WARNING!
IMPACT HAZARD
The off-the-shelf configuration of the holding-brake function does not ensure the
safety of personnel. In order to make this function safe for personnel, a normally-
open contact and a user-installed suppressor device (Metal oxyde varistor or
bidirectionnal transient voltage suppressor) must be incorporated into the brake
circuit as shown in the following diagram.
Failure to observe this precaution can result in severe injury or equipment
damage.
