9. Electrical connection
WARNING
Loss of the safety function due to incorrect connection.
Ì Not suitable for safety relays that implement short circuit monitoring with different potentials (0V/24V).
The voltage at +LA/+LB must correspond to the information in the technical data.

WARNING
In the event of a fault, loss of the safety function due to incorrect connection.
Ì To ensure safety, both safety outputs must always be evaluated.
Ì Monitoring outputs must not be used as safety outputs.
Ì Lay the connecting cables with protection to prevent the risk of short circuits.
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connection.
Ì The inputs on a connected evaluation unit must be positive switching, as the two outputs on the safety
switch deliver a level of +24V in the switched-on state.
Ì All the electrical connections must either be isolated from the mains supply by a safety transformer
according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent
insulation measures (PELV).
Ì All electrical outputs must have an adequate protective circuit for inductive loads. The outputs must
be protected with a free-wheeling diode for this purpose. RC interference suppression units must
not be used.
Ì Power devices which are a powerful source of interference must be installed in a separate location
away from the input and output circuits for signal processing. The cable routing for safety circuits
should be as far away as possible from the cables of the power circuits.
Ì To avoid EMC interference, the physical environmental and operating conditions at the installation site
of the device must comply with the requirements according to the standard EN60204-1.
Ì Please pay attention to any interference elds from devices such as frequency converters or induction
heating systems. Observe the EMC instructions in the manuals from the respective manufacturer.
Important!
Ì If the device does not appear to function when operating voltage is applied (e.g. green STATE LED
does not illuminate or ash), the safety switch must be returned unopened to the manufacturer.
Ì The device is fully encapsulated, it is therefore not possible to remove the lid from the housing.
