Installation & Maintenance Guide

Installation Requirements:

• Mount the drive vertically on a flat panel inside a clean, well-ventilated enclosure to ensure natural convective airflow.
• Maintain standard clearance gaps above, below, and on both sides of the drive unit for adequate air circulation.
• Connect power lines using recommended input fuses and ground terminals firmly to mitigate electrical noise.
• Use shielded twisted-pair wiring for pulse command, analog voltage, and encoder communication terminals.

Maintenance Tips:

• Periodically clean heat sink cooling channels to prevent dust accumulation from impairing thermal dissipation.
• Regularly inspect terminal screws and quick-connect plugs (CN1, CN2, power) for firm contact.
• Monitor panel fan operation to ensure ambient temperature remains within recommended operating limits.

Safety Instructions:

• Always disconnect main power input before handling terminal wiring, connections, or internal fuses.
• Wait at least 10 minutes post power-off to ensure high-voltage internal capacitors have completely discharged.
• Never apply AC power directly to motor output terminals U, V, and W, as this will permanently damage internal IGBTs.
