Information!
To facilitate installation, you may fix the brake in position initially with a single
screw before swinging it to the point at which the other screws can be inserted as
well.
Attention!
The air gap between brake pad and brake disc is to be adjusted after the first in-
stallation and after replacement of brake pads.
After the Adjustment of the air gap the setting screw Pos. 17 and Pos. 41 must be fixed with the
nut Pos. 16 and Pos. 40, see Fig. 8.1 or Fig. 8.2.
8.4 Electrical Connection
Attention!
To protect the brake electronics, the installation of surge arresters is manda-
tory. These surge arresters must be connected between the customer's
switching relay and the brake electronics
Attention!
To protect the electronic against too fast switching, a security feature is integrated in
the electronic. The security feature locks the supply voltage and the brake cannot be
closed. After 40 s the electronic will pass the supply voltage and after a further acti-
vation the brake will close.
Attention!
Only trained electrician are allowed to connect the brake with the supply voltage.
The trained electrician must be familiar with the relevant standards (e.g. in Germany
DIN VDE 0113).
