SCALANCE X101-1AUI Power Supply and Signaling Contact
Power Supply
The power supply is connected using a 4-pin plug-in terminal block. The power supply can
be connected redundantly. Both inputs are isolated. There is no distribution of load. When
using a redundant power supply, the power supply unit with the higher output voltage
supplies SCALANCE X101-1AUI alone. The power supply is connected over a high
resistance with the enclosure to allow an ungrounded setup.

Warning
The SCALANCE X101-1AUI device is designed for operation with safety extra-low voltage.
This means that only safety extra-low voltages (SELV) complying with IEC950/EN60950/
VDE0805 can be connected to the power supply terminals.
The power supply unit to supply SCALANCE X101-1AUI must comply with NEC Class 2
(voltage range 18-32 V, current requirement 470 mA).
If the device is connected to a redundant power supply (two separate power supplies), both
must meet these requirements.
The signaling contact can be subjected to a maximum load of 100 mA (safety extra-low
voltage (SELV), DC 24 V).
Never connect SCALANCE X101-1AUI to AC voltage.
Never operate SCALANCE X101-1AUI with DC voltage higher than 32 V DC.
