Safety Information

The SM-EZMotion module and its associated drive are intended as components for professional incorporation into complete
equipment or systems. If installed incorrectly the drive may present a safety hazard. The drive uses high voltages and
currents, carries a high level of stored electrical energy and is used to control mechanical equipment that can cause injury.
Close attention is required to the electrical installation, commissioning and maintenance must be carried out by personnel who
have the necessary training and experience, They must read this safety information and User Guide carefully.
Careful consideration must be given to the functions of the drive and solutions module, which might result in a hazard, either
through their intended functions e.g. auto-start or through incorrect operation due to a fault or trip e.g. stop/start, forward/
reverse, maximum speed, loss of communications link.
In any application where a malfunction of the drive or solutions module could lead to damage, loss or injury, a risk analysis
must be carried out and where necessary further measures taken to reduce the risk. To ensure mechanical safety additional
safety devices such as electro-mechanical interlocks may be required. The drive must not be used in a safety critical
application without high-integrity protection against hazards arising from a malfunction.
General Information
The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent of incorrect installation or
adjustment of the optional operation parameters of the equipment or from mismatching the variable speed drive (drive) with
the motor.
The contents of this guide are believed to be correct at the time of printing. In the interests of a commitment to a policy of
continuous development and improvement, the manufacturer reserves the right to change the specification of the product or
its performance, of the contents of this guide, without notice.
All rights reserved. No parts of this guide may be reproduced or transmitted in any form of by any means, electrical or
mechanical including photocopying, recording or by an information storage or retrieval system, without permission in writing

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 on
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 this product to function differently. This may also apply to drives returned from a Control
Techniques Service Centre. If there is any doubt, contact a Control Techniques Drive Centre.
Safety of Machinery
Within the European Union all machinery in which this product is used must comply with Directive 89/392/EEC, Safety of
Machinery.
The product has been designed and tested to a high standard, and failures are very unlikely. However the level of integrity
offered by the product's control function – for example stop/start, forward/reverse and maximum speed – is not sufficient for
use in safety-critical applications without additional independent channels of protection. All applications where malfunction
could cause injury or loss of life must be subject to a risk assessment, and further protection provided where needed.
General warning
Failure to follow safe installation guidelines can cause death or serious injury. The voltages used in this unit can cause
severe electric shock and/or burns, and could be lethal. Extreme care is necessary at all times when working with or
adjacent to this equipment. The installation must comply with all relevant safety legislation in the country of use.
AC supply isolation device
The AC supply must be removed from the drive using an approved isolation device or disconnect before any servicing work
is performed, other than adjustments to the settings or parameters specified in the manual. The drive contains capacitors
which remain charged to a potentially lethal voltage after the supply has been removed. Allow at least 6 minutes for the
Epsilon 205, 3 minutes for Epsilon 202/203 and 30 seconds for E Series drives after removing the supply before carrying
out any work which may involve contact with electrical connections to the drive.
Products connected by plug and socket
A special hazard may exist where the drive is incorporated into a product which is connected to the AC supply by a plug
and socket. When unplugged, the pins of the plug may be connected to the drive input, which is only separated from the
charge stored in the bus capacitor by semiconductor devices. To avoid any possibility of electric shock from the pins, if they
are accessible, a means must be provided for automatically disconnecting the plug from the drive (e.g., a latching
contactor).
Grounding (Earthing, equipotential bonding)
The drive must be grounded by a conductor sufficient to carry all possible fault current in the event of a fault. The ground
connections shown in the manual must be followed.
Fuses
Fuses protection must be provided at the input in accordance with the instructions in the manual.
