2.3 
Wiring LOGO! 
Wire LOGO! using a screwdriver with a 3-mm blade. 
You do not need wire ferrules for the terminals. You can use conductors with cross-sections 
of up to the following thicknesses: 
●  1 x 2.5 mm
2
 
●  2 x 1.5 mm
for each second terminal chamber 
Tightening torque: 0.4...0.5 Nm or 3...4 in-lbs. 
 
 
Note 
Always cover the terminals after you have completed the installation. To protect LOGO! 
adequately from impermissible contact to live parts, comply with local standards. 
 
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 V DC 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 communication module for the LOGO! controller 
and must be supplied with a mains voltage of 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. 
The LOGO! TD must be supplied with a voltage of 12 V DC or 24 V AC/DC. 
 
CAUTION 
 
Expansion modules DM8 230R and DM16 230R must be operated with the same type of 
power supply (DC or AC) as for the connected 230-V version of the LOGO! Base Module. 
The same supply output "+/- "on DC power supplies or "N/L" on AC power supplies must 
connect to the same phase on both the expansion module DM8/16 230R and the 
connected LOGO! 230 .... Failure to follow the instructions could result in personal injury.  
 
 
Note 
A power failure might cause an additional edge triggering signal at the special functions. The 
stored data will be from the last uninterrupted cycle.
