This manual describes the CDI‑BR series energy braking units, which are used with inverters in elevators, hoists, mining lifts, centrifuges, oil‑field pumps and other applications. It explains how the unit dissipates regenerated energy as heat to provide braking torque and ensure safe operation of the drive system.
The document covers product specifications, terminal layout, wiring diagrams, installation dimensions, main‑circuit connection methods, cable sizing, and a troubleshooting guide with error codes and common fault remedies. This manual is written in Chinese.
