Installation Guidelines

• Mounting: Ensure the panel is installed in a cut-out with the provided gasket to maintain the required IP protection rating on the front side.
• Ventilation: Maintain adequate clearance behind the unit to prevent overheating, especially in enclosed control cabinets.
• Grounding: Use the designated functional ground terminal to ensure electromagnetic compatibility (EMC) and reduce electrical noise interference.
• Cable Routing: Separate signal cables (Profinet/Profibus) from high-voltage power lines to minimize potential signal degradation.
• Cleaning: Use a damp, soft cloth with a mild cleaning agent for the touch screen surface; avoid abrasive materials that could scratch the resistive overlay.
