Installation & Maintenance Guide

Installation Requirements:

• Mount vertically on a flat, non-combustible surface inside a dust-protected, well-ventilated control panel.
• Maintain sufficient clearance above and below the unit for unobstructed cooling airflow; side-by-side mounting is supported.
• Ensure main utility power matches 380V-480V 3-Phase rating before making electrical connections.
• Properly connect a dedicated protective earth ground conductor to ensure electrical safety and EMC compliance.

Maintenance Tips:

• Periodically clean dust and debris from cooling fins using clean, dry compressed air to prevent thermal faults.
• Inspect terminal screws for correct tightness during routine plant shutdowns to avoid high-resistance hot spots.
• Keep cabinet doors closed and inspect intake fan filters routinely to maintain clean internal panel air.

Safety Instructions:

• Disconnect main AC input supply and wait at least 5 minutes for internal DC link capacitors to discharge fully before touching wiring.
• Electrical installation, parameter setting, and servicing must only be performed by qualified electrical personnel.
• Do not conduct megger or insulation resistance testing directly across drive power terminals.
