Due to the changed protective circuit on the inputs and outputs, the restrictions
concerning the input signal voltage described in the existing documentation no
longer apply.
When the channels of connector X6 are to be used as inputs, the respective
outputs (high-end switches) must be switched off.
The dimensions for the assembly holes are the same for the replacement
device and the existing device.
