Unused analog input pins should be connected to a ground pin. This is required even if the unused channels are turned off. If unused analog inputs remain floating, they may impair the performance of the active channels.

The signal level of the analog input pins on the I/O connector must be in the range -48 V to +48 V (referenced to ground)!
