7.3 Jumper Assignments for Grounding Systems
At the factory, the inverter is configured for connection to the power distribution grid via a neutral
conductor. By setting the jumper, the inverter can be configured for various grounding systems. This
means it is possible to connect the inverter to grounding systems without a neutral conductor
(e.g. to a 240 Delta or 208 Delta).
