Units connected to transformers with the low-voltage side in delta connection or star
without accessible neutral
To connect to transformers with the low-voltage winding in delta or to transformers without the neutral accessible,
it is necessary to change the position of a wire in the -CCU.
Connect the cable going to -J10.1 (labeled as N on the card) from the -CCU in J10.2.

16.6. Connecting the Medium Voltage switchgear emergency trip

These units have a normally open voltage-free contact for the emergency trip of the Medium Voltage switchgear or
the equivalent protection upstream of the inverter.
The wiring must be connected between positions B and C of terminal -X38.2. Below is an example diagram,
although other alternatives that produce the same result are possible (tripping the Medium Voltage switchgear).
In the event of several inverters connected to the same transformer, the wiring must be done in parallel through a
single power supply.
