XDIL Drive interlock connection (input signal).
Note: This input only acts as a true Drive interlock input in control units
controlling a motor. In other applications (such as a supply or brake unit), de-
energizing the IN1 and/or IN2 terminal will stop the unit but does not
constitute a true safety function.
For more information on Drive interlock, see the appropriate hardware
manual.
XDIL OUT Drive interlock connection (output for powering XDIL input of inverter
modules).
X485 Not in use
Switch
AI1 Analog input 1 current/voltage selection
