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 Technical details [ 35] must be followed.
}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.

6.3 Ethernet interfaces
6.3.1 RJ45 interfaces ("Ethernet")
Two free switch ports are provided as Ethernet interfaces via an internal autosensing
switch. The autosensing switch automatically detects whether data transfer is occurring at
10 Mbit/s or 100 Mbit/s.
INFORMATION
The connected subscribers must support the autosensing/autonegotiation
function. If not, the communication partner must be set permanently to "10
Mbit/s, half duplex".
The switch's automatic crossover function means there is no need to distinguish on the
connection cable between patch cable (uncrossed data line connection) and crossover
cable (crossover data line connection). The switch automatically creates the correct data
line connection internally. Patch cable can therefore be used as the connection cable for
end devices as well as cascading.
Both Ethernet interfaces use RJ45 technology.
6.3.2 Requirements of the connection cable and connector
The following minimum requirements must be met:
}Ethernet standards (min. Category 5) 10BaseT or 100BaseTX
}Double-shielded twisted pair cable for industrial Ethernet use
}Shielded RJ45 connectors (industrial connectors)
