4.14 Configuring the Country Data Set
As standard, the inverter is meant for connection to a utility grid with a 208V wye connection or a
240V split-phase system, and the associated country data set UL1741/2016/120 is factory-set.
If the default country data set does not correspond with the grid configuration, the country data set
can be adapted to the connected grid configuration.
The basic procedure for changing operating parameters is explained in another section (see
Section4.13 "Changing Operating Parameters", page37).

Procedure:
• Select the parameter Set country standard and set the required country data set.
4.15 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.
Procedure:
• Set the parameter Rapid Shutdown Mode or Op.RssOpMode to On.
4.16 Changing the Operating Mode of the Multifunction
Relay
The default operating mode of the multifunction relay is Fault indication (FltInd) . If you decide to
use another operating mode and have established the correct electrical connection for this
operating mode and the associated connection variant, you will have to change the operating
mode of the multifunction relay and make other settings, if necessary.
The basic procedure for changing operating parameters is explained in another section (see
Section4.13 "Changing Operating Parameters", page37).
Procedure:
1. Call up the menu Device Parameters.
2. Select [Edit parameters].
