Installation Guidelines

Ensure the control system is powered down before installing or removing the terminal board to prevent electrical damage.
Handle the module using proper ESD (Electrostatic Discharge) precautions to protect sensitive internal components.
Verify that all field wiring is properly shielded and routed away from high-voltage or high-EMI sources to maintain signal integrity.
Ensure proper grounding of the terminal board chassis to the system common as specified in the Honeywell TDC installation manual.
Confirm that the terminal board is securely seated in the designated rack slot to ensure reliable contact with the backplane.
