6.3 Self-Test in accordance with DK 5940, Ed. 2.2
(Applies to Italy Only)
6.3.1 Starting the Self-Test
You can start the self-test by tapping on the enclosure lid. Prerequisite here is that the country
configuration of the inverter has been set to Italy (DK5940E2.2) or a reconfiguration based on the
DK5940E2.2 country data set has been carried out. In addition, an undisturbed feed-in operation
must be possible.
Proceed as follows for checking the disconnection times:
1. Commission the inverter as described in section 6 ”Commissioning” (page 53).
☑ The inverter is now in the initialization phase.
– Firstly, the firmware version of the internal processors appears in the text lines.
– After 5 seconds or after tapping the enclosure lid, the serial number or the description of
the inverter appears. The description of the inverter can be changed with a
communication device.
– After a further 5 seconds, or when you tap
again, the configured standard is displayed.
2. In order to start the self-test, tap on the enclosure
cover within 10 seconds.
☑ The message shown on the right appears in the
display.
3. Now activate the self-test within 20 seconds by tapping on the enclosure lid again.
☑ Once you have started the test sequence, the inverter checks the disconnection times for
overvoltage, undervoltage, maximum frequency and minimum frequency one after the other.
During the tests, the inverter shows the values in the display which are described in section
6.3.2 ”Test Sequence” (page 56).
Display Language during the Self-Test
Independent of the configured language, the display messages for the self-test will always
be displayed in Italian.
