NOTE Connecting the
DC wiring with the wrong
polarity may cause dama-
ge to the inverter.
Check both the polarity
and the open circuit volta-
ge.
The DC Voltage must not exceed
600 V, regardless of temperature.

Important
- Set the jumper from the ‘SMON’ position to the ‘SMOFF’ position for
correct measurement results
- Check the polarity and voltage of the solar module strings: the DC-
voltage must not exceed 600 V, the difference between the individual
solar module strings should be less than 10 V.
