Installing the SMA Plug-in Grounding

4 Installing the SMA Plug-in Grounding
If a ground fault occurs in the PV plant, the fuse in the SMA Plug-in Grounding interrupts the residual
current.
The positive or negative grounding of the inverter is coded in the SMA Plug-in Grounding. You must
only start up the inverter, if the SMA Plug-in Grounding is installed according to the grounding of your
PV plant.
Connection area
The connection area in the SMA Plug-in Grounding can
be found at the underside of the inverter.
Procedure
1. Disconnect the inverter on the AC and DC sides as described in the inverter's installation guide.
2. Check whether the SMA Plug-in Grounding has been tightened properly:
Hold the connecting part of the SMA Plug-in Grounding tightly and tighten the cap by hand.
☑ The SMA Plug-in Grounding has been tightened
properly, if the symbols on the connecting part
and the cap together form a lock.
3. Remove the protective cap from the plug-in position
on the inverter.
