SMA SB 1300TL Installation - Manual (Page 6)

2 Self-Test in Accordance with CEI 0-21 for Plants ≤ 6 kW SMA Solar Technology AG
6 CEI0-21_B-IA-it-en-de-20
2. Tap on the display within 20 seconds and enter the test results into the test report as they
appear.
☑ The self-test starts.
☑ The inverter displays the results of the individual tests for overvoltage, undervoltage,
maximum frequency and minimum frequency. The results are displayed three times in
succession for ten seconds each.
2.2 Abortion of the Self-Test
If, during the self-test, an unexpected disconnection requirement occurs, the self-test is aborted. The
same applies if the DC voltage is so low that feed-in cannot be continued.
• A message informing you that the self-test has been aborted is shown in the display for ten
seconds: Autotest interroto.
• Restart the self-test (see Section 2.3).
2.3 Restarting the Self-Test
1. Disconnect the miniature circuit-breaker and secure against accidental or unintentional
re-connection.
2. If the multi-function relay is used, switch off the load supply voltage.
3. Remove the ESS from the inverter for five minutes and then plug it in again.
4. Restart the inverter
☑ The inverter is once again in the start-up phase and you can start the self-test (see Section
2.1).
