This document is a declaration of conformity for the EU Electromagnetic Compatibility, which states that ACS 400 series frequency converters meet EN 61800-3 standard
This EC Declaration of Conformity states that ABB Frequency Converters of the ACS series (including ACS550, ACS350 and ACS800) meet the requirements of the ATEX directive and related EN standards. The document lists the applicable motor categories, temperature classes, and certification numbers for the compatible 3‑phase induction motors.
The declaration also specifies operating conditions such as ambient temperature limits (‑20 °C to +40 °C), duty frequency ranges (0‑90 Hz for ACS800, 5‑90 Hz for ACS350/ACS550), and the required motor loading derating curve. The CE marking year is 2005 and the document is signed by the product responsible for EEx and Marine Products.
| Duty frequency range (ACS800) | 0‑90 Hz |
|---|---|
| Duty frequency range (ACS350/ACS550) | 5‑90 Hz |
| Ambient temperature limit | -20 °C to +40 °C |
The ACS800 can operate over a duty frequency range of 0 to 90 Hz.
The ambient temperature must be kept between –20 °C and +40 °C.
