Wiring, shield connections

To prevent noise being induced onto any of the analog inputs or outputs, it is advisable to use twisted pair cable shielded with an overall outer shield.
The shield connections should be terminated at one of the zero volt terminals on the Option module, and to the zero volt connection of the signal
source. The termination of the shield should be kept as short as possible to prevent and noise being induced in this area.
