• Ground the shield drain wire at only one end. 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 by using a panel or DIN-rail mounting screw.
• Routing the field wiring in a grounded conduit can further reduce electrical noise.
Label the Terminals
A removable, write-on label is provided with the module. Remove the label from the door,
mark your unique identification of each terminal with permanent ink, and slide the label back
into the door. Your markings (ID tag) will be visible when the module door is closed.
Remove the Finger-safe Terminal Block
To remove the terminal block, loosen the upper and lower retaining screws. The terminal
block will back away from the module as you remove the screws. When replacing the terminal
block, torque the retaining screws to 0.46 N•m (4.1 lb•in).
