Before using the Safety Locking Device, a risk evaluation must be performed
according to valid standards (e.g. EN ISO 12100-1, EN ISO 13849-1,
EN ISO 14121). For mounting, operating and testing, document "Safe implemen­tation and operation of the L10" as well as all applicable national and international
standards, regulations, rules and directives must be observed (e.g. machinery
directive, low-voltage directive, work-equipment directive, safety regulations,
accident-prevention regulations, EN 1088, EN ISO 13849-1, EN 60204-1,
EN 954-1). Observe and print out relevant and supplied documents and distribute
to the affected personnel.

ª Before beginning work with the Safety Locking Device, completely read and

understand the documents applicable to the respective task.

The following standards apply for the risk evaluation at the protective device pr ior
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
EN ISO 13849-1 and EN 954-1 is dependent on the used contact block and
wiring.

In particular, the following national and international legal regulations apply for the
start-up, technical inspections and work with Safety Locking Devices:

• 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

2.1 Proper use

To ensure proper personnel protection, the Safety Locking Device must be
mounted, connected and started-up by trained personnel. 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.

The rules and regulations for protection and safety at work and the recognised
safety-related rules and regulations must be observed. These include:

• EN 1088, Interlocking devices associated with guards

• EN ISO 13849-1, Safety-related parts of control systems

• EN 60204-1, Electrical equipment of machines

L10 Safety Locking Devices must be connected in such a way that a dan gerous
state can only be activated while the protective device is closed and so that the
dangerous state has ended before the protective device can be opened. They
must not be used if the point of operation can be accessed during the lag time
before the dangerous state has ended.

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

• manual unlocking of the locking device while the machine is running triggers
a STOP command; the dangerous state is ended before the protective
device can be opened

Furthermore, the L10 Safety Locking Device must not be used under the following
conditions:

• lag time of the dangerous state is greater than the minimum time delay of
the manual actuator release

• high concentration of dust particles in the surrounding area

• rapidly changing ambient temperature (leads to condensation)

• in the event of strong physical shocks

• in explosive or easily flammable atmospheres

• the mounting locations are not sufficiently stable

• 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 Observe the permissible environmental conditions for storage and operation

(see chapter 14 "Technical data").

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, knurled nut 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.

2.2 Competent pe rsonn e l

Prerequisites for competent personnel:

• suitable technical training

• knows the rules and regulations for occupational safety, 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 responsible individuals on the mounting and operation
of the machine and of the Safety Locking Device

Safety

2.3 Responsibility for safety

Manufacturer and operator of the machine must ensure that the mach ine and
implemented Safety Locking Device function properly 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.
