3.3.2 Electrical Connector X1 for UNV48-5.0F (HAN K 6/6)

X1/Pin Designation

1 DC input, Plus

2 ---

3 ---

4 AC output, phase L1

5 DC input, Minus

PE PE

6 AC output, neutral conductor

11 Collective failure COM*

12 SYNC-GND (synchronous bus ground)

13 Collective failure OK (normally open=NO)

14 Collective failure error (normally closed=NC)

15 SYNC-SIG** (synchronous bus 50Hz-signal)

16 SYNC-STAT*** (synchronous bus state lines)

*Potential free relay contact with safe electrical separation to the AC and DC side; in case of failure COM and NC

are closed.

**In parallel operation the contacts SYNC – GND and SYNC – SIG of each inverter have to be wired.

*** In operation with an UNB it is necessary to interconnect the synchronization bus (contacts SYNC – GND,

SYNC – SIG and SYNC – STAT) between the inverter(s) and the UNB.
