5. Installation and Maintenance Guidelines
5.1 Installation Requirements
Rack Compatibility: The module must be installed in a standard Bently Nevada 3500 system rack, ensuring a secure backplane connection with other monitoring modules such as 3500/60 and 3500/62.
Power Wiring: Connect the input side to an industrial power supply compliant with IEC 60038 standards, and use cables that meet IEC 60204-1 standards for wiring.
Grounding Protection: Reliable grounding is mandatory to prevent electromagnetic interference from affecting measurement accuracy.
5.2 Maintenance Tips
Regular Indicator Inspection: The power supply module is equipped with status indicator lights (LED). Color changes (green/red) directly reflect whether the module is functioning normally.
Heat Dissipation System Cleaning: In high-temperature environments such as steel plants, remove dust from heat sinks regularly to avoid automatic protection tripping caused by overheating.
Spare Parts Management: Keep at least one spare module of the same model to enable quick replacement in case of failure, avoiding the shutdown of the entire monitoring line.
