1.1.3
Possible incorrect application
The following misuses are among those not approved as intended use:
–
use outdoors,
–
use in the non-industrial area (residential areas),
–
use in applications where switching off can result in hazardous movements or conditions.
Note
–
The STO function is insufficient as the sole safety function for drives subject to
permanent torque or force (e. g. suspended loads).
–
Bypassing of safety equipment is impermissible.
–
Repairs to the motor controller are impermissible!
The STO (Safe Torque Off ) function does not provide protection against electric shock,
only against hazardous movements!

Hardware documentation, GDCP-CMMP-M0-HW-...
1.1.4
Attainable safety level,
Safety function to EN ISO 13849-1 / EN 61800-5-2
The CMMP-AS-...-M0 motor controller with integrated STO safety function fulfils the requirements of
–
Category 4 / PL e to EN ISO 13849-1
–
SIL CL 3 to EN 62061
and can be used in applications up to cat. 4 / PL e to EN ISO 13849-1 and SIL 3 to EN 61800-5-2 /
EN 62061 / IEC 61508.
The achievable safety level depends on the other components used to achieve a safety function.

Requirements for product use
Make this documentation available to the design engineer, installer and personnel responsible for
commissioning the machine or system in which this product is used.
Make sure that the specifications of the documentation are always complied with. When so doing,
also take into account the documentation for the other components (e. g. motors, cables, etc.).
Take into consideration the legal regulations applicable for the destination, as well as:
–
regulations and standards,
–
regulations of the testing organizations and insurers,
–

For emergency stop applications, protection against automatic restart corresponding to the re
quired safety category must be furnished. Among other means, this can take place through an ex
ternal safety switching device.
