Please make regular inspections to the places which are hard to be inspected during running.
Regular inspection items:
1) Inspect the air channel and clean it regularly
2) Inspect whether the screw is loose
3) Inspect whether the frequency converter suffers from corrosion
4) Inspect whether the terminal block has the arc traces
5) Insulation test for major loop
Remind: when using the megameter (use DC 500V megameter please) to measure the insulation resistance, the major loop line needs to be disconnected with the frequency converter. Do not use the insulation resistance meter to measure the insulation of the control loop. No need to conduct the high voltage test (it is already completed in delivery).
