ABB ACS380 - NPN Configuration for Digital Inputs; Connection Examples of Two-Wire and Three-Wire Sensors

NPN configuration for digital inputs
Internal and external +24 V power supply connections for NPN (sink) configuration are
shown in the figures below.
WARNING!
If you connect DIO1 or DIO2 as shown in the figures below, make sure that they
are configured as inputs. If they are configured as outputs, it can cause damage
to the equipment.
