Connections
Connection to meter or CU adapter
10-pin connector at rear of CU
External 5 V power supply (only for E650 meters)
2-pin connector; recommended for a reliable modem
operation for M circuits and the supply voltage
phase – neutral is 58 V nominal and 64 V nominal
where there is only one phase present.
Landis+Gyr should be consulted if supply voltage is
between 100 V nominal and 115 V nominal where Example CU-P42
there are only one or two phases present.
The statements above apply to E650 series 3
meters (firmware version B31 or higher).
Information on previous versions can be found in the
user manual.
