6.1.2 Parameter "Prescribed grounding type" or
"Md.GndModReq"
Via the parameter "Prescribed grounding type" or "Md.GndModReq" you will be able to specify the
required grounding type. Default configuration for the parameter is "Learning" or "GndModLrn".
There are two ways to specify this parameter:
• Automatically: When in learning mode, the inverter automatically saves the grounding type
of the plugged in SMA Plug-in Grounding after 10 hours of operation.
• Manually: You can change the grounding type you want to use via the communication tool
(Bluetooth/RS485), after you have started up the inverter. It is also possible to manually
configure the parameter without the SMA Plug-in Grounding.
There are four configuration options:
