Safety relais
2. General safety regulations and protection measures
• The manufacturer and user of the system/machine on which the protection system is used are
responsible for coordinating and adhering to all applicable safety rules and regulations under their own
responsibility.
• The protection system guarantees functional safety in combination with the superordinate control
system, but not the safety of the entire system/machine. Thus, a safety review of the entire system/
machine in accordance with machine directive 2006/42/EC or relevant product standards is necessary
prior to use of the device.
• The operating instructions must be permanently available at the operating location of the protection
device. They must be thoroughly read and applied by every person who is tasked with the operation,
maintenance or repair of the protection device.
• The installation and start-up of the protection device may only be conducted by specialized personnel
who are familiar with these operating instructions and the applicable regulations on job safety and
accident prevention. The instructions in these operating instructions must be followed and adhered to
unconditionally.
• Electrical work must only be carried out by skilled electricians. Safety regulations for electrical engineering
and from the professional association must be followed.
• In case work has to be carried out on the switching device, it must be switched to a voltage-free position
and checked for freedom from any voltage and secured against being switched back on again.
• If the potential-free connections of the safety switching contacts are supplied with a hazardous voltage
from an external source, it must be ensured that these are also switched off when working on the
switching device.
• The switching device does not contain any components that the user must service. Any warranty or
liability on the part of the manufacturer is forfeited in the event of any unauthorized modifications or
repairs to the switching device.
• Auxiliary outputs must not execute any safety-orientated functions. They are not fail-safe and are not
checked either by testing.
The system must be checked for correct function in suitable intervals by qualified persons for
the standard-conform design of the safety system. The check must be documented in a way that
allows it to be traced at any time.
In the case of non-compliance or deliberate abuse, the manufacturer’s liability will cease.
