Main Functions

1. Real‑time sampling and monitoring of medium‑voltage inverter output voltage.
2. Fast detection of output short‑circuit and sudden voltage drop fault, hardware‑level rapid response.
3. Output fault trigger signal to main control board, trigger drive trip sequence to protect power unit.
4. Hardware fault latch function, keep fault status until manual reset.
5. Board self‑diagnosis: detect sampling circuit abnormality and board power‑supply failure, report fault code to drive system.
6. LED status indication:
   • Green LED：Power supply normal, board logic healthy
   • Yellow LED：Voltage sampling signal active
   • Red LED：Short‑circuit fault / sampling channel fault / board hardware fault

Installation & Wiring Requirements

1. Cut off cabinet total power before installation or replacement. Insert XVC724BE102 into assigned rack slot and tighten mounting screws. Hot‑swap is strictly forbidden.
2. Connect high‑voltage sampling cables and fault‑signal 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 ACS2000 system grounding specification.
4. After replacement, confirm firmware compatibility, perform voltage sampling calibration and short‑circuit protection simulation test before commissioning.
5. Replacement note: Cross‑version substitution requires hardware‑firmware compatibility validation.
