Configuration guidelines | Selecting the cable carrier
1.3 Defining the cable carrier size The number and diameter of the cables to be installed play a major role here. Very often, the dimensions of the installation space for using a cable carrier are very limited. Both these prerequisites therefore have to be balanced. The basic data of the cables to be installed are required for the further configuration of the cable carrier:
■ ■ Type (cable or hose) ■ ■ Outer diameter (d) ■ ■ Cable weight incl. media (q z )
■ ■ Minimum bending radius of cables/hoses (KR min )
Please select a cable carrier with a sufficient inner height (see page 36). Adequate space on the side for placing the cables should also be planned for the initial configuration. They have to be arranged freely in the cross section of the cable carrier. The following minimum values for the required space apply: Cables: 1.1 x d (add 10% to the O.D. of each cable to insure adequate free space) Hoses: 1.2 x d (Add 20% to the O.D. of each hose to insure adequate free space) More information for installing cables can be found in chapter Placement guidelines on page 70.
The first draft for a so-called crossbar pattern can then look as follows, for example:

It is possible that the cable carrier becomes too wide with regard to the permitted installation dimension. In this case, a larger cable carrier can be used in combination with one of the divider systems. The placement could then look as follows, for example: For the installation of cables in the cable carrier, please also take the selected installation option into account (see page 74) which can have additional impli-
cations for loading the cable carrier. The different available crossbar options (e.g. hole crossbar, tube crossbar) also allow different options to suit the application. This initial draft still has to be verified with regard to the further configuration of the cable carrier in the following (e.g. unsup- ported use).
