Installation Guidelines
- Ensure adequate ventilation; the drive utilizes forced convection cooling and requires clearance for airflow.
- Mount the drive vertically on a flat, vibration-free surface.
- Use shielded cables for motor connections to comply with EMC requirements and minimize noise.
- Verify that the line voltage matches the drive input rating (380-480 VAC) before applying power.
- Always disconnect power and wait for the internal capacitors to discharge (refer to the status LED) before performing maintenance or wiring changes.
- Ensure proper grounding of the drive chassis to the main plant earth bus to prevent electrical hazards.
