8. Safety
The brakes described in these Operating Instructions have been designed and built on the basis of an
analysis of hazards and in accordance with the requirements of the applicable harmonised standards and
technical specifications. They correspond to the state of the art and provide maximum safety. However,
safety hazards can only be avoided if the user of the equipment takes adequate precautions and makes sure
that the safety instructions are strictly adhered to.
The user is required to ensure that:
•
the brakes are only used in accordance with their intended use (see Section 2 "Product description").
•
the brakes are in perfect working order and checked at regular intervals.
•
a complete and fully legible copy of these Operating Instructions is kept available at the place of use of
the brakes at all times.
•
start-up, maintenance and repair work is only done by authorised and suitably qualified personnel.
•
such personnel are kept informed on all relevant occupational safety and environmental protection
issues and familiar with these Operating Instructions and with the safety information contained herein.
•
the brakes are not exposed to other strong magnetic fields.
8.1 Intended
use
The brakes described in these Operating Instructions are intended to be assembled with machines, in
particular electric motors, for use on industrial plant and, more specifically, in atmospheres susceptible to
firedamp. The brakes must be used in accordance with the operating requirements detailed in this manual.
The rated power limits specified herein must not be exceeded.
8.2 General
safety
information
Brakes fitted to motors feature hazardous live components and rotating parts and may exhibit hot surfaces.
Any work associated with the transport, connection, start-up and periodical maintenance of the brakes must
be carried out by authorised and suitably qualified personnel (in accordance with VDE 0105; IEC 364).
Failure to observe safety, operating and maintenance instructions may cause serious personal injury and
severe damage to the equipment. Whenever special measures are required in accordance with the
instructions contained herein, such measures should be agreed with the brake manufacturer before the
machinery into which the brake is to be incorporated is set up. Should any queries arise with respect to
torques, torque variations, installation positions, wear, wear reserve, switching work, break-in conditions,
release range, ambient conditions and the like, please contact Kendrion Binder and ask for clarification
before using the brake. Retrofitting or modification work to be carried out on the brake is subject to the
approval from Kendrion Binder. Accident prevention regulations applying to the specific field of application of
the brake must be strictly observed. The brakes described in this manual are
not
designed for use as
"safety brakes"
. This means that torque reductions caused by factors beyond the user's control cannot be
excluded.
8.2.1 Set-up
Requirements in terms of the permitted number of switching operations per hour and the maximum switching
work per switching operation (see Fig. 29/1) specified in the technical specifications must be strictly observed
during the set-up of machines and plant (inching mode). Failure to observe these instructions may
irreversibly diminish the braking effect and cause malfunctions. The operating conditions at normal rating
specified in these Operating Instructions refer to DIN VDE 0580. The protection type is based on EN 60529.
In case of deviations from these requirements, special precautions may have to be taken after consultation
with the brake manufacturer. If vertical brake operation is envisaged, any special requirements must be
agreed with the manufacturer. Bear in mind that the friction disc may freeze if ambient temperatures fall
below -5°C or if the brake remains unpowered for prolonged periods of time. In this case, special precautions
must be taken after consultation with the manufacturer.
