8. 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; ground shields at the module end only.

• Thermocouple Wiring – Use thermocouple-grade extension wire of the same type; avoid copper wire between sensor and module.

• Breakout Wiring – Ensure proper wiring termination at the breakout section; verify connections before applying power.

• Cold Junction Compensation – Ensure cold junction sensors are protected from external heat sources or drafts.

• Analog Output Wiring – For 4–20 mA outputs, ensure the loop resistance is within the module’s drive capability (750 Ω max).

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

• Input Burnout Detection – Configure burnout detection for 4–20 mA and thermocouple inputs.

• 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.
