3.5 Set-up and start-up
Warning!
The functional check 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 fixing 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 fixing surface (mounting side) (8) is open, adequate sealing must be provided in accordance with
the Kendrion Binder recommended installation procedure E76 00A0030 000. In this case, the maximum
possible protection rating is IP 56. After connection of the brake, an operational test must be performed to
check that the friction disc (5) runs smoothly. For this purpose, turn the shaft (while the brake is energised
and the machine (e.g. motor) is unpowered). Install the required guards and protections after completion of
installation.
Specifications on rating plates (example):
Zone 1:
occasional explosion hazard
Zone 2:
occasional explosion hazard for short periods
Zone 21:
occasional explosion hazard caused by combustible dust in normal operation
Zone 22:
explosion hazard caused by combustible dust unlikely to occur in normal operation;
if it does only for short periods
