Installation & Maintenance Guide

Installation Requirements

• Install vertically inside an IP54 or NEMA-rated control enclosure to guard against moisture and conductive dust.
• Ensure adequate top and bottom clearance for proper heatsink airflow; side-by-side zero-clearance mounting is permitted.
• Use shielded power and control cables, ensuring proper 360-degree grounding clamp connections to minimize EMI/RFI interference.
• Verify input voltage matches 380V–480V 3-phase supply prior to applying power.

Maintenance Tips

• Clean dust accumulation from heat sink cooling fins and cooling fans using dry compressed air every 3 to 6 months.
• Inspect terminal block screw connections regularly to prevent heating due to vibration loose connections.
• Monitor ambient panel temperature to ensure it remains below 50°C during full continuous operation.

Safety Instructions

• Always disconnect main AC power and wait at least 10 minutes for DC bus capacitors to discharge before servicing wires.
• Ensure solid earthing/grounding (PE terminal) is connected according to local electrical codes.
• Only qualified engineers or trained technicians should perform wiring, parameter configuration, and maintenance.
