DANGER!
The inverter must be grounded to a protective earth for safety
purposes (PE).
The earth or ground connection must comply with the local
regulations.For grounding, use cables with cross sections as
indicated in Table 3.3.
Make the ground connection to a grounding bar or to the ge-
neral grounding point (resistance 10 < ohms). Do not share
the ground wiring with other equipment that operate with high
currents (for instance: high voltage motors, welding machines,
etc). If several inverters are used together, refer to Figure 3.5.
