8.2.2 Checking the Fan
There are two ways to check that the fan is working:
• In the installer mode, set the "Fan-Test" parameter to "1" via a communication product.
or
• Plug the provided jumper into the system control board.
Setting Parameters
1. Request an installer password from the SMA Service Line (contact see page 84).
2. In the installer mode, set the "Fan-Test" parameter to "1".
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 the test, set the parameter "Fan-Test" back to "0".
☑ The test of the fans is 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 57).
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 59).
