(translation of the original operating instructions) MAN20001587-01-02/23
9. Electrical connection
The following connection options are available:
Ì Separate operation
Ì Series connection with wiring in the control cabinet
Ì Series connection with Y-distributors
Ì Connection without IO-Link communication
Ì Connection with IO-Link communication
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 short circuits.
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connection.
Ì Do not use a control system with pulsing or switch off the pulsing function in your control system.
The device generates its own test pulses on the safety outputs. A downstream control system must
tolerate these test pulses, which may have a length of up to 300µs. Depending on the inertia of the
downstream device (control system, relay, etc.), this can lead to short switching processes. The test
pulses are output only with the safety outputs switched off during device start.
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 (SELV).
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 prevent 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 (EMC).
Ì 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.
Ì If the solenoid is operated with a frequency of more than 0.2Hz, the device may react with a delay.
Ì In devices with IMP/IMM inputs, the power supply for the evaluation electronics is separate from the
power supply for the guard locking solenoid.
If different power supplies are used, they must have the same reference potential.
Ì For device variants with two connecting cables, both cables must be laid in the same cable duct.
Important!
If the device does not appear to function when the operating voltage is applied (e.g. STATE LED does
not ash), the safety switch must be returned to the manufacturer.
