Fig. 10-15: Setup without electrical isolation
Control does not start in case of reverse input voltage
The feeding of 24 V at the XD1 connector is protected against polari-
ty reversal. A polarity reversal of U
age the device. However, the control does not start and the U
is not on.
Reference conductor connected to the protective conductor and set up with
electrical isolation
Provide electrical isolation between the logic of the central processing unit and
the I/O interfaces of the peripheral component groups according to DIN EN
60204-1. Accordingly, the voltage U
trically isolated from the supply voltage for the I/O modules.
