I DC Load-Break Switch
The inverter is equipped with a DC load-break switch. If the DC load-
break switch is set to the position I, it establishes a conductive connection
between the PV array and the inverter. Setting the DC load-break switch
to the O position interrupts the DC electric circuit and completely discon-
nects the PV array from the inverter. Disconnection takes place at all
poles.
