Product Deep Dive
When you are staring at a cracked HMI screen on a production line, the last thing you want to do is replace the entire $3,000 Panel PC unit. The AUTOMATION 5AC600.FLAP-K11 is the specific front flap designed to solve this exact problem for B&R APC620 series panels. It acts as the primary interface shield, protecting the display and touch layer from physical impact and process contaminants.This part is essentially the “faceplate” of your machine’s brain. In my experience, these flaps take the brunt of the abuse—chemical splashes, accidental tool drops, and constant finger pressure. The 5AC600.FLAP-K11 is engineered to maintain the unit’s IP65 rating, ensuring that even if the outer layer gets scratched or hazed over time, the sensitive electronics behind it remain hermetically sealed. It’s a relatively low-cost component that saves you from a massive hardware replacement bill.

Installation & Wiring Guide
Replacing a front flap is mechanically simple but requires patience to avoid damaging the LCD ribbon cables or the new gasket.
🛠️ Phase 1: Preparation (Estimated Time: 15 minutes)
- Power Down: Shut down the Panel PC via software, then cut the 24V DC power supply.
- Cleanliness: Wipe down the area around the panel. You don’t want dust falling behind the bezel when you open it up.
- Tools: You will likely need a Torx T10 or T15 screwdriver, and a plastic pry tool (guitar pick style) to avoid scratching the chassis.
🔧 Phase 2: Removal of Old Flap (Estimated Time: 20 minutes)
- Locate Fasteners: Check the sides or bottom edge of the current flap. On the APC620 series, there are often hidden clips or small screws holding the flap to the rear housing.
- Separation: Gently pry the flap away from the rear housing. Caution: Do not pull it all the way off immediately. There may be a ground wire or a sensor cable connecting the flap to the chassis (for touch grounding).
- Disconnect: If there is a grounding strap, unscrew it carefully. Set the old flap aside.
🔩 Phase 3: Installation of New Flap (Estimated Time: 20 minutes)
- Gasket Check: Inspect the seal on the AUTOMATION 5AC600.FLAP-K11. Ensure the foam gasket is intact and sticky. This is what gives you your IP65 rating.
- Alignment: Connect any grounding wires first. Then, align the clips on the new flap with the slots on the rear housing.
- Seating: Press firmly around the edges until you hear the clips snap into place. If there are screws, tighten them evenly—don’t overtighten, or you might crack the plastic frame.
⚡ Phase 4: Power-up & Verification (Estimated Time: 10 minutes)
- Visual Inspection: Ensure there are no gaps between the flap and the housing. It should look flush.
- Power On: Restore 24V power and boot the system.
- Touch Test: Open a test screen or HMI runtime. Touch every corner of the screen. If the touch is unresponsive in one corner, the flap might be pressing too hard on the bezel, or the grounding isn’t seated right.
