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.
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.
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).
