7.5 For Italy Only: Starting the Self-test
The self-test only applies to inverters which are commissioned in Italy.
The Italian standard requires that all inverters feeding into the electricity grid perform a self-test in
accordance with CEI 0-21. During the self-test, the inverter will consecutively check the reaction times
for overvoltage, undervoltage, maximum frequency and minimum frequency.
During the self-test, the upper and lower trip-limit values for each protective function are changed on
a linear basis for frequency monitoring and voltage monitoring. As soon as the measured value
exceeds the permitted trip-limit value, the inverter disconnects from the electricity grid. Thus, the
inverter determines the reaction time up to disconnection and performs the self-test.
After the self-test has been completed, the inverter automatically switches back to feed-in operation,
resets the original calibration values and connects to the electricity grid. The test takes approx.
3 minutes.
Requirements:
Configured country data set: CEI0-21 Int / CEI 0-21 Intern or amended country data set
trimmed / Special setting based on CEI0-21 Int / CEI 0-21 Intern.
A report for entering the test results in compliance with CEI 0-21 must be on hand.
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 the display once within
ten seconds.
A message informing you that the self-test has started is shown in the display:
Avvio Autotest.
✖No message Avvio Autotest shown in the display
You have exceeded the ten-second time limit so the self-test cannot start.
Restart the self-test
Tap the display within 20 seconds and enter the test results in 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.
Example: Display messages for overvoltage test
Name of the test: Autotest (59.S1) 240.00V
Disconnection value: Valore di soglia con 230,00 V
•Normative value: Va. taratura 253.00V
Disconnection time: Tempo intervento 0.02s
Current mains voltage: Tensione di rete Val.eff.: 229.80V
