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.

4: RX -
5: not used
u
Connect Ethernet devices to the ports X01...X06.
u
For connection, use an M12 connector (with at least protection rating: IP 65 / IP 66 / IP 67 / IP
69K). Max. cable length: 100 m.
6.4 Ground connection
The FE potential is connected to the following points of the device:
•
Upper mounting lug of the housing
u
Ground the device via the mounting screw of the upper mounting lug.
u
To ensure the protection of the device against electrical interference and to ensure the safe
function of the device, the housing has to be connected to ground of the supply using the
shortest possible route.
6.5 Voltage supply
The device is connected to the supply voltage US via the power IN port. The supply voltage US
supplies the device with voltage.
Max. current consumption: 100 mA (12 V) / 50 mA (24 V)
Port X31 has overvoltage protection (US).
The port X31 has reverse polarity protection (US).
The port X31 has an inrush current limitation (max. current: 3 A).
ATTENTION
Current surge with high voltage input due to disconnection of the device from battery supply
while the engine is running
w
Damage to the device
u
When supplied by the on-board system in vehicles, do not disconnect the device from
the battery when the engine is running.
