1 Introduction

1.1 Purpose of the Design Guide

This design guide introduces important aspects of the VLT
Advanced Harmonic Filters AHF 005/AHF 010 (referred to
as AHF) for VLT
describes harmonics and how to mitigate them, and it
provides installation instructions and guidance on how to
program the frequency converter.
The technical data and information on the connection
conditions are on the nameplate and in the documen-
tation. Always observe the recommendations and
instructions in this document.
Danfoss technical literature is also available online at
drives.danfoss.com/knowledge-center/technical-documen-
tation/.

1.2 Intended Use

The filters are components designed for installation in
electrical systems or machinery.
When installing in machines, commissioning of the filters
(that is starting of operation as directed) is prohibited until
it is proven that the machine complies with the Machinery
Directive 2006/42/EC. Observe EN 60204.
