7 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
mai
ns 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
acc
e
ssories in the Appendix Chapter 12). Transmitters and receivers must be supplied
from a shared power supply and must
be f
used against overcurrent (see Chapter 7.2).
• Basically both safety switching outputs OSSD1 and OSSD2 must be looped into the
wor
king 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
th
at 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
protect
ed is switched off and locked, so that the dangerous movements cannot be
started unintentionally.
