Conductor in supporting tube (length of 3.2 m) installed in a tripod
Isolated supporting tubes with a diameter of 50 mm can be connected via the adapter attached to the
tripod. The adapter allows to adjust supporting tubes up to an angle of 10° to compensate roof inclinations.
Depending on the alignment of the inclination angle, the supporting tube (aluminium pipe, Ø 50 mm)
is inserted into the adapter and screwed into place with four M10 locking screws. In addition, the four
hexagon nuts have to be tightened to the adapter. The specified tightening torques have to be observed
(see Figure 11, page 14). The supporting tube with tripod (

II).
In order to keep the minimum bending radius of the

of 200 mm / 230 mm, the tripod
must be installed in an elevated position. The following steps have to be observed when installing the
tripod:
■
Wedge the pre-mounted bracing into the lowest concrete base (Figure 10a).
■
Mount the middle concrete base (first drive out the cover) (Figure 10b).
■
Install the tripod (Figure 10c).
■
Wedge the top concrete base (first drive out the cover) (Figure 10d).
