General safety notes
Note
Recycling and disposal
Dispose of existing packing material in accordance with applicable regulations or recycle it.
The 3SK1 safety relays are able to be recycled thanks to a low-pollutant manufacturing
process. For environmentally-friendly recycling and disposal of your electronic waste, please
contact a company certified for the disposal of electronic waste.
Note
SILCL 3 to IEC 62061:2005 / PL e to ISO 13849-1:2008
The 3SK1 safety relays are designed in such a way as to allow implementation of
applications up to SILCL 3 in accordance with IEC 62061 and PL e/Kat. 4 in accordance with
EN ISO 13849-1.
Note
Safe state
The basis of the safety function is the definition of the safe state. In the case of safety relays,
this is the "OFF state", i.e. an open contact for sensors or shutdown of the actuators.
WARNING
Protection against electrically conductive contamination!
The devices must be protected against conductive contamination while taking account of
the ambient conditions. One way you can do this is to install the devices in a control cabinet
with the appropriate degree of protection.
WARNING
Safe functional extra-low voltage
The 3SK1 safety relays with a supply voltage of 24 V DC must be operated with safe
functional extra-low voltage (SELV, PELV). This means these modules must only be
subjected to a voltage of Um even in the event of a fault. The following applies for these
3SK1 safety relays: Um < 60.0 V.
You can find more detailed information about safe functional extra low voltage in the data
sheets of the power supplies to be used.
