    2.6 Electrical Installation Warning The inverter must always be grounded. If the inverter is not grounded correctly, extremely dangerous conditions may arise within the inverter, which could be potentially fatal. Make sure that the grounding connection between PCB and basic housing part is applied correctly! To ensure the safe operation of the equipment, it must be installed and commissioned by qualified personnel in full compliance with the warnings laid down in these operating instructions.
