Note
In case of using the RS-485 interface (X3) it is necessary to clamp the shield of the communication cable
to the DIN rail. This shield clamping should be done close to the system.
Note
The assignment of X3 is independent whether a termination is existing or not
(termination = resistance that is connected through parameter in the firmware).
