Safety information
The signal conditioner must only be configured with the DIP switch in the de-energized state.
Note
Use shielded signal lines!Only use shielded signal lines for analog input and output signals.Only then can you ensure that the accuracy and interference immunity specified for the device can be achieved, even in the presence of interference acting on the signal cable.
