6.1 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:
} Information given in the "Technical details" must be followed.
} Outputs O0 to O3 are semiconductor outputs
} Use copper wire that can withstand 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 sep­
aration.
} 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.
6.2 Commissioning the control system
Procedure:
} Wire the inputs and outputs on the base unit in accordance with the circuit diagram.
} Connect the supply voltage:
– Supply voltage for the control system:
– Terminal A1: + 24 VDC
– Terminal A2: 0 V
– Supply voltage for the semiconductor outputs:
– 24 V terminal: + 24 VDC
– 0V terminal: 0 V
Please note: The supply voltage for the semiconductor outputs must always be present,
even if you are not using the semiconductor outputs.
When the voltages are fed separately using two power supplies, the supply voltage for the
control system and the supply voltage for the semiconductor outputs are galvanically isol­
ated.
CAUTION!
Do not connect or disconnect expansion modules and terminators during
operation.
