NOTE
LEROY-SOMER reserves the right to modify the specifications of its products at any time in order to incorporate the
latest technological developments. The information enclosed in the present document may therefore change without notice.
LEROY-SOMER gives no contractrual guarantee whatsoever concerning the information published in this document and
cannot be liable for any error it may contain nor for any damage arising from its use.
CAUTION
For the own safety of the user, this speed controller must be connected to an approved earth (terminal B).
If an accidental start of the installation represents a risk for personnel or the machines to be driven, it is imperative that the
power supply of the drive is fitted with an isolating switch and a circuit-breaking device (power contactor) controllable through an
external safety system (emergency stop, fault detector).
The speed controller is fitted with safety devices which can stop the controller in the event of faults and thus stop the motor. The
motor itself can be jammed for mechanical reasons. Finally, voltage fluctuations, and particularly power cuts, can also cause the
motor to switch off.
The cure 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 makes appropriate arrangements against restarting after unscheduled stops of the
motor.
The speed controller is designed to be able to power a motor and the driven machine above its rated speed.
If the motor or the driven machine is not mechanically designed to operate at such speeds, the user risks serious injury
from the resulting mechanical damage.
Before programming a high speed, it is essential that the user ensures that the system can withstand it.
The speed controller is a component designed for integration within an installation or an electrical machine : it is therefore of the
responsibility of the user to make sure the system complies with current standards.
LEROY-SOMER declines all responsibility whatsoever should the above recommendations not being complied with.
........................................
Manual corresponding to software version 1.1.1
For more recent software versions, refer to enclosed appendix or ask LEROY-SOMER

Throughout the manual, this symbol warns
against consequences which may arise from
inappropriate use of the speed controller, since
electrical risks may lead to material or physical
damage as well as constitute a fire hazard.
1 - General
According to their degree of protection, speed controllers
can during operation comprise bare live parts,
sometimes moving or rotating, as well as hot surfaces.
Unjustified removal of protections, incorrect use, faulty
installation or inappropriate operation could represent a
serious risk to personnel and machinery. Refer to the
manual for additional information.
Any work related to transportation, installation,
commissioning and maintenance must be carried out by
experienced and qualified personnel (see CEI 364 or
CENELEC HD 384, or DIN VDE 0100 and national
specifications for installation and accident prevention).
According to these basic safety instructions, qualified
personnel means persons competent to install, mount,
commission and operate the concerned product and
possessing the relevant qualifications.
2 - Use
Speed controllers are components designed for
integration within an installation or an electrical machine.
When integrated in a machine, commissioning is
forbidden as long as conformity with Directive
89/392/CEE (Machinery Directive) has not been
checked. It is also necessary to comply with standard EN
60204, which especially stipulates that electrical
actuators (which include speed controllers) cannot be
regarded as circuit-breaking devices and by no means
as isolating switches.
Commissioning can take place only if the requirements
of the Electromagnetic Compatibility Directive
(89/336/CEE, modified by 92/31/CEE) are fulfilled.
Speed controllers fulfil the requirements of the Low
Voltage Directive 73/23/CEE, modified by 93/68/CEE.
The harmonized standards of the DIN VDE 0160 series
in connection with standard VDE 0660, part 500 and EN
60146/VDE 0558 are also applicable.
Technical specifications and instructions concerning
connection conditions specified on the rating plate and in
the supplied documentation must absolutely be
respected without fail.
3 - Transportation, storage
All instructions concerning transportation, storage and
correct handling must be respected.
Climatic conditions specified in the technical manual
must be respected.
4 - Installation
Installation and cooling of equipment must comply with
the specifications stated in the manual supplied wit the
product.
Speed controllers must be protected against excessive
stress. More particularly, avoid any damage to parts
and/or modification of insulation distances between
components during transportation and handling. Avoid
touching electronic components and contact parts.
Speed controllers include parts which are sensitive to
electrostatic stress and can easily be damaged if
handled incorrectly. Electrical components must not be
exposed to mechanical damage or destruction (possible
risks to health !).
5 - Electrical connection
When work is carried out on the powered-up speed
controller, national specifications for accident prevention
must be respected.
Electrical installation must conform with the appropriate
specifications (for instance wire section, protection with
circuit-breaking fuse, connection of protective
conductor). Refer to the documentation for more detailed
information.
Instructions for an installation complying with
electromagnetic compatibility requirements (such as
screening, earthing, presence of filters and correct
mounting of cables and conductors) are outlined in the
documentation supplied with the speed controller. These
instructions must always be respected even if the speed
controller has the CE mark. The manufacturer of the
installation or of the machine is responsible for the
conformity with the limits given in the EMC legislation.
6 - Operation
Installations incorporating speed controllers must be
fitted with additional protection and monitoring
equipments specified in the current relevant safety
regulations, such as law on electrical equipment,
specifications for accident prevention, etc…
Modifications to speed controllers using control software
are allowed.
After the speed controller has been powered down,
active parts of the equipment and live power connections
must not be touched immediately as the capacitors may
still be charged. In view of this, refer to the warnings
marked on the speed controllers.
During operation, all doors and protections must remain
closed.
7 - Service and maintenance
Refer to the manufacturer's documentation.
This document must be passed on to the end user.

