Main Functions

1. High‑precision signal scaling and conditioning for DC‑link voltage, phase current and power‑device temperature signals.
2. Galvanic isolation between high‑voltage power section and low‑voltage control rack, suppress strong electromagnetic interference.
3. Hardware pre‑monitoring: detect over‑voltage, under‑voltage, over‑current and over‑temperature, output fast fault trigger signal.
4. Send processed measuring data to main processor via back‑plane bus for closed‑loop control and fault recording.
5. Board‑level self‑diagnosis: detect sampling‑circuit abnormality and board power‑supply failure, report fault codes to converter system.
6. LED status indication:
   • Green LED：Power supply normal, board logic healthy
   • Yellow LED：Sampling signal active
   • Red LED：Sampling channel fault / power‑unit protection fault / board hardware fault

Installation & Wiring Requirements

1. Cut off cabinet total power before installation or replacement. Insert XVC767AE102 into assigned rack slot and tighten mounting screws. Hot‑swap is strictly forbidden.
2. Connect voltage/current sampling cables and temperature‑sensor cables strictly per wiring drawing; separate high‑power cables and weak‑signal cables to reduce electromagnetic interference.
3. Cabinet protective grounding shall comply with ABB ACS6000 / Megadrive‑LCI grounding specification.
4. After replacement, confirm firmware compatibility, complete signal calibration and protection‑function simulation test before commissioning.
5. Replacement note: Cross‑version substitution requires hardware‑firmware compatibility validation
