This document complements the general instructions ref. 1889 (recommendations), ref. 3770 (LS), ref. 4850 (LSES LS2/IE2),
ref. 3255, 3385 (ATEX specic recommendations) and the specic instructions ref. 2908 (FCR brake motor installation).
FCR brake motors are monobloc units consisting of an induction motor and a failsafe brake system (safety brake).
This motor benets from the experience of one of the largest manufacturers in the world, using state-of-theart technology in automation, specially
selected materials, rigorous quality control. As a result, the regulatory authorities have awarded our motor factories the ISO 9001 - Edition 2008
international certicate.
EC conformity: motors conform to the harmonized standard EN 60034 (IEC 34) therefore with the low voltage Directive 2006/95/EC and as EC
marked.
The noise level of the machines, measured under normal conditions, conforms to the requirements of the standard (IEC 34-9).
IMPORTANT
These symbols appear in this document whenever it is important to take special precautions during installation, operation,
servicing or maintenance of the motors.
The specications, instructions and descriptions are for standard operation. They do not take account of structural variants or
special adaptations. Failure to comply with these recommendations may lead to premature deterioration of the motor and voiding of the
manufacturer’s guarantee.
Check motor compatibility with its environment before installation and over its entire operating lifetime.
Electric brake motors are industrial products. Therefore, they must only be installed by qualied experienced and authorised
personnel. The safety of people, animals and goods should be ensured when tting the motors into machines (please refer to current
standards).
Particular attention should be given to the equipotential ground or earthing connections.
Workforce safety: protect all rotating devices before power-up. If running a motor without tting a coupling device, carefully immobilise the key in its
location. All measures must be taken to ensure protection from the risks presented by rotating parts (sleeve, pulley, belt, etc.). Beware of backdriving
when the motor is switched off, it is necessary to take appropriate precautions: pumps, install a non-return valve, for example.
The following precautions must be taken before working on any stopped device:
• mains voltage disconnected and no residual voltage present
• careful study of the causes of the stoppage (blocked transmission - loss of phase - cut-out due to thermal protection - lack of lubrication,
etc.)

Those persons required to work on electrical installations and equipment in zones where there is a risk of explosion must be specially trained in the
necessary skills.
In effect, they must be familiar not only with the electrical risks, but also with those that are due to the chemical properties and physical characteristics
of products used in the installation (gas, vapour, dust), as well as the environment in which the equipment operates. These elements dictate the risk
of re and explosion.
In particular, they must be informed and aware of the specic safety reasons and requirements in order to adhere to them.
For example:
- do not open when powered up, - do not manoeuvre when on load,
- do not open when powered up in atmospheres - wait several minutes before opening,
containing explosive dust, - replace the seals tightly to ensure watertightness.
- do not separate when powered up,

