1 SAFETY INSTRUCTIONS:
1.1 Symbols used:
1.2 General instructions:
- Brake installation.

2. PRODUCT DISCRIPTION:
2.1. Operating principle:
The EVO brake family belongs to the compression spring type of brakes. In the absence of an electric
current, springs, located in their casing, exercise a force on the mobile plates that stops the movement
of the friction disc. When the electromagnet is connected, the magnetic field generated attracts the
mobile plates, displacing them and releasing the friction disc. The displacement of the mobile plates
may be monitored by use of detectors ( micro-switches ).
Danger – Warning.
Electrical hazard.
Information.
Every intervention must be carried out by authorised personnel who
are in possession of this manual.
