DANGER!

It is mandatory to connect the inverter to a protection ground (PE). The grounding connection must
follow the local regulations. Use at least conductors with the wire gauge indicated in the 

Table 6.4 

on page 6-10

. Connect the inverter to a specific grounding rod or to the general ground system 

(resistance ≤ 10 Ohms).
