Selection Guidelines & Precautions
-
Application Verification – Designed for integrated power management with enhanced diagnostics, predictive analytics, and SIL 2.
-
Physical Compatibility – 6HP wide, requires 1.5 adjacent slots.
-
Backplane Compatibility – Uses P1 and P2. If backplane lacks P2, diagnostic features unavailable.
-
Thermal Derating – Full output to 60°C; derate to 90% at 60–65°C, 80% at 65–70°C. Do not operate above 70°C.
-
SIL 2 Compliance – Follow GE safety manual GEI‑100988 for installation and proof‑test intervals.
-
Diagnostic Features – Access diagnostic data via backplane communication using GE Service Tool Software.
-
Spare Sourcing – Production ended in 2020. Request test report verifying outputs, diagnostic functions, predictive analytics, and event logging. Inspect for capacitor bulging or discoloration.
