3.4 Integrated DC Switch
Depending on the option ordered, the Sunny Central CP-US inverter may be fitted with an integrated DC Switch. The
DC Switch enables you to disconnect the inverter from the PV array in the event an emergency and for service- and
maintenance work. Despite disconnecting the integrated DC Switch, voltages are still present on the DC fuses and the
inverter busbars. Touching the DC fuses or the busbars will result in death or very serious injuries from electric shock.
