Requirements:

☐ Configured country data set: CEI 0-21 Int or CEI 0-21 internal or amended country data set

trimmed or Special setting based on one of the country data sets mentioned above.

☐ A report for entering the test results according to CEI 0-21 must be available.
☐ The inverter must be in operation and in the start-up phase.

Procedure:

1. As soon as the configured country data set appears in the display, tap once on the display

within ten seconds.

☑ A message informing you that the self-test has started is shown in the display:

Avvio Autotest.

✖ The message Avvio Autotest is not shown in the display?

The ten seconds have elapsed so the self-test cannot start.

• Restart the self-test (see Section 7.5.2, page 36).

2. Tap on the display within 20 seconds and enter the subsequent test results into the test report.

☑ 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.
Useful hint: If you want to have the next result displayed without waiting ten seconds, tap twice
on the enclosure lid.

✖ The information Autotest interroto is shown in the display?

The self-test was cancelled due to an unexpected disconnection condition or the DC voltage is
too low to continue grid feed-in.

Restart the self-test (see Section 7.5.2, page 36).

Example: Display messages for overvoltage test

- Name of the test: Autotest (59.S1) 240.00V
- Disconnection value: Valore di soglia con 230.00V
- Normative value: Va. taratura 253.00V
- Disconnection time: Tempo die intervento 0.02 s
- Current grid voltage: Tensione di rete Val.eff.: 229.80V

7.5.2

Restarting the Self-Test

1. Disconnect the circuit breaker and secure it against reconnection.
2. If the multifunction relay is used, disconnect the supply voltage to the load.
3. If an external DC load-break switch is used, switch it off for five minutes and then switch it on

again.
