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.

1 Safety Information
1.1 Warnings, Cautions and Notes
1.2 Electrical Safety - general warning
The voltages used in the drive can cause severe electrical shock and/or burns, and
could be lethal. Extreme care is necessary at all times when working with or adjacent to
the drive.
Specific warnings are given at the relevant places in this guide.
1.3 System design and safety of personnel
The drive is intended as a component for professional incorporation into complete
equipment or system. 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 equipment which can cause injury.
System design, installation, commissioning and maintenance must be carried out by
personnel who have the necessary training and experience. They must read this safety
information and this guide carefully.
The STOP and START controls or electrical inputs of the drive must not be relied
upon to ensure safety of personnel. They do not isolate dangerous voltages from
the output of the drive or from any external option unit. The supply must be
disconnected by an approved electrical isolation device before gaining access to
the electrical connections.
The drive is not intended to be used for safety-related functions.
Careful consideration must be given to the function of the drive which might result in a
hazard, either through its intended behaviour or through incorrect operation due to a
fault. In any application where a malfunction of the drive or its control system could lead
to or allow damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk - for example, an over-speed
protection device in case of failure of the speed control, or a fail-safe mechanical brake
in case of loss of motor braking.
1.4 Environmental Limits
Instructions within the supplied data and information within the Digidrive SK Technical
Data Guide regarding transport, storage, installation and the use of the drive must be
complied with, including the specified environmental limits. Drives must not be
subjected to excessive physical force.
A Warning contains information, which is essential for avoiding a safety hazard.

1.5 Access
Access must be restricted to authorised personnel only. Safety regulations which apply
at the place of use must be complied with.
The IP (Ingress Protection) rating of the drive is installation dependant. For further
information, refer to the Digidrive SK Technical Data Guide.
1.6 Compliance and regulations
The installer is responsible for complying with all relevant regulations, such as national
wiring regulations, accident prevention regulations and electromagnetic compatibility
(EMC) regulations. Particular attention must be given to the cross-sectional areas of
conductors, the selection of fuses and other protection, and protective earth (ground)
connections.
The Digidrive SK EMC Guide contains instructions for achieving compliance with
specific EMC standards.
Within the European Union, all machinery in which this product is used must comply
with the following directives:
98/37/EC: Safety of machinery
89/336/EEC: Electromagnetic compatibility
1.7 Motor
Ensure the motor is installed in accordance with the manufacturer's recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of a drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. The motor should be fitted with a protection thermistor. If necessary, an
electric force vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor.
The default values in the drive should not be relied upon.
It is essential that the correct value is entered into parameter 06, motor rated current.
This affects the thermal protection of the motor.
1.8 Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering.
1.9 Electrical installation
1.9.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may
be lethal:
• AC supply cables and connections
• DC bus, dynamic brake cables and connections
• Output cables and connections
• Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and must not be
touched.

Information
1.9.2 Isolation device
The AC supply must be disconnected from the drive using an approved isolation device
before any cover is removed from the drive or before any servicing work is performed.
1.9.3 STOP function
The STOP function does not remove dangerous voltages from the drive, the motor or
any external option units.
1.9.4 Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the
AC supply has been disconnected. If the drive has been energised, the AC supply must
be isolated at least ten minutes before work may continue.
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual
fault conditions, it is possible that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output terminals. If the drive has failed
in a manner that causes the display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult LEROY-SOMER or their authorised
distributor.
1.9.5 Equipment supplied by plug and socket
Special attention must be given if the drive is installed in equipment which is connected
to the AC supply by a plug and socket. The AC supply terminals of the drive are
connected to the internal capacitors through rectifier diodes which are not intended to
give safety isolation. If the plug terminals can be touched when the plug is disconnected
from the socket, a means of automatically isolating the plug from the drive must be used
(e.g. a latching relay).
1.9.6 Ground leakage current
The drive is supplied with an internal EMC filter capacitor fitted. If the input voltage to
the drive is supplied through an ELCB or RCD, these may trip due to the ground
leakage current. See section 4.3.1 Internal EMC filter on page 14 for further information
and how to disconnect the internal EMC capacitor.

If DIN rail mounting is used in an installation where the drive is to be subjected to shock
or vibration, it is recommended that the bottom mounting screws are used to secure the
drive to the back plate.
If the installation is going to be subjected to heavy shock and vibration, then it is
recommended that the drive is surface mounted rather than DIN rail mounted.
NOTE
The DIN rail mounting mechanism has been designed so no tools are required to install
and remove the drive from a DIN rail. Please ensure the top mounting lugs are located
correctly on the DIN rail before installation is initiated.
NOTE
