Checking the connections on the battery converter

•
Check whether the system reports a current flow (realistic currents) on all three phases.
There is a fault if the value for the current (I network) oscillates between +0.01 and ­0.01 on all three phases.
Check the cable connection to the current sensor.
Note: The system may need to be charged with a large consumer on all three phases.

The store should automatically go into backup mode.
•
Interrupt the connection to the consumers for a few seconds.
•
Check whether the replacement power network was developed and the consumers are in operation.
Note: Remember that some consumers change operating mode only after a few minutes. Test the replacement
power network over a sufficiently long time.
•
Check in the web interface whether error messages are displayed.
•
Fault remedy: Possibly inrush current too great. Reduce the consumers and carry out the check again.
