3-phase asynchronous TEFV brake motors

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.)

PREFACE: ATEX TRAINING

Specic ATEX marking

0080 : INERIS identication number (Notied Organisation) T (max) : Maximum surface temperature: 125°C for example

: Specic marking Db, Dc : Protection level of equipment
II 2D Ex tb IIIC : Group II, category 2, Dust or: Attestation n° : Type test attestation n° issued by INERIS

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,
