Brake motors are assemblies made of an asynchronous motor and a failsafe braking system (safety Brake ).This Brake motor benefits from the experience of a global manufacturer, using cutting edge technologies - automation, selected materials, thorough quality control - in our motor plants who have been awarded the ISO 9001 - Issue 2008 international symbols appear in this document whenever it is important to take special precautions during installation, operation, maintenance or servicing of the Brake is prohibited to drive the extension shaft and the fan in manual rotation with the parking Brake applied, or the Brake released under load.

2 General danger Electrical hazard Risk of physical injury Risk of severe or lethal injury Risk of severe or lethal 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.

3 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 qualified, experienced and authorized personnel. The safety of people, animals and property must be ensured when fitting 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.

4 If a Brake motor is started up without a coupling device having been fitted, 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. 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 fitted with an active Brake release lock off system (DLM), it is vital to ensure safety (of people and property) in exposed any intervention on the Brake , check that it holds no an operating period, certain parts of the Brake motor may be hot and are likely to cause FFB Brake motors Maintenance Guide5287 en - / cLeroy-Somer reserves the right to modify the characteristics of its products at any time in order to incorporate the latest technological developments.