4.6 - Special operating conditions
- Thermal protection (see 2908 § 2.6)
- Space heaters (see 2908 § 2.6)
- Temperatures: storage and ambient
Note: Ta = ambient temperature
If it has been stored at a temperature lower than -10°C, heat the motor
and turn the shaft manually before operating the machine.
If used at a temperature lower than -25°C, the motor does not require
a temperature sensor to be tted. It can be tted with thermocouples.
Our standard motors are intended to operate at an ambient temperature
between -25°C and 40°C.
- Surface temperature
As standard, the maximum surface temperature of our motors is 125°C
with a maximum ambient temperature of ≤ 40°C. Without derating the
motor, the maximum surface temperature will be:
• 135°C if 40°C ≤ Ta ≤ 50°C
• 145°C if 50°C ≤ Ta ≤ 60°C
- Contactors - isolators
In all cases, the contactors, isolators, etc. must be installed and
connected in an enclosure offering a degree of protection and surface
temperature compatible with the installation zone, or outside danger
zones (outside zones 20, 21 and 22).
- Connection
Particular attention must be paid to the nameplate so as to choose the
correct type of connection for the supply voltage.
- Bearing maintenance
When you detect on the motor:
- a noise or abnormal vibration,
- abnormal temperature rise in the bearing even though it is lubricated
correctly, the state of the bearings must be checked.
Damaged bearings must be replaced as soon as possible to
prevent worse damage to the motor and the driven equipment.
When one bearing needs to be replaced, the other bearing must also
be replaced.
The free bearing allows the rotor shaft to expand (make sure it
isidentied during dismantling).
- Seals
After removing the drain plugs, replace them in order to ensure
that the motor conforms to IP 55 or 65 protection. Replace the
removed seals with new seals of the same type. Clean the orices and
plugs before replacing.
On removal, and at least once a year, replace seals on the shaftway,
the shield spigots and the terminal box cover with new seals of the
same type, after cleaning the parts. The shaftway seals must be tted
using grease of the same type as the bearings.
4.7 - ATEX operating
- IP 65 protection for the motor
Whenever the motor is dismantled, during on-site
preventive maintenance, replace the seals for the
shaftways, shield spigots, the terminal box cover (if mastic)
with new seals of the same type, after cleaning theparts. The
shaftway seals must be reassembled using grease of the
same type as used on the bearings.
Whenever the drain plugs are removed, they must be
replaced to ensure IP 65 protection for the motor.
Replace used seals with new seals of the same type. Clean
the orices and plugs before reassembly.
After removing the terminal box cover, replace the seal
with a new seal of the same type after cleaning the
parts if its state no longer guarantees the required degree of
protection.
- Variable speed utilisation
Special precautions need to be taken when these motors are powered
by a frequency inverter or voltage controller:
The reference voltage (drive output or motor input) is
400 V at 50 Hz. The drive should deliver a constant
voltage/frequency signal to the motor.
The operating range is limited to 25 to 50 Hz for 50 Hz
supplies and for 50 Hz motors designed with natural
cooling.
The drives and probe connection devices must be
installed outside danger zones (outside zones 20, 21
and 22).
Regardless of the number of poles, the speed must
never exceed 3 600 min-1.
Motors supplied by a frequency inverter must be tted with
winding sensors and a sensor on the DE shield if
appropriate. These sensors must be connected to a motor cut-off
device placed outside the explosive zone, so that the maximum
surface temperature (indicated on the device) is never reached
(Ref. 2908 § 2.6).
Particular points:
- forced ventilation is forbidden.
- incremental encoder utilisation requires ATEX homologation
(IP 65) of the encoder.

5 - TROUBLESHOOTING GUIDE
Incident Possible cause Action
Abnormal noise Originating in motor or driven machine? Uncouple the motor from the driven equipment and
test the motor on its own
Test the brake release system
Noisy motor Mechanical cause: if the noise persists after
swit ching off the electrical power supply
- vibration - Check that the key conforms with the type of
balan cing
- damaged bearings - Change the bearings
- mechanical friction: ventilation, brake disc, coupling - Check
Electrical cause: if the noise stops after switching
off the electrical power supply
- Check the power supply at the motor terminals
- normal voltage and 3 phases balanced - Check terminal block connection and tightening of
the connectors
- abnormal voltage - Check the power supply line
- phase imbalance - Check the winding resistance and the supply
(vol tage) balancing
Motor heats up
abnormally
- faulty ventilation - Monitor the environment
- Clean the fan cover and the cooling ns
- Check the fan is correctly mounted on the shaft
- faulty supply voltage - Check
- terminal connection fault - Check
- overload - Check the current consumption against the current
shown on the motor nameplate
- partial short-circuit - Check the electrical continuity of the windings
and/or the installation
- phase imbalance - Check the windings resistance
Motor does not start no load
- mechanical locking
- broken supply line
Release the brake, and with the motor switched off:
- check the shaft rotates freely by hand
- check fuses, electrical protection, starting device,
electrical continuity
on-load
- phase imbalance
When switched off:
- check the direction of rotation (phase order)
- check the resistance and the continuity of the
win dings
- check electrical protection
The brake does not release Insufcient supply voltage:
Defective coil:
The maximum permissible voltage drop is 15 % of
the rated voltage
Change the coil
The brake releases but it is
very noisy:
Air gap irregular, or too large:
Foreign body in the air gap:
Dismantle if necessary and clean (see §4)
Clean the parts
The brake releases but
braking is insufcient
Insufcient pressure on springs:
Correct pressure on springs:
Adjust springs (see instructions §4) and
Check for wear on the linings
Check the surface condition of the ring and the brake
shield
Blow away any friction dust
