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-monitoring module. The
operating instructions must be available in a legible condition and a
complete version in the vicinity of the device.
1.2
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
selection, 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-monitoring module must be exclusively used in accordance
with the versions listed below or for the applications authorised by the
manufacturer. 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-
prevailing safety regulations and accident prevention rules.
Further technical information can be found in the Elan
catalogues or in the online catalogue on the Internet:
www.schmersal.net.
