Description

The BECKHOFF C9900-M406 is a keyboard shelf designed for CP3xxx multi-touch Control Panels and Panel PCs.

The shelf mounts below compatible CP3x12 through CP3x24 devices. It provides a working surface for a standard PC keyboard during commissioning, configuration, and software updates.

An integrated USB socket is located at the rear of the shelf for keyboard connection. The USB socket is specified with IP65 protection.

Excess keyboard USB cable can be wrapped around the bracket underneath the shelf. The coated aluminum construction matches the design of compatible Beckhoff Control Panels.

During normal machine operation, the C9900-M406 can also serve as a toolboard while the operator uses the multi-finger touch interface.

The IP65 specification applies to the integrated rear USB socket. It should not be interpreted as an independently stated protection rating for the complete shelf assembly.

Installation Guidelines

1. Confirm that the required Control Panel or Panel PC is within the supported CP3x12 through CP3x24 range.

2. Specify the C9900-M406 when ordering the compatible Control Panel or Panel PC.

3. Confirm the required mounting arrangement before finalizing the panel configuration.

4. Inspect the shelf and USB connection area before commissioning.

5. Route the keyboard cable without creating tension at the USB connection.

6. Use the underside bracket to manage excess keyboard cable.

7. Verify that the installed shelf does not interfere with surrounding machine components.

8. Confirm unobstructed operator access before putting the machine into normal operation.

Commissioning Recommendations

Connect the required keyboard through the integrated rear USB socket after the Panel PC or Control Panel installation is complete.

Confirm normal keyboard communication before configuration or software-maintenance work begins.

Route excess cable around the provided underside bracket to reduce loose cabling around the operator station.

After commissioning, remove unnecessary temporary equipment and confirm that the shelf area remains clear of items that could interfere with machine operation.

Replacement and Procurement Considerations

The C9900-M406 should be identified by its complete order identifier before procurement.

Compatibility should be checked against the exact Control Panel or Panel PC configuration. The official ordering information specifies CP3x12 through CP3x24 applications.

The C9900-M406 is specified as an option ordered together with the associated Control Panel or Panel PC. This ordering condition should be considered when planning replacements or new installations.
