Installation Guidelines

• Ventilation: Ensure vertical mounting to allow proper airflow. Keep at least 100 mm of clearance above and below the unit for cooling.
• Environment: Install in a clean, dry, and dust-free environment with an ambient temperature not exceeding 40 degC.
• Wiring: Connect the 3-phase supply to the appropriate input terminals and the motor to the output terminals. Ensure all wiring is shielded to minimize electromagnetic interference (EMI).
• Grounding: Proper PE (Protective Earth) connection is mandatory to ensure safety and compliance with electrical standards.
• Mounting: Designed for panel mounting; secure the unit firmly using the integrated mounting points.
