8.2.2 Checking the Fans
There are two ways to check that the fans are working:
• 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 80).
2. Set the "Fan-Test" parameter to "1" in the installer mode.
3. Check the air flow of the fans.
The inverter draws air in from underneath and then blows it back out on either side at the top.
Listen for any unusual noise, which could indicate incorrect installation or a fault in the fans.
4. After checking the fans, set the "Fan-Test" parameter back to "0".
☑ The fan test is now complete.
Plugging the Jumper
The inverter recognizes the jumper only after a system restart (i.e. all LEDs must have gone out prior
to restart).
1. Open the inverter as described in Section 7.2 "Opening the Inverter" (page 48).
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 51).
4. Check the air flow of the fans.
The inverter draws air in from underneath and then blows it back out on either side at the top.
Listen for any unusual noise, which could indicate incorrect installation or a fault in the fans.
5. After checking the fans, remove the jumper. Open and close the inverter as described in
Section 7 "Opening and Closing" (page 48).
☑ The fan test is now complete.
