4.2.2 Interfaces
The CPU has an integrated power supply:
n
The power supply has to be provided with DC 24V. For this serves the double DC 24V
slot, that is underneath the flap.
n
Via the power supply not only the internal electronic is provided with voltage, but by
means of the backplane bus also the connected modules.
n
The power supply is protected against polarity inversion and overcurrent.
n
The internal electronic is galvanically connected with the supply voltage.
