Disconnection from the ex-
ternal grid due to insufficient
battery voltage or overvolt-
age at line conductor L1: The
master disconnects from the ex-
ternal energy source because
the voltage at connection AC2
is too high or the battery volt-
age too low.
1 Disconnection from the ex-
ternal grid due to insufficient
battery voltage or overvolt-
age at line conductor L2:
Slave 1 disconnects from the ex-
ternal energy source because
the voltage at connection AC2
is too high or the battery volt-
age too low.
1 Disconnection from the ex-

is too high or the battery volt-
age too low.
10 Troubleshooting
Corrective measures
• Ensure that the conductor cross-
section of the AC cables is correctly
sized.
• Contact the Service, if required (see
Section 16 "Contact", page 161).
