to the AC and DC connectors; COM and back contact in
case of failure closed.
5. In operation with an UNB it is necessary to connect adi-
tional to SYNC GND, SYNC SIG the contacts SYNC
STAT between all of the inverters and the UNB.
6. In parallel operation the contacts SYNC GND and SYNC
SIG of each inverter has to be wired
