GENERAL WARNING
This document complements general manual ref. 1889 (recommendations), ref. 4850 (LSES motor), ref. 4155
(LSRPM motor) and guide FFB brake maintenance ref. 5287. All documents are downloadable : www.leroy-somer.com
FFB brake motors are units consisting of an induction motor and a failsafe braking system (safety brake).
This brake motor benets from the experience of one of the largest manufacturers in the world, using state-of-the-art technology in
automation, specially selected materials and rigorous quality control. As a result, the regulatory authorities have awarded our motor
factories the ISO 9001 - Edition 2008 international certicate.
These symbols appear in this document whenever it is important to take special precautions during installation, operation,
maintenance or servicing of the brake motors.
It is prohibited to drive the extension in manual rotation and the fan with the parking brake applied, or the
brake released under load.
General danger Electrical hazard Mechanical hazard
risk of serious or mortal injury risk of serious or mortal injury
These recommendations, instructions and descriptions refer to standard use. They do not take account of non-standard
versions or special adaptations. Failure to comply with these recommendations can lead to premature wear and tear of the
motor and can invalidate the manufacturer warranty.
Make sure that the brake motor is compatible with its environment before its installation and also throughout its life.
The following preliminary precautions must be taken before working on any stationary device:
• Mains voltage disconnected and no residual voltage present
• Careful examination of the causes of the stoppage (blocked transmission - loss of phase - cut-out due to thermal
protection - lack of lubrication, etc.)
Electric brake motors are industrial products. They must therefore be installed by qualied, experienced and authorized
personnel. The safety of people, animals and property must be ensured when tting the motors into machines (please refer
to current standards).
Particular attention must be given to equipotential ground or earthing connections.
Safety of personnel: Protect all rotating devices before power-up. If a brake motor is started up without a coupling device
having been tted, carefully immobilize the key in its location. All measures must be taken to ensure protection against the
risks which arise when there are rotating parts (coupling sleeve, pulley, belt, fan, etc.). Personal protective equipment must
be worn. In the case of a brake motor delivered without a hood and without a fan, there is a burning and cutting risk.
After work is carried out, the lids of the terminal box and its cover must always be closed.
Beware of backdriving
When the brake motor is tted with an active brake release lock off system (DLM), it is vital to ensure safety (of people
and property) in exposed areas.
Before any intervention on the brake, check that it holds no load.
- After an operating period, certain parts of the brake motor may be hot and are likely to cause burns.

1.2 - Storage
Store the equipment in a clean, dry location, protected
from shocks, vibrations, variations in temperature and in an
environment with relative humidity of less than 90%.
Storage for longer than 6 months leads to special conditions,
we will be happy to discuss these with you.
After storage for a period of more than 6 months, disconnect
the brake power supply unit and check the winding insulation
resistance (phase/earth resistance higher than 10 MΩ). Drain
any condensation water.
2 - RECOMMENDATIONS
2.1 - Commissioning
The brake motor is designed to operate at the speeds indicated
on the nameplate (do not exceed the maximum speeds stated
in our technical catalogues).
Comply with the voltages and frequencies indicated on the
nameplate (do not deviate by more than 5% from the voltage
extremes on the nameplate and by more than 1% from the
frequencies).
For hoisting applications, do not use a motor that is not rated
S3 (except for variable speed). Do not use a motor with a
different duty type from that on the nameplate no. ➈.
2.2 - Mechanical installation
(Also see manual 1889)
If the brake motor has been stored at a temperature lower
than -10°C, heat it and turn the shaft manually before starting
up the machine.
If the brake motor is to be used at a temperature lower than
-25°C, it must not be tted with a sensor. It can be tted with
thermocouples.
Ensure there is minimum clearance (corresponding to
the length of the cover) at the non-drive end of the brake
motor so it can be put down (inspections and brake
adjustments).
Install the brake motor in conditions conforming to those on
the order (temperature, relative humidity, altitude).
When the brake motor is tted with lifting rings, these are
for lifting the brake motor on its own (tighten the ring, if
necessary, before handling).
Mount the brake motor in the position specied on the order,
on a at, rigid base in order to prevent distortion and vibration.
Make sure that the holding screws are tightened to the correct
torque according to NF E25-030-1. (class 8.8 minimum
according to ISO 898-1), the screw diameter must be the right
size for the xing holes.
Ensure the mechanical shafts are aligned and the
transmission mechanism is mounted in accordance with good
practice.
Ensure the mass continuity; no modications to the brake
motor are authorised.

