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

Safety instruction and CE Directives.
►
Maintain periodically
Only qualified person may perform the following works.
During the process of using the inverter, the manage person shall examine
and maintain the machine regularly. The concrete 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 and absorbed dust when
necessary. This work shall be performed from time to time.
2: Check that if the indicators of the inverter are in normal state, check if the
keys 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: Clean the inverter panels and check their security. This should be carried
out at least every 6 months.
