Fig. 14A - Negative grounding
The connection can be made in two ways:
a) Grounding of the negative DC terminal.
b) Grounding of the positive DC terminal.
WARNING: Option 'b' is only available when the inputs are configured
in parallel. YOU MUST NOT use option 'b' if the inputs are configured
independently.
Should you not wish to connect either of the two input terminals (floating
photovoltaic generator) directly to the ground, you can disconnect the connector
and store it within the dedicated housing next to the grid standard selector
switches, see Fig. 13.
NOTE: Under these conditions, both input terminals are not fully
floating, but are each connected to the ground with an impedance of
around 1.5 MOhm.
WARNING: Depending on the grid standard chosen (see section 3.4.8),
the inverter will be able to recognize any grounding which does not
respond to the applicable regulations, and an error message will appear on
the display.
