An additional relay is necessary, if the voltage of the brake is 24V, or if the current of the
brake is greater than the switching capacity of X101 (see ZX101 (SELV/PELV)– on page
194) or if you consider UL508C and the current of the brake is greater 4 A.
Perhaps consider a limited operating voltage range of the brake because of the internal
voltage drop up to max. 2.6 V.
NOTE
If the motor brake is connected directly via X101-2 and X101-3 (see ZFigure 77– on
page 173) the shown direct installation is allowed only. It is not allowed within a multi-
axis installation e.g. to connect the plus and ground connections of all motor brakes
with each other.
