NOTE
LEROY-SOMER reserves the right to modify the characteristics of its products at any time in order to incorporate the latest
technological developments. The information contained in this document may therefore be changed without notice.
LEROY-SOMER gives no contractual guarantee whatsoever concerning the information published in this document and cannot
be held responsible for any errors it may contain, nor for any damage resulting from its use.
CAUTION
For the user’s own safety, this VARMECA 14 motor must be connected to an approved earth ( terminal).
It is imperative that the equipment is supplied via an isolating device and a circuit-breaking device (power contactor) which can be
controlled by an external safety system (emergency stop, fault detector).
The VARMECA 14 motor is fitted with safety devices which, in the event of a fault, control stopping and thus stop the motor. The
motor itself can become jammed for mechanical reasons. Voltage fluctuations, and in particular power cuts, may also cause the
motor to stop.
The removal of the causes of the shutdown can lead to restarting, which may be dangerous for certain machines or installations.
In such cases, it is essential that the user takes appropriate precautions against the motor restarting after an unscheduled stop.
The VARMECA 14 motor is a component designed to be integrated in an installation or electrical machine. It is therefore the
responsibility of the user to take all necessary precautions to ensure that the system complies with current standards.
For safety reasons, LEROY-SOMER prohibits the use of VARMECA 14 for hoisting applications.
LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.

• Throughout the manual, this symbol warns
of consequences which may arise from
inappropriate use of the VARMECA 14, since electrical
risks may lead to material or physical damage as well as
constituting a fire hazard.
1 - General
Depending on their degree of protection, VARMECA 14
motors may contain moving parts, as well as hot surfaces,
during operation.
Unjustified removal of protection devices, incorrect use, faulty
installation or inappropriate operation could represent a
serious risk to personnel, animals and equipment.
For further information, consult the manual.
All work relating to transportation, installation, commissioning and
maintenance must be performed by experienced, qualified
personnel (see IEC 364, CENELEC HD 384, or DIN VDE 0100
and national specifications for installation and accident
prevention).
In these basic safety instructions, qualified personnel means
persons competent to install, mount, commission and operate
the product and possessing the relevant qualifications.
2 - Use
VARMECA 14 motors are components designed for
integration in installations or electrical machines.
When integrated in a machine, commissioning must not take
place until it has been verified that the machine conforms with
directive 89/392/EEC (Machinery Directive).
It is also necessary to comply with standard EN 60204, which
stipulates in particular that electrical actuators (which include
VARMECA 14) cannot be regarded as circuit-breaking
devices and certainly not as isolating switches.
Commissioning can take place only if the requirements of the
Electromagnetic Compatibility Directive (89/336/EEC,
modified by 92/31/EEC) are met.
VARMECA 14 motors meet the requirements of the Low
Voltage Directive 73/23/EEC, modified by 93/68/EEC. The
harmonised standards of the DIN VDE 0160 series in
connection with standard VDE 0660, part 500 and EN 60146/
VDE 0558 are also applicable.
The technical characteristics and instructions concerning the
connection conditions specified on the nameplate and in the
documentation provided must be observed without fail.
3 - Transportation, storage
All instructions concerning transportation, storage and correct
handling must be observed.
The climatic conditions specified in the technical manual must
be observed.
4 - Installation
The installation and cooling of equipment must comply with
the specifications in the manual supplied with the product.
VARMECA 14 motors must be protected against excessive
stress. In particular, there must be no damage to parts and/or
modification of the clearance between components during
transportation and handling. Avoid touching the electronic
components and contact parts.
VARMECA 14 motors contain parts which are sensitive to
electrostatic stress and may be easily damaged if handled
incorrectly. Electrical components must not be exposed to
mechanical damage or destruction (risks to health!).
5 - Electrical connection
When work is performed on VARMECA 14 motors which are
powered up, national accident prevention specifications must
be respected.
The electrical installation must comply with the relevant
specifications (for example conductor cross-sections,
protection via fused circuit-breaker, connection of protective
conductor). More detailed information is given in the manual.
Instructions for an installation which meets the requirements
for electromagnetic compatibility, such as shielding, earthing,
presence of filters and correct insertion of cables and
conductors, are given in the documentation supplied with the
VARMECA 14. These instructions must be followed in all
cases, even if the VARMECA 14 carries the CE mark.
Adherence to the limits given in the EMC legislation is the
responsibility of the manufacturer of the installation or the
machine.
6 - Operation
Installations incorporating VARMECA 14 motors must be
fitted with additional protection and monitoring devices as laid
down in the current relevant safety regulations: law on
technical equipment, accident prevention regulations, etc.
Modification of VARMECA 14 motors using control software
is permitted.
Active parts of the device and live power connections must
not be touched immediately after the VARMECA 14 is
powered down, as the capacitors may still be charged. In view
of this, the warnings fixed to VARMECA 14 motors must be
observed.
During operation, all protection devices must remain fixed in
place.
7 - Servicing and maintenance
Refer to the manufacturer’s documentation.

