Power supply
Connectors X21 and X22
The device is supplied via connector X21 (PWR IN). You can connect two supply lines to the connector:
- Supply line 1: 1L (U1L) and the reference potential 1M
- Supply line 2: 2L (U2L) and the reference potential 2M
Both supply lines are electrically isolated.
Each pin of connector X21 (PWR IN) is connected to the same pin of socket X22 (PWR OUT) and is
used to forward the supply to the next device.
For identifying the connector X21 on the board, see position (20), and connector X22, see position (8) in
section Device overview TigoMaster 2TH- [page 6].
