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 safet�� regulations and rules.
• When used in conjunction with the higher-order controller, the protection guarantees functional
safet��, but not the safet�� of the entire plant / machine. The safet�� of the entire plant / machine
must, therefore, be assessed in accordance with machiner�� directive 98/37 EC or appropriate
product norm before using the device.
• The operating instructions must alwa��s be available at the place of installation of the protec-
tion.
The�� must be read thoroughl�� and observed b�� all persons involved in the operation, maintenance
and servicing of the protection.
• The protection must onl�� be installed and commissioned b�� professionals familiar with these
operating instructions and the applicable operational safet�� and accident prevention regulations.
All of the instructions provided in these operating instructions must be observed and followed.
All electrical work must onl�� be performed b�� skilled electricians.
• All relevant electrical engineering and Emplo��er's Liabilit�� Insurance Association safet�� 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 contacts of the rela�� outputs are supplied externall�� 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 an�� components that require servicing b�� the user. Un-
authorised conversions and repairs made to the switching unit will void all guarantees and the
manufacturer's liabilit��.
• The protection s��stem is to be professionall�� inspected at appropriate intervals and be documented
in such a wa�� that it is comprehensible at all times.

Safety advice

• The switching unit enables operation at 230 V as well as with 24 V AC/DC. Connecting the ope-
rating voltage to the wrong terminals can destro�� the switching unit.
• The switching unit is to be installed in a switching cabinet.
• Do not install in the immediate vicinit�� of strong sources of heat.
• For capacitive and inductive loads, ensure adequate protective circuits.
The switching unit complies with EN 954 1 "Safety-related parts of control systems",
Cat. 3. To meet Cat. 3 requirements, the switching unit has a redundant structure with
two, two-way polling, forcibly actuated safety relays per channel.
The requirements of EN 12978 "Safety devices for power operated doors and gates" and
EN 12453 "Safety in use of power operated gates" are also fulfilled.
The manufacturer assumes no liability in the event of non-observance or intentional abuse.