RECOMMENDATIONS
Installation guide FFB brake motors
5286 en - 2017.09 / c
en
Do not knock the motor (terminal box, cover), the shaft or
the coupling during mounting, do not crush the seal, do not
project beyond the shoulder of the shaft.
Ensure correct brake motor cooling, the air intakes and outlets
must be kept clear.
Check that the loads applied to the motor shaft (especially
the belt tension) are compatible with the values stated in our
technical catalogues.
2.2.1 - Brake with options
It is prohibited to drive the extension in
manual rotation and the fan with the
parking brake applied, or the brake
released under load.
- Auto-return hand brake release (DLRA)
For brakes tted with a lever, push it towards the back of the
brake motor.
Whenever the brake has been released, make sure that
it is engaged once any maintenance operations have been
completed.
See dismantling/reassembly procedure in ref.5287 FFB
maintenance.
- (Manual) brake release lock off system (DLM)
For brakes tted with a DLM, proceed in the same way as the
DLRA to release the brake and then turn (clockwise) the DLM
handle in line with the DLRA to lock the brake in the released
position. When the brake is next powered up, it is engaged
automatically and the brake is operational again.
See dismantling/reassembly procedure in ref.5287 FFB
maintenance.
- Remote (electrical) brake release lock off (DMD)
For brakes tted with a DMD, supply the brake coil with
power separately from the motor. Once the brake is released,
supply the electromagnet on the lock control board with
power. Once the locking contactor is engaged, switch off the
brake coil power supply and then that of the control board.
The brake is held in the released position. When the brake is
next powered up, it is engaged automatically and the brake is
operational again.
Whenever the brake has been released, make
sure that it is engaged.
- Release indicator (open/close)
For brakes tted with a release indicator, while the brake is
supplied with power the armature actuates a microswitch
(discrete) xed on the backplate indicating brake release.
When the power is switched off, the microswitch changes
state in order to conrm that the brake is engaged.
- Wear indicator
For brakes tted with a wear indicator, while the brake is
supplied with power the armature actuates a microswitch
(discrete) xed on the yoke. If the brake lining is worn
(+ 0.6 mm) the microswitch is actuated and informs the user
of the need to adjust the air gap or change the brake lining if it
is less than the required minimum (See the “Adjusting the air
gap” procedure in ref.5287 FFB maintenance).
2.3 - Electrical connection
The cables should be connected with the power
off by qualied personnel, in accordance with
good practice, in compliance with the safety
conditions. Choose the protection system and
cables according to the information on the
nameplate (the voltage drop during the starting
phase must be less than 3%).
Tighten the terminal lock nuts, connectors and power supply
cables to the torque stated below (N.m):
Terminal
M4 M5 M6 M8
Steel 1 2.5 4 10
If using cables without connectors, attach calipers.
- Do not place washers or lock nuts between the motor
connections and the connections on the power supply cable.
Connect the thermal protection devices and accessories
(section 3.5).
Ensure that the cable gland is watertight (the cable gland
must always correspond to the diameter of the cable used).
Incorporate a bend where the cable enters the terminal box
to prevent water entering via the cable gland.
Check the motor direction of rotation (section 3.1).
The internal terminal box connections must never be put
under any stress due to the cables connected by the user.
Earthing
It is mandatory to earth the brake motor (in the terminal
box and on the brake), and earthing must be performed in
accordance with current regulations (protection of workers).
Power supply (see wiring diagrams under the terminal box
cover, section 3).
Brake motors with a built-in power supply are connected like
standard motors. They are tted with a DC coil (180 VDC).
The brake is supplied directly from the motor stator
(230/380/400/415/460/480 V) via a brake power supply unit,
rectier mounted in the terminal box.
For motors with different voltages, starting at reduced
voltage or operating at variable voltage or frequency, a
separate brake power supply must be provided. (The same
applies to a 20 VDC coil).
To reduce the brake application response time (mandatory
in Hoisting applications), it is necessary to switch off the
brake DC power supply at the same time as that of the
motor, usually via an auxiliary contact on the motor starting
contactor.

