1 Introduction
1.1 Purpose of the Design Guide
This design guide for VLT
®
Refrigeration Drive FC 103
frequency converters is intended for:
•
Project and systems engineers.
•
Design consultants.
•
Application and product specialists.
The design guide provides technical information to
understand the capabilities of the frequency converter for
integration into motor control and monitoring systems.
The purpose of the design guide is to provide design
considerations and planning data for integration of the
frequency converter into a system. The design guide caters
for selection of frequency converters and options for a
diversity of applications and installations.
Reviewing the detailed product information in the design
stage enables developing a well-conceived system with
optimal functionality and efficiency.
