1.6 Warning about misuse
In case of inadequate or improper use or manipulations of the
safety switchgear, personal hazards or damage to machinery
or plant components cannot be excluded. The relevant requi-
rements of the standard EN 1088 must be observed.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with this operating instructions
manual. The manufacturer shall accept no liability for damages resul-
ting from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary re-

Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefo-
re the compliance with the Machinery Directive is maintained.
2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
Safety switches with separate actuators are suitable for movable safety
guards, which need to be closed to ensure the necessary operational
security.
The safety switches are used for applications, in which the hazardous
situation is terminated without delay when the safety guard is opened.
Operating principle
By closing the safety guard, switch insert S1 and S3 are released and
switch insert S2 actuated (differentiated operating principle). When the
actuator is fully inserted, the safety guard is not subject to any ejection
force.
When the safety guard is opened, the NC contacts are positively ope-
ned and the NO contacts are closed.
The user must evaluate and design the safety chain in
accordance with the relevant standards and on the required
safety level.

3. Mounting
3.1 General mounting instructions
The mounting holes are accessible after removal of the cover. The
switch enclosure must not be used as an end stop. Any mounting positi-
on. The mounting position however must be chosen so that the ingress
of dirt and soiling in the used opening is avoided.
Mounting of the actuators:
See mounting instructions actuators.
Please observe the remarks of the standards EN ISO 12100,
EN 953 and EN 1088.
