On the brake you can find a name plate with a 16 digit material number. Only with that type num-
ber you can specify the brake.
Please consult the drawings in each section when using this instructions.
As well as these instructions, please also consider the catalogue data for the brake at
www.ringspann.com and the drawings in the individual sections.

The nominal value is marked on the type label, and on a sticker on the electronics. There are two
kinds of electronics: 220 … 240VAC and 380 … 480 VAC.
2)
The max. allowable friction pad wear depends on the brake disc thickness. See also chapter 11.2.
3)
Higher ambient temperature as 20°C reduces the max. switching frequency per hour.
4)
No adjustments necessary, the brake can only be used with 50Hz or 60Hz.
5)
At low temperatures below -30°C to -40°C, a reduction in clamping force is necessary. Consultation with
RINGSPANN is necessary.
