General Information

The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent 
or incorrect installation or adjustment of the optional parameters of the equipment or from 
mismatching the variable speed drive with the motor.
The contents of this guide are believed to be correct at the time of printing. In the interests of 
commitment to a policy of continuous development and improvement, the manufacturer reserves the 
right to change the specification of the product or its performance, or the content of the guide without 
notice.
All rights reserved. No parts of this guide may be reproduced or transmitted in any form or by any 
means, electrical or mechanical including, photocopying, recording or by an information storage or 
retrieval system, without permission in writing from the publisher.

Drive software version

This product is supplied with the latest version of user-interface and machine control software. If this 
product is to be used in a new or existing system with other drives, there may be some differences 
between their software and the software in this product. These differences may cause the product 
to function differently. This may also apply to drives returned from the LEROY-SOMER Service 
Centre.
If there is any doubt, please contact LEROY-SOMER.

Environmental Statement

LEROY-SOMER is committed to minimising the environmental impacts of its manufacturing 
operations and of its products throughout their life cycle. To this end, we operate an Environmental 
Management System (EMS) which is certified to the International Standard ISO 14001.
The electronic variable speed drives manufactured by LEROY-SOMER have the potential to save 
energy and (through increased machine/process efficiency) reduce raw material consumption and 
scrap throughout their long working lifetime. In typical applications, these positive environmental 
effects far outweigh the negative impacts of product manufacture and end-of-life disposal.
Nevertheless, when the products eventually reach the end of their useful life, they can very easily be 
dismantled into their major component parts for efficient recycling. Many parts snap together and can 
be separated without the use of tools, while other parts are secured with conventional screws. 
Virtually all parts of the product are suitable for recycling.
Product packaging is of good quality and can be re-used. Large products are packed in wooden 
crates, while smaller products come in strong cardboard cartons which themselves have a high-
recycled fibre content. If not re-used, these containers can be recycled. Polythene, used on the 
protective film and bags from wrapping product, can be recycled in the same way. LEROY-SOMER's 
packaging strategy favours easily recyclable materials of low environmental impact, and regular 
reviews identify opportunities for improvement.
When preparing to recycle or dispose of any product or packaging, please observe local legislation 
and best practice.
