„ Sinking/Sourcing Mode (NPN/PNP Selection)
The input terminal logic can be switched over between sinking mode (0-V common, NPN) and sourcing mode
(+24V common, PNP) by using the jumper CN5. An external power supply is also supported, providing more
freedom in signal input methods.

1. In Fig 4 the wiring of the digital inputs S1 to S7 and BB, BB1 is shown for the connection of contacts or NPN
transistors (0V common and sinking mode). This is the default setting.
For the connection of PNP transistors or for using a 24V external power supply, refer to
Table 3 .
2. A DC reactor is an option only for Inverters of 18.5 kW or less. Remove the short circuit bar when connecting a
DC reactor.

The rating of the flywheel diode must
be at least as high as the circuit volt-
age.
