Connecting Devices With 100 To 240 Vac Power Supply; 100 To 240 Vac - Product Group X-300Eec - Siemens SCALANCE X-300EEC Compact Operating Instructions

Connecting a redundant power supply to 2 power supply units
To connect the power supplies, use pins L1/M1 of the left terminal block "X1" and pins L1/M1
of the right terminal block "X2". Only "L1" is monitored on each terminal block.
Since both power supply units have connectors for redundant power supply, you can
connect 2 power supplies to each of the two power supply units. This should, however, only
be necessary in extremely rare situations.
Figure 5-3
● If the power supply fails at pins L1/M1 of terminal block "X1", this is indicated by LED L1.
● If the power supply fails at pins L1/M1 of terminal block "X2", this is indicated by LED L2.
