Measurement and Performance Notes

• This unit does not measure range, frequency response, or sensitivity, because it is a cooling fan.
• Linear response, resolution, and linearity do not apply to a fan assembly of this type.
• Temperature range depends on the host cabinet and the airflow path around the amplifiers.
• Environmental tolerance comes from the machine enclosure, not from the fan unit itself.
• Noise immunity relies on the CNC cabinet grounding and the original FANUC wiring layout.

Installation Guide

• Power down the CNC cabinet and lock out the main supply before you start work.
• Confirm the mounting cutout matches the original panel-mount fan footprint.
• Remove the old fan unit and keep the original screws, grille, and connector for reuse.
• Seat the A02B-0047-C901 fan unit into the panel opening and align the fixing holes.
• Tighten the screws evenly, then reconnect the fan leads to the original terminal points.
• Check that the blades spin freely and that no cable touches the rotating parts.
• Restore power and verify airflow direction toward the servo amplifiers and PCBs.
• Monitor cabinet temperature for the first hour of operation after the swap.
