Safety Relay
2. General safety regulations and protective measures
• The manufacturer and users of the plant / machine on which the protection is being used are responsible
for implementing and following all applicable safety regulations and rules.
• When used in conjunction with the higher-order controller, the protection guarantees functional safety,
but not the safety of the entire plant / machine. The safety of the entire plant / machine must, therefore,
be assessed in accordance with machinery directive 2006/42/EC or appropriate product norm before
using the device .
• The operating instructions must always be available at the place of installation of the protection. They
must be read thoroughly and observed by all persons involved in the operation, maintenance and
servicing of the protection.
• The protection must only be installed and commissioned by professionals familiar with these operating
instructions and the applicable operational safety and accident prevention regulations. All of the instruc-
tions provided in these operating instructions must be observed and followed.
• All electrical work must only be performed by skilled electricians. All relevant electrical engineering and
Employer's Liability Insurance Association safety regulations must be observed.
• During work on the switching unit, it is to be switched to zero potential, checked to ensure that it is at
zero potential and protected against being restarted.
• If the potential-free connectors of the relay switching contacts are supplied externally with a dangerous
voltage, make certain that these outputs are also switched off during work on the switching unit.
• The switching unit does not contain any components that require servicing by the user. Unauthorised
conversions and repairs made to the switching unit will void all guarantees and the manufacturer's
liability .
• The protection system is to be professionally inspected at appropriate intervals and be documented in
such a way that it is comprehensible at all times.
The manufacturer assumes no liability in the event of non-observance or intentional
abuse.
