ation from inverter to inverter.
WSD terminal
Push-in terminal for the WSD installa-
tion. See chapter

down) " on page 22 .
USB Power supply max. 1 A at 5 V. Software
updates and data recording via USB is
not possible.
IOs terminal

IOs On the V+/GND pin, it is possible to feed in a voltage of around 12.5 - 24 V (+ max. 20%)
with an external power supply. The outputs IO 0 - 5 can then be operated with the
external voltage. A maximum of 1 A can be drawn per output, with a maximum of 3 A
allowed in total. The fuse protection must be located externally.
CAUTION!
Risk of polarity reversal at the terminals due to improper connection of external
power supplies.
This may result in severe damage to the inverter.
▶
Check the polarity of the external power supply with a suitable measuring device
before connecting it.
▶
Connect the cables to the V+/GND outputs with the correct polarity.
IMPORTANT!
If the total output (6 W) is exceeded, the inverter switches off the entire external power
supply.
