TD900 series inverters are high-quality multi-function low-noise inverters independently developed and produced by Emerson Network Power Co., Ltd.
This manual covers the safety regulations, product overview, installation and wiring procedures, and functional parameters for the Emerson TD900 series variable frequency drives. It is intended for installation engineers, maintenance staff, and designers.
The document also includes detailed function code tables, fault handling methods, routine maintenance steps, and warranty information, ensuring reliable operation and proper servicing of the drives. This manual is written in Chinese.
| Power rating | 22 kW |
|---|---|
| Input voltage | 3‑phase AC 380 V‑460 V |
| Output frequency range | 0‑650 Hz |
| Protection level | IP20 |
Because the output is a pulsed waveform, a digital multimeter will read about 450 V when the true RMS value is 380 V; the multimeter reading is therefore only an approximate value.
The warranty covers the drive itself for eighteen months from the manufacturing date.
Check the external wiring for errors, correct any issues, and then re‑apply power to restart the drive.
