Maintenance task
Check the heater and humidistat. Set the threshold of the humidistat below the ambient hu-
midity and check that the heater starts working. After testing, set the threshold to 80%.
Check the high voltage electric display light and that the second locked circuit is normal.
Check that the thermal relay setting value is correct.
Do a close test for the vacuum contactor or breaker, and check that the operation and feed-
back status is correct.
Check that the fuse and breaker is normal and there are no burn marks.
Change the battery every 3 years for reliable operation.
If the drive is stored for over 3 months and is not turned on during that time, charge the UPS
battery for 8 hours.
Charge spare storage batteries every 3 months.
The brightness of the HMI decays over time. The lifetime depends on the use conditions.
Change every 4 years for reliable operation.
Change every 4 years.
Change every 5 years.
Change every 10 years.
If a stored power cell has not been energized in the last 1 year, the electrolytic capacitors
must be reformed.
If the drive is stored for more than 2 years, high voltage cannot be applied directly to the
drive. Raise the input voltage gradually to wait until the capacitors are charged properly.
