Supplemental instructions for the DriveIT low voltage AC drive ACS 400V, providing information on installation, maintenance, and precautions. The drive features warnings about dangerous voltages, automatic startup after power interruption, parallel control terminal connection, and high temperature warning.
This supplement provides additional safety warnings, installation guidance, and operational details for the ABB ACS 400V low‑voltage AC drive. It is intended for use together with the main ACS 400 User Manual and is especially relevant for HVAC applications.
Key topics include safety precautions for handling dangerous voltages, mounting and wiring of the RFI filter, I/O configuration, various control modes (0‑10 V, PID, start/stop), and EMC requirements. The document also lists maximum motor cable lengths and compliance with relevant standards.
| Frame size R1 and R2 power range | 3.0 – 11 kW |
|---|---|
| Frame size R3 and R4 power range | 15 – 37 kW |
| Maximum motor cable length (with input filter) | 30 m |
| Switching frequency options | 4 kHz or 8 kHz |
| EMC filter compliance standards | EN61800‑3, First Environment, Restricted Distribution, AS/NZS 2064 |
Only a competent electrician may install the ACS 400V.
Dangerous voltages are present when the mains supply is connected, and even after power‑down there may be hazardous voltages at various terminals.
The motor cable length should not exceed 30 m when an input filter is used.
The RFI filter must comply with EN61800‑3, First Environment, Restricted Distribution, and AS/NZS 2064 Class A requirements.
