14.2.2 General safety notes
!
WARNING!
It is absolutely essential that you also observe the safety instructions
in the system manual for your automation system.
The following areas of application are expressly excluded for the CPU
module:
Use in areas where there is a risk of explosion or fire
Use in the mining sector
Use in the open air
Other products are to be used for these applications!
The CPU module is not designed for safety-relevant control tasks (e.g.:
shutdown in case of an emergency). For safety-relevant control tasks
and personnel security, additional external safety measures must be
implemented to ensure the system remains in a safe operating condi-
tion even in the event of a fault.
According to EN ISO 13849-1, the CPU module complies with category
B and is therefore alone insufficient for the realization of safety func-
tions for the protection of personnel.
For further information, please see EN ISO 13849-1.
The module is defined as "open type" equipment (according to UL 508)
or as "offenes Betriebsmittel" (according to EN 61131) and must there-
fore be installed in a switch cabinet.
For additional information on programming the module, please see the
system manual.
