Installation Guidelines

• Mount the variable frequency drive vertically onto a clean, solid, and grounded mounting plate inside the control cabinet.
• Ensure adequate clearance spaces above and below the drive housing to maintain unimpeded cooling airflow and prevent thermal overload.
• Connect the 240V power supply lines, motor cables, and control wiring using shielded cables in accordance with EMC guidelines.
• Verify parameter settings and graphic terminal connections before energizing the drive system.
