Critical Precautions
-
ESD Protection: Always wear a grounded wrist strap.
-
DC Polarity (SS): Solid-state outputs are DC-only and polarity-sensitive .
-
SS Overcurrent: If output exceeds 8.5A, LED flashes red—persistent overcurrent triggers bus fault.
-
SS Voltage Limit: Do not exceed 48VDC.
-
High-Voltage/Current Hazard (Relay): Relay outputs switch 115VAC/15A—lethal. Use proper insulation.
-
Relay Inductive Derating: For inductive loads, derate from 15A to 11A .
-
RTD Wiring: Use 3-wire Pt100 RTDs.
-
AI Model Learning: Requires 120-hour initial learning—do not interrupt power.
-
Fan Health Baseline: 14-day baseline required—warnings disabled during this period.
-
Quad-Redundant Paths: All four paths must be connected for full fault tolerance.
-
Cyber-Hardening: AES-512 encryption must be enabled via Mark V software.
-
No Hot-Swap: Always depower the rack before insertion/removal.
-
CPU Compatibility: Requires Mark V CPU firmware v9.5 or higher for full features.
-
Power Supply: Draws 10.0A on +5V rail—power supply upgrade is mandatory.
