Please read and follow the operating instructions carefully! Non-observance may lead to malfunctions or failure of the brake and associated damage. These operating instructions are an integral part of the brake delivery. Always keep the operating instructions easily accessible near the brake. 1.1 Definitions of terms

2 Safety 2.1 Safety and information symbols Symbol Signal word Meaning Serious personal injury and damage to property can occur: • If the brake is used improperly. • If the brake has been changed or modified. • If the relevant STANDARDS of safety or installation conditions are not observed. 2.2.1 Personnel requirements To avoid personal injury and damage to property only qualified and trained persons are allowed to work on the components. They must be sufficiently familiar with their design, transport, installation, commissioning, maintenance and disposal in accordance with the relevant...

Stepless holding brakes (SHB) are intended for use in machines and systems and may only be used for the purpose ordered and confirmed. Use outside the respective technical specifications is considered incorrect. Before mounting, the brake must be checked for proper condition (visual inspection). Not considered to be proper: Stepless holding brakes (SHB) are used for holding and decelerating on profile rails. Stepless holding brakes (SHB) prevent unintentional falling or crashing of gravity-loaded axles. • Not suitable for use in potentially explosive atmospheres • External damage • Outer...

Technical data The indicated values are guideline values which have been determined in test facilities. The suitability for the intended application must be determined, if necessary, by independent testing. When designing the brakes, the installation situations, permissible friction work and braking distances as well as ambient conditions must be carefully checked and coordinated. • Mounting and connection dimensions at the place of use must be matched to the size of the brake. • The use of the brake under extreme environmental conditions or outdoors with direct contact with weather...
