Installation & Maintenance Guide

Installation Requirements

• Mount the drive unit vertically inside an IP54-rated or well-ventilated enclosure to ensure proper vertical airflow across heatsinks.
• Maintain recommended clearance space above, below, and on the sides of the drive chassis for unhindered heat convection.
• Use shielded control lines and verify proper earth grounding (PE terminal connection) to ensure optimal EMI filter performance.
• Verify grid supply voltage matches the drive model specification before connecting input power.

Maintenance Tips

• Clean dust, lint, and ambient particulate accumulation from cooling vents using clean, dry compressed air every 3 to 6 months.
• Regularly check power terminal block screws for tightness to prevent high-resistance heating caused by machine vibration.
• Ensure control panel interior ambient temperatures stay below 50°C during continuous full-load operations.

Safety Instructions

• Always disconnect incoming main AC power and wait at least 10 minutes for internal DC bus capacitors to fully discharge before opening covers.
• Never apply AC input main power directly to output motor terminals U, V, and W.
• Wiring, parameter configuration, and routine servicing must be performed by certified electrical engineers or automation technicians.
