• Ground the shield drain wire at one end only. The typical location is the same point as
the sensor ground reference.
– For grounded thermocouples or millivolt sensors, this is at the sensor end.
– For insulated/ungrounded thermocouples, this is at the module end. Contact your
sensor manufacturer for additional details.
• If it is necessary to connect the shield drain at the module end, connect it to earth
ground using a panel or DIN rail mounting screw.
• Routing the field wiring in a grounded conduit can further reduce electrical noise.
