inverter. The connection of the cable will causes the interruption of the operation of the inverter, i.e. it
stops the IGBT switching, interrupts the injection of current into the grid and open the AC contactor.
WARNING – B The REMOTE OFF function doesn’t cause the disconnection of power sources from
the inverter!
