may cause a stopped motor to start. CD 302 with
Safe Stop provides a certain degree of protec-
tion against such unintended start, if the Safe
Stop Terminal 37 is on low voltage level or dis-
connected.

Safe Stop of CD 302
The CD 302 can perform the safety function Safe
Torque Off (As defined by draft CD IEC 61800-5-
2) or Stop Category 0 (as defined in EN 60204-1).
It is designed and approved suitable for the requi-
rements of Safety Category 3 in EN 954-1.
This functionality is called Safe Stop. Prior to inte-
gration and use of Safe Stop in an installation, a
thorough risk analysis on the installation must
be carried out in order to determine whether the
Safe Stop functionality and safety category are
appropriate and sufficient. In order to install and
use the Safe Stop function in accordance with the
requirements of Safety Category 3 in EN 954-1,
the related information and instructions of the
CD 302 Design Guide must be followed!
The information and instructions of the Opera-
ting Instructions are not sufficient for a correct
and safe use of the Safe Stop functionality!
