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

CAUTION!
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.
