Autotest Description
(CEI 0-21) 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 oth-
er. 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
once, it must be completed successfully. The autotest cannot be started during emer-
gency power mode.
