The maximum allowed load for the relay contacts is:
@ V= 110V / I< 0.45A
DC
@ V
60V
DC
/ I< 1A

*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.
