Status of the electron-
ics power supply
After switching on the Cube20S system, the RUN or MF LED lights up on ev-
ery module.
If the total current for the electronics supply exceeds 3 A, the LEDs are
no longer activated.
In this case, plug in the power module, art. no. 57131, between the expan-
sion modules.
NOTE
To guarantee power supply, the power modules can be used in any combina-
tion.
7.8.1
Power module art. no. 57130
Use the power module art. no. 57130:
If 10 A is no longer sufficient for the power supply.
If you want to have groups of different voltages.

1
24 V DC for power supply of I/O level (max. 10 A)
2
24 V DC for electronics supply, bus node and I/O level
7.8.2
Power module art. no. 57131
Using power module Art.-No. 57131:
If 3 A are not enough for the electronics supply on the backplane bus.
If you want to have groups of different potentials.
In addition, you will get a new voltage group for 24 V DC power supply with
max. 4 A.
