Devices of the X-300EEC product group
When using only one power supply unit 24 VDC and two 24 VDC power supplies, the LEDs
"L1" and "L2" signal the existence of the power supply L1 and L2.
When using two 24 VDC power supply units, the LEDs "L1" and "L2" signal the existence of
the primary voltage and the secondary voltage for both power supply units. If the power
supply is intact, a fault occurring on a power supply unit on the secondary side can be
recognized.
