Tab. 10-1: Pin assignment of the power connector XD1
In the power connector, the contact a1 is bridged with a2 and the
contact b1 is bridged with b2. The control is set up to connect to a
UPS in future variants. Thus, 2A is labeled with "UPS". However, a
UPS can only be used without bridges when a respective variant and
a specific power connector are used.
10.7.3 24 V voltage supply
The voltage of 24 V can be supplied with or without electrical isolation.
Setup without electrical isolation
An easy connection method is the setup without an electrical isolation between
the internal logic and the peripheral supply.
In this case, a power supply unit is sufficient to supply the control.
