Configuring the terminal block
5
Before you configure the inputs and outputs of the inverter, you should have completed the
basic commissioning, see Chapter Commissioning (Page 55) .
The assignment of the inputs and outputs in the factory setting and after the basic
commissioning are listed in Chapter Wiring examples for the factory settings (Page 64).
5.1
Digital inputs
The digital inputs are pre-assigned specific functions in the factory. Depending on the
Control Unit version, up to 8 digital inputs are available, of which, digital inputs DI 11 and
DI 12 (terminals 3 and 10) can also be used as analog inputs.
