SK 31 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 instructions 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 contact of the relay output is supplied externally with a dangerous voltage,
make certain that this voltage is switched off during work on the switching unit.
• The switching unit does not contain any components that require servicing by the user. Un-
authorised 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.

Safety advice

• The switching unit enables operation at 230 V or at 24 V. Connecting the operating voltage to the
wrong terminals can destroy the switching unit.
• Do not install in the immediate vicinity of strong sources of heat.
• For capacitive and inductive loads, ensure adequate protective circuits.
• It is not permissible to operate the safety relay while the housing is open.
For the design of the safety system to conform to engineer standards
acc. to EN ISO 18349-1:2008 category 2, the safety system must be tes-
ted prior to each dangerous movement of the plant / machine. Without
testing, the operation or wiring of the SK 31 safety relay does not satisfy
these safety requirements.
The manufacturer assumes no liability in the event of non-observance
or intentional abuse.
