2.5 - Wiring scheme
AVR connections
1/ Power:
- AREP: Yellow wire on X2 - red wire on
Z1 - green wire on X1 - black wire on Z2
- PMG: X2, X1 and Z2
- SHUNT: X1 and X2
2/ Field excitation:
- the field w to the terminal F+
- the field winding - to the terminal F-
3/ Battery: ensure the polarity is correct
when connecting
4/ Voltage sensing:
- mains voltage: L1 and L2
- alternator voltage:
• single-phase: V and W
• three-phase: U, V and W
5/ Current transformer(s):
- placing in parallel and measurement:
CT on U
- measurements: CTs on V and W
6/ Temperature sensor:
- PTC: see mounting above
- PT100: see mounting above
7/ USB port
8/ Digital I/O