CONNECTIONS
LEROY-SOMER
Ref. 3415 - 4.33/c - 01.02
3 - CONNECTIONS
• The voltages on the power terminal blocks and
the cables connected to them may cause fatal
electric shocks. The drive stop function does not protect
against these high voltages.
• The drive contains capacitors which remain
charged at a fatal voltage even after the power supply has
been switched off.
• After the drive has been switched off, wait for 2
minutes (so that the internal circuits discharge the
capacitors) before removing the protective covers.
• The drive power supply must be protected
against overloads and short-circuits.
• It is vital to respect the rating of protection
devices.
3.1 - Wiring precautions
- When the VARMECA 14 is controlled remotely, avoid
parallel routing of power cables and control cables.
- All remote control cables must be shielded and have a
cross-section between 0.22 mm
2
and 1 mm
2
. The shielding
should be connected at both ends.
-Checkthatthedifferentearth points are actually at the same
voltage.
- Incorporate a bend where the cables enter the cable glands
so that water cannot penetrate the terminal box.
- Tighten the cable glands firmly.
3.2 - Connectors
3.2.1 - Mounting
•Standard: Connection is made on a block with 8 terminals,
3 for the power supply and 2 for the fault relay (3 terminals are
reserved for internal LEROY-SOMER use).
3.2.2 - Connecting the mains supply
3.2.3 - Connecting the control
This is located on the side printed circuit and used for remote

•All connections and work must be carried out with
the power switched off.
When connecting a 10 kΩpotentiometer for remote control,
use the "without control knob" option. Nevertheless, for the
standard version "with control knob", a potentiometer can be
used for remote control by setting the mini-DIP switch K4 to
ON.
3.3 - Electrical and electromagnetic
phenomena
Radio-frequency interference: emission
3.3.1 - General
Variable speed drives use high-speed switches (transistors,
semiconductors) which switch high voltages (around 550 V
for 3-phase drives) at high frequencies (several kHz). This
provides better efficiency and a low level of motor noise.
Hence, they generate radio-frequency signals which may
disturbtheoperation ofotherdevices or measurementstaken
by sensors:
- due to high frequency leakage currents which escape to
earth via the stray capacity of the drive/motor cable and that
of the motor via the metal structures which support the motor
- by conduction or feedback of RF signals on the power
supply cable: conducted emissions
- by direct radiation near to the mains supply power cable or
the drive/motor cable: radiated emissions
These phenomena are of direct interest to the user.
The frequency range concerned (radio-frequency) does not
affect the energy distribution company.
3.3.2 - Standards
The maximum emission level is set by the generic industrial
(EN 50081-2) and domestic (EN 50081-1) standards.
The VARMECA 14 equipped with an FLT VMA 14 filter
conforms to the EN 50081-2 standard.
