Field Installation Guidelines

• Verify the module part number, GDC806A1001 designation, and 3BHE028761R1001 identification before installation.
• Confirm the 24 VDC supply polarity and electrical characteristics before energizing the module.
• Keep 5 VDC signal wiring separated from high-current switching and power semiconductor conductors where practical.
• Route communication wiring according to the applicable CAN, Modbus, or ProfiNet physical-layer requirements.
• Maintain the specified isolation boundaries and do not bypass galvanic isolation through unintended cable shields, bonding paths, or auxiliary wiring.
• Connect cable shields and protective earth according to the system grounding design and ABB installation documentation.
• Provide mechanical support appropriate for the approximately 120 mm x 100 mm x 25 mm module dimensions.
• Verify connector engagement and wiring continuity before applying power or connecting the module to gate-drive circuitry.
• Do not substitute communication interfaces or firmware configurations without confirming compatibility with the installed control system.
