Field Installation Guidelines
- Isolate the relevant control-system power sources and follow the site’s lockout and verification procedures before removing the board.
- Record connector positions, jumper settings, and board identification markings before disconnection.
- Inspect connectors, pin contacts, component surfaces, and the PCB for physical damage or contamination.
- Use appropriate electrostatic discharge precautions when handling the assembly.
- Confirm the replacement board’s full part number, revision, and configuration against the installed hardware and system documentation.
- Restore wiring and jumpers according to the applicable GE drawings. Do not infer electrical settings from physical similarity alone.
- Complete the required continuity, excitation-circuit, and system functional checks before returning the control system to service.
