For connection, use M12 connectors (with at least protection rating: IP 65 / IP 66 / IP 67 / IP 69K).
Max. cable length: 100 m.
u
Do not connect the Ethernet ports of the device to each other. This causes a failure of the unit.

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
u
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 /
IP 69K).

6.5 Ground connection
To ensure electrical interference protection, the intended function and safe operation of the device, it
must be connected to a mass point.
The FE potential is connected to the following points of the device:
•
Upper mounting lug
•
Port XD1 (pin 5)
•
Port XD2 (pin 5)
When using a 4-pole L-coded M12 connector (recommended):
u
Ground the unit via the mounting screw of the upper mounting lug.
