Installation & Maintenance Guide

Installation Requirements:

1. Mounting Position: Install vertically on a flat, heat-resistant mounting plate inside a ventilated industrial control cabinet.
2. Clearance Spacing: Maintain a minimum vertical clearance of 100mm above and below the drive to ensure unhindered thermal airflow through the heatsink.
3. Power Wiring: Wire 380–500V 3-phase incoming main power (R/L1, S/L2, T/L3) through a correctly rated molded case circuit breaker (MCCB) and semiconductor fuses. Wire output motor terminals (U/T1, V/T2, W/T3) using shielded 4-core copper power cables.
4. Earthing/Grounding: Connect a direct low-impedance ground wire between the drive PE lug, enclosure mounting plate, and motor frame to prevent noise interference and electrical shock.

Maintenance Tips:

• Dust Management: Blow clean, dry compressed air (max 2 bar) through the heatsink fins every 3–6 months to prevent thermal accumulation.
• Cooling Fan Inspection: Periodically check that internal cooling fans rotate freely without abnormal acoustic vibration or friction.
• Terminal Verification: Retighten all power and control screw terminals during routine maintenance to prevent loose, high-resistance hot spots.

Safety Instructions:

• Capacitor Discharge: Disconnect all main power connections and wait at least 15 minutes before touching electrical terminals to allow internal high-voltage DC bus capacitors to fully discharge.
• Insulation Testing: Never perform Megger high-voltage insulation tests directly on VFD power terminals; disconnect motor leads completely prior to testing motor insulation resistance.
