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 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 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 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 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-specific installation standards as well as all
prevailing safety regulations and accident prevention rules.
Further technical information can be found in the Elan cata-
logues or in the online catalogue on the Internet: www.elan.de
The information contained in this operating instructions manual is provi-
ded without liability. 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.

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 SHG, SCG, SDG safety switch 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.
Safety switches can only be used for applications, in which
the hazardous condition is terminated without delay (e.g. run-
on movements) when the safety guard is opened.
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
Four mounting holes are provided for fixing the switch. The safety
switch must not be used as end stop. The safety switch can be moun-
ted in any position. The mounting position however is chosen so that
the components are protected against soiling and damages. In case of
painting activities, the components must be covered. The supplied fi-
xing material must be used. If a different actuating direction is required,
the four screws of the actuating head must be loosened. Turn the actu-
ating head in the desired direction and retighten the screws (tightening
torque 0.5 Nm). The default screws installed in the actuating head can
be replaced with the supplied tamperproof screws.
Mounting of the actuators: See mounting instructions actuators.
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.
The contact labelling can be found in the wiring compartment of the
switch. For the cable entry, suitable cable glands with an appropriate
degree of protection must be used. After wiring, dust and soiling must
be removed from the wiring compartment.
4.2 Contact variants
Contacts are shown with safety guard closed.
