3.4.2 RTD Connection
17
Note 1 : In 3-wire system, use always cables of the same diameter (min ) Always use
wires of the same gauge and type whether a 2-wire or 3-wire system.
1mm²
Install a jumper between terminals 2 and 3 when using a 2-wire RTD.
If the distance is longer than 10 meters, use 3-wire system
Note 2 :
