3.3 Electrical Connectors

3.3.1 Electrical Connector X1 for UNV-F 2.5 – 3.3kVA, UNV60-5.0F and UNV110-5.0F

X1 (HAN-K4/8) socket outlet (DC input voltage / AC output voltage and signalling):

X1/Pin Designation

1 DC input, plus pole

2 AC output, neutral conductor

3 DC input, minus pole

4 AC output, phase L1

5 ---

6 SYNC-GND (synchronous bus ground)

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

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

9 ---

10 Collective failure COM***

11 Collective failure OK (normally open=NO)

12 Collective failure error (normally closed=NC)

The maximum allowed load for the relay contacts is:

 @ V= 110V / I< 0.45A

 @ V 60V

DC / I< 1ADC

*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.

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

NC are closed.
