Electrical connection
• The electrical connection must be performed by experienced personnel. Knowledge of all
safety notes contained in these operating instructions is part of this competence.
• The external supply voltage of 24 V DC +/- 20% must guarantee safe isolation from the
mains voltage in accordance with IEC 60742 and be able to bridge a power outage
period of at least 20 ms. Leuze electronic offers suitable power supplies (see list of
accessories in the Appendix Chapter 12). Transmitters and receivers must be supplied
from a shared power supply and must be fused against overcurrent (see Chapter 7.2).
• Basically both safety switching outputs OSSD1 and OSSD2 must be looped into the
working circuit of the machine.
• Signal outputs may not be used for switching safety-relevant signals.
• The start/restart button for unlocking the restart interlock must be mounted in such a way
that it cannot be reached from the danger zone and the entire danger zone is fully visible
from its installation position.
• It is vital during the electrical installation that the power of the machine or system to be
protected is switched off and locked, so that the dangerous movements cannot be
started unintentionally.
