Introduction

1 Introduction

1.1 Purpose of the Manual

The purpose of this manual is to provide information for
the installation and operation of a VLT
FC 103 Low Harmonic. The manual includes relevant safety
information for installation and operation.
chapter 1 Introduction, chapter 2 Safety,
chapter 3 Mechanical Installation, and chapter 4 Electrical
Installation introduce the unit functions and cover proper
mechanical and electrical installation procedures. There are
chapters on start-up and commissioning, applications and
basic troubleshooting. Chapter 8 Specifications provides a
quick reference for ratings and dimensions, as well as other
operating specifications. This manual provides a basic
knowledge of the unit and explains set-up and basic
operation.

1.3.1 Intended Use

®
Refrigeration Drive
A frequency converter is an electronic motor controller
that converts AC mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
frequency converter can vary the speed of the motor in
response to system feedback, such as with position sensors
on a conveyor belt. The frequency converter can also
regulate the motor by responding to remote commands
from external controllers.
The frequency converter:
Operation and monitoring functions are available as status
indications to an outside control system or serial communi-
cation network.
A low harmonic drive (LHD) is a single unit that combines
the frequency converter with an advanced active filter
(AAF) for harmonic mitigation. The frequency converter
and filter are packaged together in an integrated system,
but each functions independently. In this manual, there are
separate specifications for the frequency converter and the
filter. Since the frequency converter and filter are in the
same enclosure, the unit is transported, installed, and
operated as a single entity.
