8.7 Activating of the Rapid Shutdown DC discharge
function
The DC discharge function should be activated if an additional DC switch-disconnector between the
inverter and the PV array is available. The additional DC switch-disconnector disconnects the PV
array in the case of a rapid shutdown.
The basic procedure for changing operating parameters is explained in another section (see
Section 8.2 "Changing Operating Parameters", page 39).
Procedure:
• Set the parameter Rapid Shutdown Mode or Op.RssOpMode to On.
