Wiring
The wiring is defined in the circuit diagram in the Configurator. There you can select the in-
puts that are to perform a safety function and the outputs that are to switch this safety func-
tion.
Note:
ATTENTION!
The plug-in connection terminals on the relay outputs that carry mains volt-
age should only be connected and disconnected when the voltage is
switched off.
} Information given in the "Technical details" must be followed.
} Outputs:
– O0 to O5 are safety outputs.
– O4 and O5 are relay outputs
– O0 to O3 are semiconductor outputs
– OA0 is an output to delete a project from the base unit (see online help for the
PNOZmutli Configurator).
} To prevent contact welding, a fuse should be connected before the output contacts (see
technical details).
} Use copper wire that can withstand 75°C.
} Sufficient fuse protection must be provided on all output contacts with inductive loads.
} The control system and input circuits must always be supplied by a single power sup-
ply. The power supply must meet the regulations for extra low voltages with safe sepa-
ration.
} Two connection terminals are available for each of the supply connections 24 V and 0 V
(semiconductor outputs), plus A1 and A2 (power supply). This means that the supply
voltage can be looped through several connections. The current at each terminal may
not exceed 3 A.
} Test pulse outputs must exclusively be used to test the inputs. They must not be used
to drive loads.
Do not route the test pulse lines together with actuator cables within an unprotected
multicore cable.
} Test pulse outputs are also used to supply safety mats that trigger a short circuit.
Test pulses that are used for the safety mat may not be reused for other purposes.
