Trailing Cable 6XV1 830-3EH10

The trailing cable 6XV1 830-3EH10 corresponds to the specification EN 50170 Cable Type A, with stranded copper cores (approximately 24 gauge - 19/36) with the exception of the higher loop resistance.

This difference means a reduced segment length; refer to the tables in Chapter 3 “Notes on Configuration”.

In contrast to the standard LAN cable, the cores of the trailing cable are of stranded copper. In conjunction with the special combination of braid shield, foil shield, and the sheath material of polyurethane, the cable is extremely flexible while retaining highly constant electrical characteristics.

If you connect to screw terminals, the stranded cores must be fitted with wire-end ferrules (0.25 mm2 complying with DIN 46228).

The bus connector 6ES7 972-0BA30-0XA0 cannot be connected.

To help to avoid twisting the cable during installation, the outer sheath has a line printed along its full length.

The structure of the cable allows the use of the FastConnect (FC) stripping tool for fast stripping of the outer sheath (see Section 4.2.3).
