Chapter 3 Installation and Wiring
Noise Prevention Guidelines
• To limit the pickup of electrical noise, keep thermocouple and millivolt
signal wires as far as possible from power and load lines.
• If noise persists for a device, try grounding the opposite end of the cable
shield. (You can ground only one end at a time.)
Terminal Door Label
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.
Removing and Replacing the Terminal Block
When wiring the module, you do not have to remove the terminal block. If you
remove the terminal block, use the write-on label located on the side of the
terminal block to identify the module location and type.
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.
Be careful not to damage the CJC sensors. When replacing the terminal block,
torque the retaining screws to 0.46 N•m (4.1 lb•in).
