Manual
162 Manual, 01/2011, 6SL3097-4AC10-0BP2
Note
An additional external electronics power supply via terminal X124 is required in two cases:
If the digital outputs DO 8 to DO 11 are in use, the power supply needs to be connected
to X124.
The electronics power supply to the CU305 is supplied using the Power Module. If the
CU305 needs to remain functional when the Power Module is switched off, the power
supply needs to be connected to X124.

See also "Example of circuits for the F-DI/F-DO..." in the
chapter titled "Example connections".
8 M1 Reference potential for the failsafe digital inputs/outputs
An F-DI consists of one digital input and a second digital input where the cathode of the optocoupler is also fed out.
F-DI 0 = terminals 1, 2, and 3 (DI 16, DI 17+, and DI 17-)
F-DI 1 = terminals 4, 5, and 6 (DI 18, DI 19+, and DI 19-)
Max. connectable cross-section: 1.5 mm
2
Type: Spring-loaded terminal 1 (see Appendix A)
1) DI: Digital input; F-DI: Failsafe digital input
NOTICE
An open input is interpreted as "low".
Note
If M1 is connected to M (X124 or X132), the system is no longer electrically isolated.