The terminal box is watertight once the cable glands have been
tted and each cable gland is tightened on the cable according
to its cable size.
Adapt the cable gland and its reducer if present to the diameter
of the cable being used.
In order to maintain the brake motor's original IP55 protection,
it is essential to ensure the cable gland provides a total seal by
tightening it correctly (so that it cannot be unscrewed by hand).
When there are several cable glands and some are not being
used, ensure that they are always covered (threaded plugs)
and tighten them so that they also cannot be unscrewed by
hand.

- For reasons of synchronization, power up and power
down the encoders and any associated electronic devices
simultaneously. On the rst power-up, check that the
“supply +” terminal is supplying the required voltage before
connection.
- For the supply, use stabilized power supplies.

Checks after start-up
After approximately 50 hours’ operation, check that the screws
xing the motor and the coupling device are still tight. In the
case of chain or belt transmission, check that the tension is
correctly adjusted. Check the electrical connections. Check the
vibrations. Check that there is no abnormal noise. If the brake
wear needs to be checked: measure that the clearance is lower
than the max dimension authorised. (see the “Adjusting the air
gap” procedure in section 4.4 ref. 5287 FFB maintenance)
Preventive maintenance visit
- Check regularly that the recommendations concerning
mechanical and electrical installation are still complied with.
- Inspect the seals.
- Remove any dust or foreign bodies which might clog the
cover grille and the housing ns.
- Lubricate the bearings of the motors tted with grease
nipples.
Cleaning
Precautions to be taken: before carrying out any cleaning
operation, check that the brake motor is totally sealed
(terminal box, drain holes, etc).
Dry cleaning (vacuuming or compressed air) is always
preferable to wet cleaning.
To ensure the brake motor operates correctly, remove any
dust or foreign bodies that might clog the brake moving
parts, the cover grille and the housing ns.
Always clean at reduced pressure from the
center of the brake motor outwards to avoid
introducing dust and particles under the seals.
Draining condensation water
Temperature variations cause condensation to form inside the
motor, which must be removed before it adversely affects
motor operation.
Condensation drain holes, located at the bottom of the motors
(bearing in mind their operating position) are sealed with plugs
that must be removed and then replaced every six months (if
they were not replaced, the motor degree of protection would
no longer be maintained). Clean the orices and plugs before
reassembling them.
Note: In conditions of high humidity and signicant temperature
variations, a shorter period is recommended.
When there is no risk to the motor protection, the condensation
drain plugs can be removed.

Special marking (EXAT) ➉ (§1.1):
FFB250NU001
Mf :
52 Nm
S N° : 9999999/001
U : 180 VDC I : 345 mA
Motor size : 168
Nmax : 3600 rpm
II 3 D Ex tc IIIB T125°C Dc

6.5 kg
II 3D Ex tc IIIB: Group II, category 3, non-
conductive dusts.
T125°C : température maximale de surface.
Dc: equipment protection level.
Nmax 3600 rpm : maximum rotation speed in
Exat.
The brake must be assembled with a motor which respects
the same EXAT level requirements at least.
If the brake is not equipped with a release/application
indicator, check the clearance periodically according to
the rates and the energy to be dissipated on each braking
operation (see technical catalogue ref 5329 § Operation).
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 open when powered up in atmospheres
D21containing explosive dust,
- do not repair when powered up,
- do not manoeuvre when on load,
- wait several minutes before opening,
- replace the seals tightly to ensure watertightness.
