This manual describes the functions, technical parameters, installation, operation, and Modbus‑RTU communication of the KPM75 energy quality analyzer.
The KPM75 energy quality analyzer from XJ Information provides three‑phase voltage, current, power, energy, power‑factor, frequency, harmonic analysis and event recording. It supports both star and delta wiring, offers relay outputs, digital inputs, analog outputs and a built‑in RS‑485 Modbus interface.
The document explains how to install the device, configure parameters (including password 6666), operate the five front‑panel keys, and use the communication protocol. Safety warnings emphasize professional installation and isolation before any work. This manual is written in Chinese.
