Applicable Industries

Installation Requirements

1. Mount to standard 35 mm DIN rail or flat steel base plate with M4 mounting bolts
2. AC voltage sensing cables must be shielded twisted-pair with single-end shield grounding
3. Separate wiring ducts for high-voltage AC measurement lines and DC control power wiring
4. Install 5 A circuit breaker protection on 24 V DC power supply input terminal
5. RS485 communication cable must use dedicated twisted-pair fieldbus cable with bus-end termination resistor

Usage Notes

1. All three-phase voltage inputs must be wired in matching phase sequence to avoid synchronization failure
2. Complete parameter backup via Modbus software before module replacement or firmware update
3. Conduct full synchronization performance test after every genset governor/AVR overhaul
4. Avoid mounting within 200 mm of large AC contactors or variable frequency drives
5. Store spare controllers in temperature-controlled dry environment to prevent PCB corrosion
