Power supply
Power supply of the IE switches X300 EEC / XR300M EEC
WARNING
Danger to life: 100 ... 240 V / 60 to 250 VDC
Please note that the IE switches X300EEC / XR300M EEC can have a 100 to 240 VAC / 60
to 250 VDC - or a 24 to 48 VDC power supply.
You can recognize the type of power supply from the labeling on the device and the labeling
of the terminal block for the power supply of the switch.
The 100 to 240 VAC / 60 to 250 VDC and 24 to 48 VDC terminal blocks for the power supply
of the X300 EEC / XR300M EEC are coded and cannot be confused when you plug them in.
Power supply redundancy with the IE switches X300 EEC / XR300M EEC
The IE switches X300 EEC / XR300M EEC provide the following options for redundancy of the
24 to 48 VDC power supply:
● Redundant power supply via one power supply unit (1 x 24 to 48 VDC)
You can connect a redundant power supply to each 24 V to 48 VDC power supply unit. To
do this, use the terminals L1 and L2 of terminal block PS1.
● Redundant power supply units 24 to 48 VDC
Connect one power supply to a power supply unit.
NOTICE
Connection with redundant 24 to 48 VDC power supply units
If you connect an X‑300EEC with redundant 24 to 48 VDC terminal blocks to two power
supplies, you will need to use L1 of the PS1 terminal block and L2 of the PS2 terminal block.
