DANGER!
Fatal electric shock hazard!
In daylight the PV generator supplies the inverter with a danger-
ously high DC voltage.
●
The PV generator voltages are very high. NEVER plug or
unplug the DC connectors when the inverter is turned on, oth-
erwise dangerous electric arcs could develop.
Connection of PV input cable
1. Cut the cable isolation for a length of 8 … 10 mm. Crimp the cable into the
metallic terminals provided, observing the correct polarity (red cable goes
in the terminal of the female positive pole connector; black cable goes in
the terminal of the male negative pole connector).
