impermissible contact to live parts, local standards must be
complied with.

2.3.1 Connecting the power supply

The 230-V versions of LOGO! are suitable for operation
with rated voltages of 115 V AC/DC and 240 V AC/DC. The
LOGO! 24-V and 12-V versions can be operated with a
24 VDC, 24 V AC or 12 VDC power supply. For information
on permissible voltage tolerances, line frequencies and
power consumption, refer to the installation instructions in
the Product Information supplied with your device and to
the technical data in Appendix A.
The CM EIB/KNX has been designed as a slave module for
the LOGO! controller and must be supplied with a mains
voltage of 12/24 V AC/DC.
The AS Interface bus requires a special AS Interface power
supply (30 V DC) that enables simultaneous transmission
of data and power for the encoders via a single line.
