When using a 5-pole L-coded M12 connector:
u
Ground the unit via the mounting screw of the upper mounting lug.
u
Connect pin 5 of the port XD1/ XD2 via an L-coded M12 connector with functional earth.
Connect the device to the mass point (e.g. body, FE of the installation) using the shortest route.
6.6 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.
Optionally, an additional supply voltage UA can be fed to the device via port power IN. UA is used
exclusively to supply additional devices via port power OUT (daisy chain).
The port XD1 has overvoltage protection (US).
The port XD1 has reverse polarity protection (US).
The port XD1 has cross reverse polarity protection (US, UA).
The port XD1 has an inrush current limitation.
u
Disconnect power.
u
Connect the device via port XD1 to supply voltage US with 12 / 24 V DC (8…32 V SELV according
to DIN 60950).
u
Optional: Connect the device via port XD1 to supply voltage UA with 12 / 24 V DC (8…32 V SELV
according to DIN 60950).
u
For connection, use L-coded M12 connector (with at least protection rating: IP 65 / IP 66 / IP 67 / IP
69K).
