Safety Controller SK 35
General Safety Terms and Protection Measures
• It is the responsibility of the manufacturers and operators of the plant/machine, on which the
safety system is used, to observe and fulfil all valid safety regulations and rules.
• The safety system guarantees a functional safety, in conjunction with the machinery control
system, however this does not apply to the complete safety of the plant/machine.
Therefore, a safety consideration for the complete plant/machine, according to the machinery
directive 98/37 EC or to the appropriate product standard, is necessary before using this safety
system.
• This manual must be available at the installation place of the safety controller at all time.
Any person assigned with the operation and maintenance of the safety system must read and
follow this manual.
• The safety system may only be installed and initially operated by qualified personnel, who are
familiar with this manual and the valid regulations for safety at work and accident prevention.
The instructions in this manual must be strictly taken into consideration and fulfilled.
Electrical work may only be carried out by qualified personnel.
• All electrical engineering and the professional organizations safety regulations are to be
considered.
• Before performing any work on the safety controller, the voltage must be disconnected and verified
that there is no live voltage.
• If the potential free contact of the relay output is connected to a dangerous voltage, it is also
necessary to switch off this voltage before working on the safety controller.
• The safety controller contains no user-serviceable parts. Any unauthorised modifications and/or
repairs of the safety controller will terminate any guarantee and claim against the
manufacturer.
• The safety system is to be checked in proper time intervals by qualified personnel, and must be
documented in such a way that it can be viewed and understood at any time.

Safety Notes

• The Safety Controller might be operated with 230V AC (115 V for SK 35-82) or 24V. Connecting
the voltage to the wrong clamps might destroy the device.
• The Safety Controller must be mounted inside a cabinet.
• Do not install the safety controller close to strong heat sources.
• Adequate protection devices must be provided for capacitive and inductive loads at the output.
For a standardized-conformal construction of the safety system accord-
ing to EN 954-1 category 2, the machinery control system must perform
a safety system test prior to dangerous movements of the plant/machine.
The operation or the installation of the safety controller SK 35 does not
fulfil any safety requirements without being tested.
The liability of the manufacturer is terminated with neglect or deliberate
abuse.
