Installation Guidelines

• Environmental Protection: The IP55 rating ensures the drive can handle dust and moisture; however, ensure the unit is mounted in an area with adequate airflow to prevent heat buildup within the enclosure.
• Clearance: Maintain proper spacing above and below the unit to allow for efficient cooling and to comply with thermal dissipation requirements.
• Grounding: A high-integrity earth connection is mandatory for safe operation and to ensure internal filtering remains effective.
• Commissioning: As this product is in the Phase-Out stage, ensure your current control system software and configuration tools are compatible with the Altivar 31 series parameters before beginning installation.
