6.3 Ethernet
The Ethernet devices are connected via the Ethernet ports.
The ports can be used by the Ethernet devices as required.
Connecting the Ethernet ports to each other will cause the device to fail.
u Do not connect the Ethernet ports of the device to each other.

u Connect Ethernet devices to the ports X1...X6.
u For connection, use an M12 connector (with at least protection rating: IP 65 / IP 66 / IP 67). Max.
cable length: 100 m.
6.4 Voltage output
The supply voltages US and UA are looped through from port power IN to power OUT. This allows
another device to be supplied via port power OUT (daisy chain).
Max. current of US and UA: 16 A each

Optional: Connect another device to port XD2.
u
For connection, use L-coded M12 connectors (with at least protection rating: IP 65 / IP 66 / IP 67).
u Observe the derating behaviour of the device ( Ò Derating behaviour / 9) !
6.4.1 Derating behaviour
The current IUS available at ports <variable linkid="353106188" name="1024">Ports - Bereich DI</
variable> and the currents I
US-daisy-chain
and I
UA-daisy-chain
available at port XD2 depend on the ambient
temperature of the device.
