This document is an instruction manual for the TH4108-M/A inverter remote controller, which describes its features and appearance. The controller can remotely operate the inverter, enabling functions such as start, stop, accelerate, decelerate, and forward/reverse rotation, and display status information such as set frequency and actual frequency. It features optically isolated RS485 communication, strong anti-interference capability, and protection against lightning and static electricity.
The TH4108-M/A remote controller provides RS485 communication up to 1200 m, allowing start, stop, speed adjustment and direction control of a frequency converter. It supports both wired and optional wireless modules and offers four external I/O ports for additional control functions.
The manual details the physical layout, button and LED functions, power supply options for M‑type (9‑36 V) and A‑type (220 V AC), wiring diagrams, parameter settings, operation procedures, fault codes and safety precautions for reliable installation and use. This manual is written in Chinese.
