Installation & Operational Requirements
1.Safety-Critical Handling
Powered Removal/Insertion: Strictly prohibited unless the area is confirmed non-hazardous. This prevents electrical arcing (a ignition risk in explosive atmospheres) and avoids damage to the RIU2 or DeltaV Local Bus.
Wiring Guidelines: Refer to Emerson’s DeltaV™ Scalable Process System Zone 2 Installation Instructions (Document 12P2046) for hazardous-area wiring practices (e.g., shielded cables, proper grounding) to maintain certifications.
2.System Integration
DeltaV Compatibility: Optimized for the DeltaV™ Scalable Process System; follow the DeltaV™ M-Series Hardware Installation and Reference manual for integration steps, including Local Bus connection and network configuration.
Mounting: Intended for rack mounting in Emerson-approved control cabinets (compatible with standard 19-inch industrial racks). Ensure adequate ventilation to maintain ambient temperature within the -40°C to +70°C range.
Maintenance & Service
No User-Serviceable Parts: The RIU2 contains no components that can be serviced, adjusted, or replaced by the user. Disassembly is prohibited, as it would void safety certifications and compromise hazardous-area safety.
Calibration: Factory-calibrated for optimal communication performance; no periodic calibration is required under normal operating conditions.
Traceability: Serial number, manufacturing location, and production date are printed on the product label for warranty tracking, regulatory audits, and maintenance records.
