Installation & Maintenance Guide

Installation Requirements:

• Mount vertically on a flat, non-flammable surface inside a clean, well-ventilated control cabinet.
• Ensure clear surrounding clearance of at least 50 mm on both sides and 100 mm above and below the unit for natural cooling airflow.
• Connect 380–500V 3-phase mains lines to terminals L1, L2, L3 and motor leads to output terminals U, V, W with secure earthing.
• Use shielded power and control cables to suppress high-frequency electromagnetic noise.

Maintenance Tips:

• Clean cooling fan blades and heat sink cooling fins periodically to prevent dust buildup.
• Tighten terminal block screws regularly to avoid loose connections caused by machinery vibration.
• Inspect real-time operational logs and internal drive temperature via the keypad terminal.

Safety Instructions:

• Always disconnect main AC power and wait at least 15 minutes for internal DC bus capacitors to discharge fully before touching wiring terminals.
• Ensure protective ground wires are connected tightly before turning power ON.
• Installation, wiring, and parameter setup must strictly be performed by qualified electrical technicians.
