Product Overview
The Siemens 6AV3678-3XC30-XC30 SIMATIC HMI Service Pack is a maintenance spare-parts package associated with Siemens SIMATIC HMI pushbutton panels. The service pack reference 6AV3678-3XC30 is listed for PP7, PP17 I and PP17 II panel families, with components intended to support servicing and restoration of the operator panel’s installation and electrical connections.
For maintenance teams working with established machine-control installations, a service pack can be useful when a panel needs to be removed and refitted or when its mounting and terminal components require replacement. Having the appropriate service parts available helps avoid sourcing individual components separately during a planned maintenance shutdown.
The service package is associated with mounting seals, mounting clamps and electrical terminal blocks. These parts serve different purposes: the seal supports the panel’s mounting interface, the clamps secure the panel in its installation opening, and the terminal blocks provide connection points for the applicable electrical circuits.
The supplied product title includes the extended reference 6AV3678-3XC30-XC30. The documented service-pack reference is 6AV3678-3XC30, so the exact ordering reference and package contents should be checked against the equipment being serviced before the parts are used.

Product Features
- Panel mounting parts: Includes service components associated with mounting and securing compatible HMI panels.
- Mounting seal: Supports the sealing interface between the operator panel and its installation opening.
- Mounting clamps: Secure the panel in its mounting position.
- Electrical terminal blocks: Provide connection points for the applicable power and I/O wiring.
- Maintenance-oriented package: Groups specified service components for panel maintenance.
- Equipment-specific selection: Compatibility depends on the HMI panel family and the required service configuration.
- Spare-parts identification: The order reference helps maintenance teams distinguish the intended service package from other SIMATIC HMI accessories.
Working Principle
Unlike an HMI panel or controller, the service pack does not execute control logic, display process data or communicate with a PLC. It contains replacement parts used when maintaining the physical installation and electrical connections of a compatible operator panel.
The mounting seal sits at the panel-to-enclosure interface, while the mounting clamps hold the panel in place. Terminal blocks provide the connection points needed for the applicable electrical circuits. Each component must be installed in its designated position to maintain the intended mechanical fit and electrical connection.
During panel replacement or refurbishment, worn seals, damaged clamps or compromised terminal connections may need attention. Using the correct service parts helps restore the original mounting arrangement without substituting components based only on appearance.
The service pack itself does not establish panel compatibility with a PLC or replace the HMI’s operating software. Those requirements depend on the installed panel, its electrical configuration and the automation system in which it operates.
Role in a SIMATIC HMI Operator Station
The service pack supports the physical installation and electrical connection of a compatible SIMATIC HMI pushbutton panel. The panel remains the operator interface; the service parts help maintain its mounting and connection arrangements.

Installation and Maintenance
- Verify the order reference: Check the supplied 6AV3678-3XC30-XC30 designation against the required service-pack reference and the installed panel.
- Identify the HMI panel: Confirm whether the equipment belongs to the supported PP7, PP17 I or PP17 II family.
- Isolate the electrical supply: Follow the machine’s safety procedure before disconnecting panel wiring or removing terminal blocks.
- Document existing connections: Record terminal assignments and wire identification before dismantling the panel.
- Remove the panel carefully: Release the mounting clamps and withdraw the panel without damaging the enclosure opening or connected wiring.
- Inspect the mounting interface: Check the seal, enclosure opening and clamp contact points for damage or contamination.
- Check the terminal blocks: Inspect the applicable connection components for cracks, damaged contacts or other signs of deterioration.
- Match replacement components: Confirm that each service part corresponds to the intended panel and connection arrangement.
- Fit the mounting seal: Position the seal correctly at the designated interface, avoiding twists, gaps or trapped debris.
- Reconnect the wiring: Install the applicable terminal blocks and restore each conductor according to the documented wiring arrangement.
- Secure and test the panel: Refit the mounting clamps, restore power under the approved procedure and check the panel’s basic operation.
- Record the service work: Document the replacement parts, panel identification and any wiring or mounting issues found during maintenance.