664.1). The controller must not be installed in a
hazardous area unless it is enclosed in a specially
adapted cubicle. In this case the installation must be
certified.
• Within atmospheres subject to condensa-
tion, it is necessary to install a heating system which
functions when the controller is not in use and is
disconnected when the controller is operating.
Ideally this heating system should be controlled au-
tomatically.
• The housing of the UMV 2301 AS controller
is not fireproof : therefore it might be necessary to
use a fireproof cubicle.
• The UMV 2301 AS rating more than 22T
weigh more than 22 kg. They should be handled
using adapted means.
2.1 - Checks on receipt
Before installing the controller, make sure that :
- the controller has not been damaged during transport,
- all mounting accessories are included,
- the nameplate is corresponding to the power supply
and motor specifications.
2.2 - Installation precautions
The controller should be mounted upright with a
clearance of 100 mm over and under.
Do not mount the UMV 4301 controller over a heat
source or another controller. There is a risk for
tripping when the radiator temperature reaches 90°C.
Never obstruct the ventilation louvres.
The UMV 2301 AS 60T to 120T controllers are
supplied with 2 M10 tapped holes for fitting
shackles.
2.3 - Installation of the controller
2.3.1 - General
There are 2 differents ways to install the controller :
heat sink inside or outside of cubicle. With the latter
configuration it is not necessary to dissipate the
controller losses.

2.3.2 - Mounting with heat sink inside the cubicle
The UMV 2301 AS 8T to 16T controllers must absolutely be mounted on a massive base plate in order to direct the
cooling air flow efficiently : otherwise, 20 % derating is necessary.
The UMV 2301 AS controllers 22T to 120T can also be mounted on a grille, a frame or a DIN rail support.
- Insert the mounting lugs into the grooves on top and under the heat sink,
- Fasten the lugs onto the base plate, the DIN rail support or the grille with M6 screws.

14
4 - Set on the frame the gasket suplied with the
controller.
5 - Insert the controller in the cut-out of the rear panel.
6 - Fasten the controller through the upper mountings
and the lower holes.
WARNING :
Make sure that the air flow beyond the cubicle is
sufficient.
2.3.3 - Mounting with heat sink outside of cubicle
1 - Cut out and drill the rear panel of the cubicle.
2 - Insert a mounting lug into the groove on top of
controller.
3 - For the UMV 2301 AS controllers rating 22T to 50T
and 60T to 120T, remove the lower terminal block cover
in order to get access to the mounting holes.

3 - CONNECTIONS
• All connection works must be carried out
according to the current legislation of the
concerned country. This includes earthing or
grounding in order to make sure that no directly
accessible part of the controller can remain at mains
potential or any other voltage that may be
hazardous.
• The voltages existing on the wires or
connections to the mains, the motor, the braking
resistor or the filter, may cause fatal electric shocks.
Avoid contact in any case.
• The controller must be supplied through a
circuit-breaking device in order to disconnect it
safely.• The controller power supply must be
protected against overloads and short-circuits.
• The stop function of the controller does not
protect against the high voltages existing on the
terminal blocks.
• The controller contains capacitors which
remain charged at a fatal voltage even after the
power supply has been cut off.
• After the power supply has been cut off, wait
for 10mn before removing protective cover.
• Make sure that voltage of DC bus is lower
than 40V before any work is carried out.
• Check that voltage and current of controller,
motor and mains are compatible.
3.1 - Connection of induction motor
3.1.1 - Terminal block
The LS MV motors are mainly dual-voltage motors,
230/400V. As standard, star-connection should thus be
used.
Nevertheless, check the nameplate before connecting
the motor.
3.1.2 - Auxiliary terminal blocks
3.1.2.1 - Optionel forced ventilation
LS MV motors can be fitted with an optional forced
ventilation as follows :
• Motor LS MV with frame size ≤132, single-phase
power supply as standard :
• Motor LS MV with frame size ≥160
