Autotest
(CEI 0-21) Description
The 'Autotest' can be used to check the protective function required by the Italian stand-
ard for monitoring the voltage and frequency limits as well as the trip limits of the inverter
during commissioning. During normal operation, the inverter constantly checks the cur-
rent voltage and frequency actual value of the grid.
After the start of the autotest, various individual tests run automatically one after the
other. Depending on grid conditions, the duration of the test is approx. 15 minutes.
IMPORTANT!
The inverter may only be commissioned in Italy after a successful autotest (CEI 0-21). If
the autotest is not passed, no feed-in operation may take place. If the autotest is started
