6.4.2.4 Connecting the 100 to 240 V AC power supply with the XR-300M PoE
Connecting the power supply 100...240 V AC via the 2-pin terminal block
There are devices with single (1 x 100...240 V) or redundant power supply (2 x 100...240 V).
The cable outlet can be to the front or rear depending on the device type.
● The power supply is connected using a 2-pin plug-in terminal block.
● The power supply can be connected redundantly. Both inputs are isolated. There is no
distribution of load. When a redundant power supply is used, the power supply unit with
the higher output voltage supplies the IE Switch X-300 alone.
● The two power inputs are always non-floating.
