1 Preface and general information

1.1 About these Operating Instructions

| These Operating Instructions will help you to work safely on and with the

spring-applied brake with electromagnetic release. They contain safety instructions

that must be followed.

| All persons working on or with the electromagnetically released spring-applied brakes

must have the Operating Instructions available and observe the information and notes

relevant for them.

| The Operating Instructions must always be in a complete and perfectly readable

condition.

1.2 Terminology used

Term In the following text used for

Spring-applied brake Spring-applied brake with electromagnetic release

Drive system Drive systems with spring-applied brakes and other drive

components

1.3 Conventions used

This documentation uses the following conventions to distinguish different types of

information:

Spelling of numbers Decimal separator Point The decimal point is always used.

For example: 1234.56

Symbols Page reference Reference to another page with additional information

For example: 16 = see page 16

Document reference Reference to another documentation with additional

information

For example: Operating instructions

Wildcard Wildcard for options, selections

For example: BFK458- = BFK458-10
