Preface
This manual provides all the information on the FRENIC-MEGA series of inverters including its operating
procedure, operation modes, and selection of peripheral equipment. Carefully read this manual for proper use.
Incorrect handling of the inverter may prevent the inverter and/or related equipment from operating correctly,
shorten their lives, or cause problems.
The table below lists the other materials related to the use of the FRENIC-MEGA. Read them in conjunction with
this manual as necessary.

Guideline for Suppressing Harmonics in Home Electric and General-purpose Appliances
Our three-phase, 200 V class series inverters of 3.7 kW or less (FRENIC-MEGA series) were the products of
which were restricted by the "Guideline for Suppressing Harmonics in Home Electric and General-purpose
Appliances" (established in September 1994 and revised in October 1999) issued by the Ministry of Economy,
Trade and Industry. The above restriction, however, was lifted when the Guideline was revised in January 2004.
Since then, the inverter makers have individually imposed voluntary restrictions on the harmonics of their products.
We, as before, recommend that you connect a reactor (for suppressing harmonics) to your inverter. As a reactor,
select a "DC REACTOR" introduced in this manual. For use of the other reactor, please inquire of us about
detailed specifications.
