2 Safety
Before using the Safety Locking Device, a risk evaluation must be performed
according to valid standards (e.g. EN
ISO 14121). For moun ting, o peratin g and testi ng, docu ment L 100 Sa fe im ple-

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.
Serious accidents may result if the voltage supply is interrupted!
If the voltage supply to the electromagnet of an electromagnetically locked
Safety Locking Device is interrupted, the protective device may be opened
immediately.
The following sta nda rds a pply for the risk e val ua tion a t th e prot ec tiv e d ev ic e prio r
to using the Safety Locking Device:
• 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 the integration in control circuits according to
ISO 13849-1 is dependent on the used contact block and wiring.
EN
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 Locking Devices:
Safety
ISO 12100-1, EN ISO 13849-1,
WARNING
• Machinery directive 2006/42/EC
• L ow voltage directive 2006/95/EC
• Electromagnetic compatibility directive 2004/108/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
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 Locking Device 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 L ocking Dev ic e it m us t be ens ure d th at i ts s afetyrelated capability meets or exceeds the required performance 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 Locking Device that is connected to the moveable guard in a
non-detachable 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.
L100 Safety Locking De vi ces mu st b e co nne cted in such a way that a dangerous
state can only be activated while the protective device is closed and so that they
prevent premature opening during the lag time before the dangerous state has
ended. Electromagnetic Safety Locking Devices may only be used instead of
spring-locked Safety Locking Devices in exceptional cases and following appro
priate risk evaluation.
Connection conditions:
• dangerous state can be activated only with closed protective device and
locked locking device
• protective device cannot be opened while locking device is locked

Safety
Furthermore, the L100 Safety Locking Device must not be used under the
following conditions:
• high concentration of dust particles in the surrounding area
• rapidly changing ambient temperature (leads to condensation)
• in the event of strong phys ic al sho cks
• in explosive or easily flammable atmospheres
• the mounting locations are not sufficiently stable
• in the event of electromagnetic interference
• the safety of multiple persons is dependent on the function of this Safety
Locking Device (e.g. nuclear power plants, trains, aircraft, motor vehicles,
incinerators, medical devices)
Handling the Safety Locking Device:
ª Never unlock the Safety Locking De vice before the dangerous stat e has ended.
ª Observe the permissible environmental conditions for storage and operation
(see chapter 14).
ª Immediately replace damaged Safety Locking Devices according to these
instructions.
ª Use cable gland, insulation materials and connecting wires of the appropriate
protection rating.
ª Protect the Safety Locking Device from penetrating foreign bodies (e.g. shav-
ings, sand and blasting agent).
ª Before performing painting work, cover the actuation slot, actuator and name
plate.
ª Immediately clean any contamination from the Safety Locking Device that
impacts function according to these instructions.
ª Make no structural changes to the Safety Locking Device.
ª The Safety Locking Device must be exchanged after a maximum of 20 years.

2.1.2 Foreseeable misuse
Any use other than that defined under the "approved purpose" or which goes
beyond that use of the Safety Locking Device is considered improper use!
E.g. - using without non-detachably mounted actuator
• looping into the safety circuit parts that are not relevant to safety
• using the locking device as a limit stop

Safety
2.2 Competent personnel
Prerequisites for competent personnel:
• suitable technical training
• knows the rule s and regulations for labor protection, safety at work and
safety technology and can assess the safety of the machine
• knows the instructions for the Safety Locking Device and the machine
• was instructed by the responsib le indi viduals on the mounting and opera tion
of the machine and of the Safety Locking Device
2.3 Responsibility for safety
Manufacturer and operating company must ensure that the machine and implemented Safety Locking De vi ce func tio n pro perly and that all affected persons 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 construction
• safe implementation of the Safety Locking Device
• 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
2.4 Exemption of liability
Leuze electronic GmbH + Co. KG is not liable in the following cases:
• Safety Locking Device is not used as intended
• safety notices are not adhered to
• mounting and electrical connection are not properly performed
• reasonably foreseeable misuse is not taken into account

3 Device description
The Safety Locking Device of the L100 series is an electro-mechanical switching
device in a housing made of glass-fibre-reinforced and non-combustible plastic;
the device satisfies protection rating IP 66. By means of the funnel-shaped inser
tion opening, the ac tuator self-center s, even if the door is s lightly misadjus ted. The
magnet switched currents can be reduced for both variants (adjustable via a
switch). The spring-actuated models (L100-Pxxx-SLM24) are equipped with an
auxiliary release located below the deflection head.
