling of the inverter.

WARNING!
The connection area must only be opened by an authorised electrician.
The separate power stage set area must only be opened by Fronius-trained service
technicians.
Prior to any connection work, disconnect the inverter on the AC side and the DC
side.
WARNING!
Allow the capacitors of the inverter to discharge (2 minutes).
Make sure that the ambient air can always flow through the inverter's ventilation
slots unimpeded.
Remove any build-ups of dirt from the heat sink and the fan.
