Cleaning the Fans
If the inverter reduces its power due to overtemperature or even switches off, it is possible that the fan on the bottom of the inverter is no longer working properly due to contamination. Clean the fan as described in the following.
- Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).
- Press the two locking tabs together to release the fan drawer and carefully pull the enclosure with the fan out downward.
- Disconnect the fan connector in the unlocked state.
- Clean the fan assembly with a soft brush or a vacuum cleaner.
- Reinstall the serviced fan assembly in the inverter.
- Recommission the inverter ( > Commissioning the Inverter).
