Field Installation Guidelines

Ensure system auxiliary power is completely de-energized and discharge static buildup before inserting or handling the circuit board. Observe anti-static precautions (ESD wrist strap) and mount the board firmly onto the chassis backplane guide rails, ensuring all retention latch screws are tightened. All field-side signal connections for digital and analog I/O must be routed using shielded cables grounded at a single earth point to maintain noise immunity in industrial environments.
