Maintenance and Cleaning
8.2.2 Checking the Fans
You can check that the fans are working in 2 ways:
• Set the "Fan‑Test" parameter to "1" in the installer mode using Sunny Data Control,
Sunny Explorer or Sunny WebBox.
or
• Plug the provided jumper into the system control board.
Setting Parameters
1. Request the installer password from the SMA Service Line (contact: see Page 86).
2. Set the "Fan‑Test" parameter to "1" in the installer mode.
3. Check the fans' air flow.
The inverter takes cooling air in from underneath and then blows it back out on the upper sides.
Listen for any unusual noise, which could indicate incorrect installation or that the fans are faulty.
4. After checking the fans, set the "Fan‑Test" parameter back to "0".
☑ The test of the fans has been completed.
Plugging the Jumper
The inverter recognizes the jumper only after the system has been restarted
(i.e. all LEDs must have gone out before a restart).
1. Open the inverter as described in section 7.2 "Opening the Inverter" (page 55).
2. Plug the provided jumper in the slot on the system control board as shown below.
3. Close the inverter as described in section 7.3 "Closing the Inverter" (page 58).
