Self test in accordance with ENEL directive for initial start-up
(applies to Italy only)
The Italian standard prescribes that an inverter can only operate on the public grid after
the disconnection times for overvoltage, undervoltage, minimum frequency and maximum
frequency have been checked.
If you have configured the Enel-GUIDA country data set, start the self-test as described in
section 7.3”Self-Test in accordance with ENEL Directive, Ed. 1.1 (Applies to Italy only)”
(page54). The test takes approx. 3 minutes.
