Schematic in-
ternal wiring of
IOs
The V+/GND pin provides the possibility of feeding in a voltage in the range of
12.5 to 24 V (+ max. 20%) using an external power supply unit. Outputs IO 0 - 5
can then be operated using the external voltage that has been fed in. A maximum
of 1 A may be drawn per output, whereby a total of max. 3 A is permitted. The
fuse protection must take place externally.
CAUTION!
Danger from polarity reversal at the terminals due to improper connection of
external power supply units.
This may result in severe damage to the inverter.
▶
Check the polarity of the external power supply unit with a suitable measur-
ing device before connecting it.
▶
Connect the cables to the V+/GND outputs while ensuring the correct polar-
ity.
IMPORTANT!
If the total output (6W) is exceeded, the inverter switches off the entire external
power supply.
