7.2 Routine Maintenance
Inverters do not need 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:
· The cooling fins on the rear of the inverter are covered by dirt.
• Clean the cooling fins with a soft dry cloth or brush if necessary.
• Only trained and authorized professional personnel who are familiar with
the requirements of safety are allowed to perform servicing and
maintenance work.
• Before cleaning, please wait for a few minutes to make sure the machine
is cooled down and make sure the machine is shut off in case of electric
shock.
Safety checks
Safety checks should be performed at least every 12 months by
manufacturer's qualified person who has adequate training, knowledge, and
practical experience to perform these tests. The data should be recorded in
an equipment log. If the device is not functioning properly or fails any of test,
the device has to be repaired. For safety check details, refer to section 2
Safety instruction and CE Directives on this manual.
Maintain periodically
During the process of using the inverter, the manage person shall examine
and maintain the machine regularly. The specific operations are as follows.
1) Check that if the cooling fins on the rear of the inverter are covered by dirt,
and the machine should be cleaned when necessary. This work shall be
checked time to time.
2) Check that if the indicators of the inverter are in normal state, check if the
display of the inverter is normal. This check should be performed at least
every 6 months.
3) Check that if the input and output wires are damaged or aged. This check
should be performed at least every 6 months.
4) Check whether the ground terminal and ground cable are securely
connected and all terminals and ports are properly sealed every 12 months.
5) You should get the inverter panels cleaned and their security checked at
least every 6 months.
