IOs terminal
Internal schem- On the V+/GND pin, it is possible to feed in a voltage of around 12.5 - 24 V (+ max. 20%)
atic connection with an external power supply. The outputs IO 0 - 5 can then be operated with the
diagram of the external voltage. A maximum of 1 A can be drawn per output, with a maximum of 3 A
IOs allowed in total. The fuse protection must be located externally.
Risk of polarity reversal at the terminals due to improper connection of external
power supplies.
This may result in severe damage to the inverter.
