6.1
General wiring guidelines
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.
Please note:
}
Information given in the
}
Use copper wiring with a temperature stability of 75 °C.
}
Sufficient fuse protection must be provided on all output contacts with inductive loads.
}
The safety system and input circuits must always be supplied by a single power supply.
The power supply must meet the regulations for extra low voltages with protective separ-
ation (SELV, PELV).
}
Test pulse outputs are used to detect shorts between the inputs. Shorts between inputs
are detected if the inputs are connected to different test pulses (test pulse 0 ... test pulse
3). Shorts between inputs of the same module with the same test pulses will not be de-
tected.
}
Test pulse outputs must exclusively be used to activate the inputs. They must not be
used to drive loads.
Do not route the test pulse lines together with actuator cables within an unprotected mul-
ticore cable.
}
The maximum permitted total current of the test pulse outputs is 640 mA.
6.2
Connection
Procedure:
}
Connect the supply voltage for the control system:
– Terminal 24 V: + 24 VDC
– Terminal 0 V: 0 V,
}
Protect the supply voltage as follows:
– Circuit breaker, characteristic C - 6 A
or
– Blow-out fuse, slow, 6A
CAUTION!
Do not connect or disconnect expansion modules and terminators during
operation.
