In emergency charge mode, you must disconnect all loads, since a bridge between
AC1 and AC2 is not detected and therefore the generator current cannot be limited.
When using a bridge, the battery current sensor is not effective.
You must manually start and stop the energy source (diesel/generator), since no
generator management device is active.
If AC1 and AC2 have been bridged, the generator should first be connected and
then started (manually). Otherwise, the magnetizing current could throw the
generator fuse. (This can also happen when switching on the relay without using
a bridge).
The emergency charge mode is activated in the QCG. See section 8.2 "Starting the
Quick Configuration Guide (QCG)" (Page 57) for a detailed description on how to
access the QCG. Follow the instructions there up to point 5. The emergency charge
mode is described below.
