Installation and Maintenance Guidelines
Mount the GE DS200TCQCG1AJD using standard DIN-rail clips or direct panel mounting in control cabinets. Ensure proper alignment with adjacent modules to maintain airflow—critical for heat dissipation in high-temperature environments. When replacing or upgrading, transfer PROM modules from the old board to preserve firmware configurations .
For maintenance:
- Inspect connector pins quarterly for corrosion, especially in humid environments.
- Verify jumper settings match system requirements after maintenance (refer to GE GEH-6226 manual for details) .
- Use compressed air to — remove dust from ventilation slots to prevent overheating.
