Installation Guide

• Verify that your drive or control cabinet belongs to the System 3/5/6 family before you order this fan.
• Switch off the CNC and isolate the cabinet power before you touch any wiring.
• Photograph the fan mounting and cable routing so reassembly stays straightforward.
• Unbolt the old axial fan and lift it clear of the drive assembly.
• Clean dust from the fan shroud, because blocked airflow raises drive temperatures.
• Fit the A02B-0047-C920 unit, align the mounting holes, and tighten the screws evenly.
• Reconnect the fan leads, restore power, and confirm steady airflow with no vibration.
• Inspect the fan every few months and clear debris to protect drive electronics.
