5. Firmware – The “AAA” suffix indicates a specific firmware version; verify compatibility with your Mark V/VIe system.

6. Spares – Lead time typically 8–10 weeks; maintain a spare module for critical installations.

Precautions

• ESD Protection – Use wrist strap and anti-static handling during installation.

• Analog Input Wiring – Use shielded twisted-pair cables for voltage inputs; ground shields at the module end only.

• Analog Output Wiring – Ensure output loads are within the module’s drive capability (>2 kΩ min).

• Avoid Ground Loops – Connect earth lug directly to system ground with 6 mm² wire; avoid ground loops.

• Commissioning – Verify input readings with known signal sources and test outputs with dummy loads before field connection.

• Firmware Updates – Use only GE’s official tool for firmware updates.

• Periodic Inspection – Check for dust accumulation on heatsink and connector integrity annually; clean as needed.
