Installation Guidelines

• Securely snap mount the compact main unit onto standard industrial DIN rail assemblies housed inside an appropriate protective enclosure.
• Wire an external 24 VDC power source paying strict attention to terminal polarities to meet the rated hardware voltage demands.
• Provide sufficient ambient layout spaces conforming to the device structural constraints (135 mm height x 82 mm width x 74 mm depth) to guarantee unhindered cooling airflow.
• Separate all serial RS485 communication line routes and digital sensor input paths away from primary motor or switching supply lines to suppress inductive noise coupling.
