}
Cables that have to be laid outside the control cabinet must be protected from mechan-
ical damage, e.g. by installing them in a conduit.
}
The unit and the input circuits must always be supplied by a single power supply.
}
Safety outputs 14 and 24 should exclusively be used for safe applications.
}
The safety outputs must
not
be connected to control inputs.
}
To suppress the pulse on switching off at safety outputs 14 and 24, use the terminal
).
}
You must comply with the idling capacity at safety outputs 14 and 24 (see
).
}
Do not connect undesignated terminals.
}
Output Y32 is an auxiliary output, e.g. for communication with a PLC or text display.
}
Auxiliary output Y32 should
not
be used for safety circuits!
}
Only contactors with positive-guided contacts should be used for safety functions.
}
Use freewheel diodes to drive inductive loads (e.g. contactors or relays) with the safety/
auxiliary outputs.
}
When connecting magnetically operated, reed proximity switches, ensure that the max.
peak inrush current (on the input circuit) does not overload the proximity switch.
}
The power supply must comply with the regulations for extra low voltages with protect-
ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
}
Ensure the wiring and EMC requirements of IEC 60204-1 are met.
}
Terminal Y5 is provided for Pilz-internal diagnostic purposes.
