2 Safety
Before using the Safety Position Switch, a risk evaluation must be performed
according to valid standards (e.g. EN
ISO 14121). For mount ing, opera ting and testing, d ocument S300 Safe imple-

mentation and operati on, app licati on infor mation as wel l as all applic able na tional
and international standards, regulations, rules and directives must be observed.
Observe and print out relevant and supplied documents and distribute to the
affected personnel.
The following sta nda rds a pply for the risk e val ua tion a t the protective dev ice prior
to using the Safety Position Switch:
• EN ISO 14121, Safety of machinery, risk evaluation
• EN ISO 12100-1, Safety of machinery
• EN ISO 13849-1, Safety-related parts of control systems
The realizable category of integratio n in control circuits acc. to EN ISO 13849 -1 is
dependent on the used contact block, wiring and mechanical conditions.
In particular, the fo llowin g nationa l and i nternationa l legal regulatio ns apply for the
start-up, technical inspections and work with Safety Position Switch:
• Machinery directive 2006/42/EC
• Low voltage directive 2006/95/EC
• Use of work equipment directive 89/655 EEC
• Safety regulations
• Accident-prevention regulations and safety rules
• Ordinance on Industrial Safety and Health and Labor Protection Act
• Device Safety Act
Safety
ISO 12100-1, EN ISO 13849-1,
For safety-related information you may also contact the local authorities (e.g.,
industrial inspectorate, employer's liability insurance association, labor inspectorate, labor protection and health authority).

Safety
2.1 Approved purpose and foreseeable improper operation
2.1.1 Proper use
• The Safety Switch must only be used after it has been selected in accordance with the respectively applicable instructions and relevant standards,
rules and regulations regarding labor protection and safety at work, and
after it has been installed on the machine, connected, commissioned, and
checked by a competent person.
• When selecting the Safety Switch it must be ensured that its safety-related
capability meets or exceeds the req uire d pe rformance level PLr ascertained
in the risk assessment.
• It must be in perfect condition and inspected regularly.
• The switching process must only be triggered by an actuator approved for
this Safety Switch as w ell as a s teering device in acco rda nce with the spe ci fications. Both must be connected to the fixed actuator holder or moveable
guard in a permanent and tamperproof manner.
WARNING
A running machine can cause severe injuries!
ª Make certain that, during all conversi ons, maintenan ce work and inspec tions,
the system is securely shut down and protected against being restarted
again.
S300 Safety Switches must be connected in such a way that a dangerous state
can only be activated while the protective device is closed and so that the
dangerous state s tops up on ope ning of the protective d ev ice . It mus t not be used
if the point of o peration c an be a ccessed d uring the lag t ime befor e the dan gerous
state has ended.
Connection conditions:
• the dangerous state can only be activated while the protective device is
closed
• opening the protective device while the machine is running triggers a stop
command and ends the dangerous state

Safety
Furthermore, the S300 Safety Position Switch must not be used under the
following conditions:
• the actuation surface (e.g. of the machine or sliding gate) for the actuator is
not form-fitting with positive actuation
• rapidly changing ambient temperature (leads to condensation)
• in the event of strong physical shoc ks
• in explosive or easily flammable atmospheres
• the mounting locations are not sufficiently stab le
• the safety of multiple persons is dependent on the function of this Safety
Switch (e.g. nuclear power plants, trains, aircraft, motor vehicles, incinerators, medical device s)
For machines with longer slowdowns, a Safety Locking Device must be used.
Handling the Safety Position Switch:
ª Observe the permissible environmental conditions for storage and operation
(see chapter 14).
ª Immediately replace damaged Safety Position Switch according to these
instructions.
ª Use cable gland, insulation materials and connecting wires of the appropriate
protection rating.
ª Protect the Safety Position Switch from penetrating foreign bodies (e.g. shav-
ings, sand and blasting agent).
ª Before performing painting work, cover the actuatio n head, a ctuator a nd name
plate.
ª Immediately clean any contamination from the Safety Position Switch that
impacts function according to these instructions.
ª Make no structural changes to the Safety Position Switch and/or actuator.
ª The switching direction may only be changed following an adequate risk eval-
uation and according to the dangerous direction of movement.
ª The Safety Switch must be exchanged after a maximum of 20 years.

Safety
2.1.2 Foreseeable misuse
Any use other than that defined under the "approved purpose" or which goes
beyond that use of the Safety Switch is considered improper use!
E.g. - using without non-detachably mounted actuator or start-up device
• looping into the safety circuit parts that are not relevant to safety
• using the switch as a limit stop
2.2 Competent personnel
Prerequisites for competent personnel:
• suitable technical training
• knows the rules and re gulations for labor protect ion, safety at work and
safety technology and can assess the safety of the machine
• knows the instructio ns for the Safety Position Switch and the machine
• was instructed by the respons ible i ndividua ls on the mountin g and opera tion
of the machine and of the Safety Position Switch
2.3 Responsibility for safety
Manufacturer and operating company must ensure that the machine and implemented Safety Position Switch function properly a nd that all affected person s are
adequately informed and trained.
The type and content of all imparted information must not lead to unsafe actions
by users.
The manufacturer of the machine is responsible for:
• safe machine cons truc tion
• safe implementation of the Safety Position Switch
• imparting all relevant information to the operating company
• adhering to all regulations and directives for the safe starting-up of the
machine
The operating company is responsible for:
• instructing the operating personnel
• maintaining the safe operation of the machine
• adhering to all regulations and directives for labor protection and safety at
work
• regular testing by competent personnel
