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
instructions must be available in a legible condition and a complete ver-
sion in the vicinity of the device.
1.2 Target group: authorised qualified 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 operat-
ing 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 specifications 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 correct 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-specific 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 pro-
vided without liability and is subject to technical modifications.
If multiple safety components are wired in series, the Perfor-
mance Level to EN ISO 13849-1 will be reduced due to the
restricted error detection under certain circumstances. The
entire concept of the control system, in which the safety com-
ponent 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.

Only if the information described in this operating instruc-
tions manual are realised correctly, the safety function and
therefore the compliance with the Machinery Directive and
the Explosion Protection 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
The solenoid interlock has been designed to prevent in conjunction
with the control part of a machine, movable safety guards from being
opened before hazardous conditions have been eliminated. The com-
ponents can be used in explosion-endangered areas of Zone 2 and 22
equipment category 3 GD. The installation and maintenance require-
ments to the standard series EN 60079 must be met.
Conditions for safe operation
Due to the specific impact energy, the components must be fitted with a
protection against mechanical stresses. The specific ambient tempera-
ture range must be observed. The user must provide for a protection
against the permanent influence of UV rays.
Solenoid 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 immedi-
ately on failure of the power supply or upon activation of the
main switch.
Manual release
The locking bolt is pulled into the unlocking position by turning the
triangular key. 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
plastic cover, which is included in delivery.

3. Mounting
3.1 General mounting instructions
Fitting is only authorised in a de-energised condition
The enclosure can be fixed by means of 2 mounting holes.
The solenoid interlock is double insulated. The use of an earth wire is
not authorised. The enclosure 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 openings must be sealed by means of slot sealing plugs after
fitting.
Please observe the recommendations regarding maximum
impact energy, actuating speed and tightening torque in the
technical data.
Mounting of the actuators: See mounting instructions actuators.
Please observe the remarks of the standards EN ISO 12100,
EN 953 and EN 1088.

5. Set-up and maintenance
5.1 Functional testing
The safety function of the safety components must be tested. The fol-
lowing conditions must be previously checked and met:
- The installation is executed according to the instructions
- The connection is executed correctly
- The cable is correctly executed and connected
- The sealing is correctly located in the enclosure. (Do not remove the
sealing!)
- The safety component is not damaged
- Remove particles of dust and soiling
- Check cable entry and connections
5.2 Maintenance
In case of correct installation in accordance with the above-described
instructions, the component requires little maintenance. By use in
extreme conditions, we recommend routine maintenance including the
following steps:
1. Check the proper fixation of the actuator and the safety switchgear
2. Remove particles of dust and soiling
3. Check cable entry and connections in a de-energised condition
Caution: avoid electrostaic charging. Clean with damp cloth.
Do not open the device when live.
Damaged or defective components must be replaced.
For explosion protection reasons, the component must be ex-
changed after max. 1 million operations.
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.
