ELEKTRA TuffTec 30, Руководство по установке

Страница: 21 / 104

In case of a significant sensor’s distance from
the switchboard, or bending of the protective
conduit, it is necessary to:
• install an additional sealed electric box “on
the way” to the board, or
• install the protective conduit with a twisted
pair screened control cable, min. 3-pair (e.g.
LIYCY-P 3x2x1.5)
– the sensor’s wire with the control cable is
to be connected with a heat shrink connect-
ing joint
Stage 4: Finishing surface
works
During execution of the asphalt surface, first
select the positioning place for the installation
tube, then – after the asphalt has been rolled and
it has cooled down – mount the tube. The space
between the tube and asphalt should be filled
with either concrete or asphalt poured cold, and
the tube should be levelled so that it will be posi-
tioned 5 mm below the level of the surface.
For the time of pouring and rolling the asphalt,
the place selected for the positioning of the sen-
sor should be filled with material which – after
the asphalt has cooled down – will be removed
(e.g. a wooden block 10x10x10 cm in size).
Note:
The section of the protective conduit to be laid
in asphalt should be made of a metal pipe, due
to high temperatures present while asphalting.
