Set-Up And Start-Up - Kendrion EEX Series Operating Instructions Manual

3.5 Set-up and start-up

Warning!
Functional testing of the brake must not be performed unless the machine (e.g. motor) has been switched off
and secured against accidental or unintentional start-up.
The following checks must be carried out:
Check compliance with the specifications provided on the rating plate with respect to the mounting position
and protection class. Provided that the mounting surface (mounting side) (8) for the spring-applied single-disc
brake is closed, no further measures need to be taken to ensure compliance with the required protection class.
If the mounting surface (mounting side) (8) is open, adequate sealing must be provided in accordance with the
installation procedure E76 00A0030 000 recommended by Kendrion. This can also be accomplished by using
a sealing device available from Kendrion. In this case, the maximum possible protection rating is IP 56. After
connection of the brake, a functional test must be performed to check that the friction disc (5) moves smoothly.
For this purpose, turn the shaft while the brake is energized and the machine (e.g. motor) is unpowered. After
completion of mounting, all necessary covers and guards must be installed.
