Connecting RTD and mA inputs

Connect the wires from the transducers to the correct device according to the connection
diagram. Each terminal for RTDs and mA inputs is dimensioned for one 14 or 16 Gauge
wire.
See the specific card variant from the application manual.
Connect the RTD cable shield to the protective ground. To suppress RF
interference, connect the RTD cable shield straight to the lead that
connects to the protective ground screw and not to the protective screw
itself. The connection should not be longer than 5 inches from the
protective ground screw.
