Installation & Maintenance Guide

Installation Requirements:

• Install vertically inside an IP54-rated, properly ventilated electrical control cabinet to protect against dust and oil mist.
• Ensure adequate clearance space above, below, and around the unit for unrestricted cooling fan airflow.
• Provide solid 3-phase ground connections and use shielded motor power lines to reduce electromagnetic interference (EMI).

Maintenance Tips:

• Clean heat sink fins and internal cooling fans regularly using dry, low-pressure compressed air.
• Inspect terminal connection screws periodically to ensure vibration has not loosened wiring terminations.
• Monitor operating parameters and fault logs regularly on the digital keypad screen.

Safety Instructions:

• Always isolate incoming AC mains power and wait a minimum of 10 minutes for internal DC bus capacitors to discharge fully before touching terminals.
• Electrical installation, parameter programming, and commissioning must be conducted by qualified electrical engineers or technicians.
