Operating Instructions BA 77 600..A00 // Last updated: 13/03/2020 // Page 24 of 33 

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. Operation in potentially explosive atmospheres or 

locations requiring flame-proofing is not allowed. 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 specialist personnel in accordance with EN 50110-1, 

EN 50110-2, IEC 60364-1. 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 (Villingen) 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 (Villingen). 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.
