Installation & Maintenance Guide

Installation Requirements

• Mount vertically inside an IP54-rated or ventilated control box to maintain proper cooling airflow.
• Ensure clear vertical space above and below the drive unit for adequate heat dissipation.
• Use shielded control lines and verify ground terminal (PE) connections to maximize EMI filter efficiency.
• Verify 3-phase input voltage rating (380V–480V) prior to energizing the unit.

Maintenance Tips

• Periodically clean dust and debris from cooling vents and heat sink fins using clean, dry compressed air.
• Inspect terminal connection screws every 3 to 6 months to maintain tight electrical contacts.
• Monitor ambient panel enclosure temperatures to ensure operating conditions stay below 50°C.

Safety Instructions

• Always isolate input AC power and wait at least 10 minutes for internal capacitors to discharge before touching electrical connections.
• Never connect input AC main line power directly to output terminals U, V, and W.
• Installation and parameter tuning must be performed by certified technicians or experienced electrical engineers.
