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 motor must be connected to an approved earth
(B 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 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.
VARMECA is a component designed to be integrated in an installation or an electrical
machine and can under no circumstances be considered to be a safety device. It is the
responsibility of the manufacturer of the machine, the designer of the installation or the user
to take all necessary precautions to ensure that the system complies with current standards
and to provide devices to ensure the safety of equipment and personnel.
For safety reasons, LEROY-SOMER prohibits the use of VARMECA for lifting 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, 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 motors may contain moving
parts, as well as hot surfaces, during
operation.
Unjustified removal of protections, 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, installa-
tion, commissioning and maintenance
must be performed by experienced quali-
fied personnel (see IEC 364 or 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 motors are components
designed for integration in installations or
electrical machines.
When integrated in a machine, commiss-
ioning 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) 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 (EEC/89/336,
modified by EEC 92/31) are met.
VARMECA 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.
SAFETY AND OPERATING INSTRUCTIONS FOR ELECTRICAL
ACTUATORS (In accordance with the low voltage directive 73/23/EEC
modified by 93/68/EEC)

4 - Installation
The installation and cooling of equipment
must comply with the specifications in the
manual supplied with the product.
VARMECA motors must be protected
against excessive stress. In particular, the-
re 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 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
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 protec-
tive conductor). More detailed information
is given in the manual.
Instructions for an installation which meets
the requirements for electromagnetic
compatibility, such as screening, earthing,
presence of filters and correct insertion of
cables and conductors, are given in the
documentation supplied with the VARMECA.
These instructions must be followed in all
cases, even if the VARMECA 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 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
motors using control software is permitted.
Active parts of the device and live power
connections must not be touched
immediately after the VARMECA is
powered down, as the capacitors may still be
charged. In view of this, the warnings fixed
to VARMECA motors must be observed.
During operation, all doors and protective
devices must remain closed.
7 - Service and maintenance
Refer to the manufacturer's documenta-
tion.

3 - CONNECTIONS
• The voltages existing on the power
supply terminal blocks and the
connected cables may cause fatal
electric shocks. The stop function of
the controller does not protect against
these high voltages.
• The controller contains capacitors
which remain charged at a fatal voltage
level even after the power supply has
been cut off.
• After the controller power
supply has been cut off, wait for 2
minutes (so the internal circuits can
discharge the capacitors) before
removing the protective covers.
• The speed controller power
supply must be protected against over-
loads and short-circuits.
It is vital to respect the rating of
protections.
3.1 - Wiring precautions
- When the VARMECA is controlled
remotely, avoid parallel routing of power
cables and control cables.
- All remote control cables should be
shielded and have a cross-section
between 0.22 mm2 and 1 mm2.
- Incorporate a bend where the cables
enter the cable glands so that water cannot
penetrate the terminal box.
- Tighten the cable glands firmly.

necessary to undo these connections.
3.2.4 - Control terminal block
This is located on the side printed circuit
and is used for remote control.
To open blade terminals use a flat screw-
driver with a maximum width of 2.5 mm.
On leaving the factory, terminals 5 and 6
are connected together (ramp 5s) as well
as terminals 6 and 8 (forward).
3.2.5 - Fault relay terminal block
3.2.6 - Connection
All connections and work must
be carried out with the power
switched off.
✶✶ Connection of a 10kΩpotentiometer for
remote control should be carried out with the
"without control button" option. Nevertheless,
if you have the standard "with control button"
version, it is necessary to remove connection
S1 (located on the side printed circuit which
holds the terminal block) with a soldering
iron, to avoid parallel connection of both
potentiometers.

6 - MAINTENANCE
• All work related to installation,
commissioning and maintenance
must be carried out by experienced and
qualified personnel.
• Do not carry out any work
before the VARMECA power supply has
been cut off and locked, and wait 2
minutes until the capacitors have
discharged.
6.1 - Servicing
No specific maintenance is required for
VARMECA motors, apart from the
regular removal of dust from the
ventilation louvres and the cooling
fins situated at the bottom of the box.
Do not dismantle the VARMECA while it
is still under guarantee, as this would
then immediatelybecome null and void.
CAUTION :
The rear cover protects the electronic
boards and should only be removed for
adjustment using the mini DIP switch
marked S4 ✶.
Certain components which are sensitive
to electrostatic discharges can be
destroyed simply by touching them.
Do not leave any metal object in the
connection area, as this might cause a
short-circuit.
✶ For ratings 300 and 400, S4 can be
accessed without removing the rear cover,
via the connection space, through a
special opening in the rear cover, which is
protected by a plastic plug.
6.2 - Measurements
6.2.1 - General
The input voltages can be measured with
ordinary instruments.
Motor current is not measured on the
VARMECA power supply (L1, L2, L3). It
is measured with an ordinary clamp ammeter
on the longest wire, which forms a loop on
the side of the connection circuit.
6.2.2 - Procedure for measuring the
motor current (if the motor wire loop is
accessible)
- Open the VARMECA power supply
circuit and lock it.
- Wait 2 min for the capacitors to discharge.
- Open the cover of the VARMECA.
- Remove the mains cable (L1, L2, L3).

7.1 - Option without control button
(SD or SG)
The potentiometer is no longer located on
the VARMECA (the indicator lamp remains),
but near the operator.
Ramp selection and selection of running
direction can also be positioned close to
the operator.
7 - OPERATING EXTENSIONS
7.2 - Integrated run-stop control option (CMA)
With a Run key and a Stop key located on the cover, it is possible to control the VARMECA
locally, as desired, once powered up.
7.3 - Forward/Reverse/Stop control option (CMAVAR)
As with the CMA option, the keys are located on the cover. They are used to control the
motor locally in both directions of rotation.
For an instruction to be taken into account, the relevant key must be held down for 1 second.

7.4 - Grouped options (RDCVS)
The RDCVS printed circuit is fitted instead
of the standard connection circuit and
offers the additional functions described
below.
7.4.3 - Selector switches for the speed
reference
The selection is made according to the table
below :
Factory setting.
7.4.1 - Speed controller fault
Volt-free contact (1A/250V) on terminal block
no. 4 (terminals P1 - P2). Contact open when
there is a fault on the electrical part or when
the speed controller is switched off.

7.4.2 - Adjustment of the internal speed (VIT INT) and the maximum speed (VIT MAX) via
potentiometers.
The "VIT MAX" potentiometer is used to reduce the maximum speed for a maximum
reference, independently of the setting of S4. The "VIT INT" potentiometer is used to adjust an
operating speed : it replaces the adjustment of the external potentiometer. Access to these
settings depends on the position of the selector switches (S1, S2, S3).

7.5 - EMC filter option (FLT VMA)
The filter is located in the VARMECA
cover and is connected instead of connec-
tions 1-4, 2-5, 3-6, paying attention to the
colour of the wires.
It is essential to connect the filter PE terminal.
7.6 - Electromechanical brake option
The motor should be equipped with an
FCR brake adapted for the VARMECA.
The brake has an integral power supply.
The brake is energised as soon as the
run instruction has been validated. It is
released after a stop instruction, at the
end of deceleration or on disconnection of
the power supply.
The rectifier circuit is mounted on the
motor terminal plate.
