1 About this document
1.1 Function
This operating instructions manual provides all the information you
need for the mounting, set-up and commissioning to ensure the safe
operation and disassembly of the safety switchgear. The operating inst-
ructions must be available in a legible condition and a complete version
in the vicinity of the device.
1.2 Target group: authorised qualied personnel
All operations described in this operating instructions manual must
be carried out by trained specialist personnel, authorised by the plant
operator only.
Please make sure that you have read and understood these operating
instructions and that you know all applicable legislations regarding
occupational safety and accident prevention prior to installation and
putting the component into operation.
The machine builder must carefully select the harmonised standards to
be complied with as well as other technical specications for the selec-
tion, mounting and integration of the components.
1.3 Explanation of the symbols used
Information, hint, note:
This symbol is used for identifying useful additional information.
Caution: Failure to comply with this warning notice could
lead to failures or malfunctions.
Warning: Failure to comply with this warning notice could
lead to physical injury and/or damage to the machine.
1.4 Appropriate use
The products described in these operating instructions are developed to
execute safety-related functions as part of an entire plant or machine. It
is the responsibility of the manufacturer of a machine or plant to ensure
the proper functionality of the entire machinery or plant.
The safety switchgear must be exclusively used in accordance with the
versions listed below or for the applications authorised by the manufac-
turer. Detailed information regarding the range of applications can be
found in the chapter "Product description".
1.5 General safety instructions
The user must observe the safety instructions in this operating instruc-
tions manual, the country-specic installation standards as well as all
prevailing safety regulations and accident prevention rules.
Further technical information can be found in the Schmersal
catalogues or in the online catalogue on the Internet: www.
schmersal.net.
The information contained in this operating instructions manual is provi-
ded without liability and is subject to technical modications.
If multiple safety components are wired in series, the Perfor-
mance Level to EN ISO 13849-1 will be reduced due to the re-
stricted error detection under certain circumstances. The entire
concept of the control system, in which the safety component
is integrated, must be validated to EN ISO 13849-2.
There are no residual risks, provided that the safety instructions as well
as the instructions regarding mounting, commissioning, operation and
maintenance are observed.

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 specications apply accordingly, provided that they correspond to
the standard version.
2.3 Destination and use
The solenoid interlock has been designed to prevent movable safety
guards in conjunction with the control part of a machine from being
opened before hazardous conditions have been eliminated.
Interlocks with power to lock principle may only be used
in special cases after a thorough evaluation of the risk of
accident, since the safety guard can be opened immediately
on failure of the power supply or upon activation of the main
switch.
Manual release
A manual release is available as a mounting tool and in the event of
a power failure in case the power to unlock principle is used. If the
triangular key is turned 180°, the locking bolt is pulled into the unlocking
position. Please ensure that jamming by external inuence on the
actuator is avoided. The normal locking function is only restored after
the triangular key has been returned to its original position. After being
put into operation, the manual release must be secured by installing the
sealing plug, which is included in delivery.

3 Mounting
3.1 General mounting instructions
Two mounting holes are provided for xing the enclosure. The solenoid
interlock has double insulation. The use of a protective ground wire
therefore is not authorised. The solenoid interlock must not be used as
an end stop. Any mounting position. The mounting position however
must be chosen so that the ingress of dirt and soiling in the used
opening is avoided. The unused opening must be sealed by means of
slot sealing plugs. Tightening force for the Torx T10 cover screws 0.7 ...
1 Nm.
Please observe the remarks of the standards EN ISO 12100,
EN 953 and EN 1088.

4 Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by autho-
rised personnel in a de-energised condition.
At least one magnetic contact A with positive break must be
integrated in the safety circuit.
For the cable entry, suitable cable glands with an appropriate degree
of protection must be used. The thin walls of the mounting holes are
removed when the cable gland is screwed in.

5 Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The
following conditions must be previously checked and met:
1. Fitting of the solenoid interlock and the actuator
2. Check the integrity of the cable entry and connections
3. Check the switch enclosure for damage.
5.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:
Check for tight installation of the actuator and the switch
2. Remove particles of dust and soiling
3 Check cable entry and connections
Damaged or defective components must be replaced.
6 Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised condi-
tion only.
6.2 Disposal
The safety switchgear must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations.
Cut-clamp technology
The IDC method of termination (cut clamp technology) enables con-
necting exible wires with cable section 0.75 - 1 mm2without using
conductor ferrules. To this effect, strip the wire according to the drawing
(refer to the wiring example) and insert it into the cable gland, close the
cable gland, push the conductors in the groove of the cover (refer to
wiring example) and screw the cover back. Observe that the individual
conductors remain in position to avoid jamming.
70 mm
Screw Terminal method of termination (SK version)
Unscrew the cover of the enclosure. Connect the cables to the terminal
block. Use insulated conductor ferrules to that effect. Screw the cover
back on the enclosure.
