Figure 4-9 Structure of the Festoon Cable
Festoon Cable 6XV1 830-3GH10
The festoon cable 6XV1 830-3GH10 complies with the specification EN 50170,
cable type A, with stranded copper cores (approximately 24 gauge - 19/36) apart
from the higher loop resistance.
This difference means a reduced segment length; refer to the table in Chapter 3
“Notes on Configuration”.
With its flexible structure, the festoon cable 6XV1830-3GH10 can be used in
festoons with large and small cable loops. The cable carries its own weight but is
not suitable for tensile stress > 80 N.
The outer sheath has the identification “SIMATIC NET PROFIBUS RS-485
Festoon Cable 6XV1830-3GH10 * (UL) CMX 75
°
C (SHIELDED) AWG 24” printed
on it along with meter markings.
To help to avoid twisting the cable during installation, the outer sheath has a line
printed along its full length.
If screw terminals are used, the stranded cores must be fitted with wire-end
ferrules (0.25 mm
2
complying with DIN 46228).
The bus connector 6ES7 972-0BA30-0XA0 cannot be connected.
The cable is not suitable for use of the FastConnect (FC) stripping tool.
