NOTICE
Damage at the switchgear
There is no internal inrush current limiting at terminals BT+ and BT-.
Therefore, energy storages should only be connected if they are di-
scharged. Instructions for switchgear use at these terminals and for the
recommended switching sequence on request at KEB. Non-observan-
ce may lead to damage of the switchgear.
