1. General remarks
1.1 General safety instructions
Please read these installation and operating instructions carefully before installing and operating
the brake. Please refer also to the drawings in the various sections.Safety must be given the
highest priority during all work performed on the brake. Switch off the drive unit before performing
work on the brake. The brake should be secured against accidental switch-on. Rotating compo-
nents (e.g. brake disc) must be secured by the operator to prevent accidental contact.
1.2 Special safety instructions
Danger to life and limb!
It is essential to secure the entire drive train against inadvertent starts dur-
ing brake installation and maintenance. Rotating components can cause
severe injuries. Therefore, rotating components (e.g. brake disc) must be
secured by the operator to prevent accidental contact.
2. Function, Marking, Technical Details and Parts list
2.1 Function, Operating Principle
The brakes of type EV an EH are machine components, used for the purpose of braking acceler-
ated masses safely and reliably. The combination of brake and brake disc provides a complete
brake unit capable of securing machines and equipment system effectively. Thanks to its univer-
sal design, it can perform the following functions:
•
As a holding or parking brake, it prevents the unintended start of a stationary shaft.
•
As a stopping brake, it brings a rotating shaft to a complete standstill.
Braking force is generated by electromagnetic force (2), the brake is released by spring force. If
the lining of the friction block (1) wears out, the holding or braking torque is reduced because the
spring load is reduced.
2.2 Marking
These installation and operating instructions apply to:
•
the types EV/EH 018/024/028/038 EFM, each with two separate voltage ranges 240V (220
… 240VAC) and 480 (380 … 480VAC).
•
installation on horizontal brake discs and vertical brake discs in combination with horizon-
tal shafts.
•
for models with and without switches.
•
for different brake pad material and for brake pads with signal cables.
•
With cable bushing (cCSAus type) and plug as connection for the supply voltage
Example:
Only cCSAus version
