9.2 Routine Maintenance
Inverters do not require any maintenance or correction in most cases, but if
the inverter often loses power due to overheating, this can be attributed to the
following reason:
• Heat sink behind the inverter is covered with dirt.
If necessary, clean the cooling heat sink with a soft dry cloth or brush. Only
trained and authorized professionals familiar with safety requirements can
perform maintenance and maintenance work.
Safety checks should be conducted at least every 12 months, Contact the
manufacturer to arrange for appropriate training, expertise, and practical ex-
perience in performing these tests.
(Note that this action is not covered by warranty).
These data should be recorded in the device log. If the equipment is not run-
ning properly or any test fails, the equipment must be repaired for details of
safety inspections, refer to section 2 of this manual for safety instructions and
Europe commission instructions.
