Page 8: General Safety Instructions
Introduction 1.2.1 General Safety Instructions Prior to mounting and start-up, carefully read the instruction manual, particularly observing the safety instructions and recommendations therein. Failure to comply with these instructions may result in personal injury and material damages. Furthermore, observe the state of the art as well as all applicable safety regulations and standards of the respective countries. -
Page 9: Safety Instructions For Operation
1.2.4 Permissible Friction Work When operating the brakes, adhere to the friction work values specified in the KEB catalogue "Electromagnetic Technology" taking the frequency of operation and the speed into account. Exceeding these specifications may result in thermal overload of the lining and a strong decrease in braking torque. -
Page 10: Risks Caused By Electric Power
Introduction Danger - Rotating Parts! The brake is used to decelerate rotating axes. There is a risk of body parts being caught or crushed. Depending on installation, provide safety measures against being caught or crushed! Warning! Warning - Hot Surface! The heat generated during the operation of the brake causes the surfaces to heat up! Due to the risks arising therefrom, always use appropriate personal... -

Page 14: Functional Description
Product Description Functional Description The COMBISTOP type 38 brake is an electromagnetically actuated dual-surface spring-applied brake for dry running. The braking force is generated in de-energised state by pressure springs which press the armature and the lining against the friction surfaces. The lining is twist-proof but can be axially moved while connected to the shaft. -
Page 15: Transport And Storage
Transport and Storage Transport and Storage The brake is delivered to the customer by a transport company that has been authorised by the manufacturer. Inspections on Acceptance by the Recipient The brake is delivered to the customer in a cardboard packaging. On arrival at the customer's premises, the brake needs to be checked for visible transport damages. -

Page 17: Mounting The Brake
Mounting and Start-up – The angular deviation of the mounting surface relative to the shaft must not exceed the following values: Size 02 to 03: 0.04 mm; Size 04 to 05: 0.05 mm; Size 06 to 07: 0.06 mm; Size 08 to 10: 0.08 mm; Size 11: 0.1 mm (in relation to the mounting hole diameter). - Page 18 Mounting and Start-up Make sure that the hub cannot run against the second friction surface. Taking into account the axial play of the shaft, a distance of 0.5 mm to 1 mm is recommended. Step 2: Mounting the Lining Slide the lining (3) onto the hub. While doing so, be careful not to damage the lining by misaligned or tilted positioning.
