Electrical isolation concept
All control terminals are designed as safety extralow voltage/protective ex
tralow voltage (SELV/PELV) circuits and must only be operated with such
SELV/PELV voltages, as per the relevant specification. This provides reli
able protection against electric shock on the control side.
The 24 V power supply necessary for the PELV circuit is provided by the
supply module D3DU 3xx/x via the busbars 24 V DC / GND. The following
overview shows the potential supplies for the individual terminals in detail.
This concept also delivers higher operational safety and reliability of the axis
modules and the controller.
