5. Installation and Maintenance

Installation

Insert it through the dedicated slot on the rack backplane to ensure connection with the backplane and power bus of the 3500 system. It is recommended that wiring and commissioning be performed by professional engineers.

Maintenance

The module is designed with a sealed structure (IP65), which has strong resistance to environmental dust and moisture and usually does not require frequent cleaning. It is recommended to regularly check the connection status of sensor cables and the power supply voltage of the module to prevent inaccurate measurement or signal loss caused by external environmental impacts.
