2.6.2 Power supply arrangement – formation of power zones
2-18
The modular power supply arrangement of the CPX terminal
facilitates the formation of power zones.
Observe the following:
– The CMIX connects the internal contact rails 0 V

This means that the operating voltage for the electronics/

At the module position of the CMIX, the same potential

electronics/sensors (V
The CMIX always connects the 0 V supply for the elec-
tronics with the 0 V supply for the valves. This must be
noted when a CPX-GE-EV-V interlinking block is located to
the left of the CMIX because this can remove an intentional
voltage isolation.
Basic information on the power supply arrangement of the
CPX terminal can be found in the CPX system manual.
