Physical Installation Guidelines

• Enclosure Clearance: Maintain adequate vertical and horizontal spacing around the module housing to allow for proper convective airflow and thermal dissipation.
• DIN-Rail Mounting: Secure the unit firmly onto a standard 35 mm industrial DIN rail, verifying that the mechanical locking mechanism engages completely.
• Wiring Termination: Connect incoming power and serial communication lines securely into the terminal blocks, ensuring proper conductor strip length to prevent exposed copper.
• Grounding Compliance: Fasten the base assembly directly to a grounded metal panel or mounting plate to mitigate electromagnetic interference and ensure noise immunity.
