To form a line structure, two interfaces are internally bridged. See the figure below:

3.3.4 Configuration interface "Config"
A WAGO USB Communication Cable (Art.-Nr. 750-923) can be connected here.
To configure the power measurement module for visualizing measured values as the
power is measured and for firmware updates, an engineering PC with the Interface Con-
figuration Software is used.
Communication via the power measurement module and the PC is via the interface “Con-
fig” on the front side. This interface is designed as a 4-pin header used specifically for
WAGO communication solutions.
The operating system recognizes the communication cable as a virtual COM port.

3.3.5 Supply Connection "POWER"
An SELV with 24 VDC must be connected at the supply connection “POWER.”
The terminals are the Push-in CAGE CLAMP® design with pushers and have a test slot.
