Connecting Additional Grounding
If additional grounding or equipotential bonding is required locally, you can connect additional
grounding to the inverter. This prevents touch current if the grounding conductor at the connecting
terminal plate for the AC cable fails. The required clamping bracket, the screw and the conical
spring washer are part of the scope of delivery of the inverter.
