Installation Guidelines
Ensure the module is installed within an appropriate S900 I/O mounting base.
Always power down the segment or follow site-specific hot-swap safety protocols before inserting or removing the module from the rack.
Maintain proper grounding practices to preserve the integrity of the intrinsic safety barriers.
Ensure that wiring for intrinsically safe circuits is segregated from non-intrinsically safe wiring to prevent cross-contamination of signals.
Verify that the ambient operating temperature does not exceed the specified 60 degC limit to prevent premature component degradation.
