GE Fanuc IC697ACC720 – Series 90-70 Rack Blanking/Slot Filler for Clean Airflow and Slot Protection

The GE Fanuc IC697ACC720 is an accessory for the Series 90-70 platform, typically used as a single‑slot blanking/filler solution on IC697 racks. From my experience, keeping unused slots covered helps stabilize airflow across populated modules, reduces dust ingress, and maintains EMC shielding inside the cabinet. If you’re maintaining a legacy 90‑70 system and you’ve got open slots in an IC697CHSxxx rack, this part is a simple, low-cost way to keep the backplane protected and the enclosure tidy.

One thing I appreciate is how straightforward it is—no wiring, no addressing, no firmware. You fit it, secure it, and you’re done. It sounds trivial, but in many cases it prevents nuisance over‑temperature alarms and dust buildup around contacts and connectors. A maintenance lead at a beverage plant told us they added fillers during a shutdown and “saw fewer intermittent faults through the summer heat,” which seems to be a common outcome when airflow is balanced properly.

Installation & Maintenance

• Cabinet & environment – Use inside an enclosure meeting your site’s ingress and ventilation requirements. Keep clear airflow paths across modules.
• Mounting – Power down the rack before fitting. Insert the filler into the slot guides and secure per the rack’s hardware (captive screws where provided).
• Wiring – Not applicable; ensure nearby module cabling is strain‑relieved and not obstructing airflow.
• Safety – Observe ESD precautions; avoid touching backplane connectors. Verify the filler is fully seated and mechanically stable.
• Routine care – Periodically inspect for loosened hardware and dust. Clean with a dry, lint‑free cloth. No calibration or firmware actions are required.

Quality & Certifications

• Designed for use within the GE Fanuc Series 90‑70 ecosystem, which typically aligns with CE and UL practices for industrial control equipment.
• RoHS status can vary by production lot and region; documentation on request.
