17.4. Connection process of the synchronization input for three-
phase systems (hardware type B)
To perform the synchronization input connection, follow the process below on each inverter:
1.
Loosen the corresponding packing gland (see Section
“2.7. Description of wiring inlets”
and pass the cable through it.
2.
Connect the inverter wiring from the previous phase to the
J75 PHASE SYNC
terminal in positions
RX-
and
RX+
, respecting the polarities. Ingeteam recommends using a tubular terminal in accordance with
DIN 46 228/1
.
3.
Connect the inverter wiring from the next phase to the
J75 PHASE SYNC
terminal in positions
TX-
and
TX+
,
respecting the polarities. Ingeteam recommends using a tubular terminal in accordance with
DIN 46 228/1
.
