Example of Voltage Drop per Wire with a Current of 8 A on the WAGO 4 × 1.5 mm²
Supply Cable
U = 2 × 8 A × 13.7 Ω/km = 219.2 V/km
This corresponds to a voltage drop of 2.19 V per 10 m of cable length.
Example of Voltage Drop per Wire with a Current of 16 A on the WAGO 4 × 2.5 mm²
Supply Cable
U = 2 × 16 A × 8.22 Ω/km = 263 V/km
This corresponds to a voltage drop of 4.38 V per 10 m of cable length.
If the resistance of the cable used is not known, it can be calculated approximately with
the following formula:
R = l / (K × A)

9.3 Connecting Cables

WAGO recommends using 765 Series connecting cables, pluggable connectors and ac-
cessories for 756 Series products, which have been tailored specifically to the WAGO I/O
System Field.
The tightening torques given in section
pluggable connectors of the connecting cables.

9.4 Connecting Fieldbus

To establish a connection to an IO controller, connect the product to a network with a
transmission rate of 100 Mbit/s in full duplex operation.
You can find the connection assignment for the ETHERNET ports in section
NET Interfaces
If you do not use a pre-assembled ETHERNET cable, a shielded M12 plug with protec-
tion type IP 67 should be connected to it.
