7.2 Cabling
7.2.1 Safety Instructions
Warning
Risk of electric shock.
► Do not connect the unit to the power supply during installation.
Connection to the power supply must be performed by a trained, quali ed and author-
ised specialist.
Notice
Risk of damage to the cables!
There is a risk of malfunctions if cables are damaged because they are bent more than the
minimum bend radius permits, or if cable fasteners are overtightened. Such damage is not
evident from outside and will lead to signal errors.
Comply with the K-BOW Cabling Guidelines
when laying (bending) and xing optical bre
and other cables.
● When doing the work described in this chapter, comply with the cabling rules in the
document K-BOW Cabling Guidelines.
● Perform the cabling strictly as described in the document K-BOW Setup Manual and in
the planning document for the system.
● Throughout all cabling work, comply with the minimum bending radii
1)
for the cables;
this is particularly critical for bre optic cables and hybrid cables.
● Fasten the cables as follows:
– If possible, use Velcro straps
2)
to secure bre optic cables, hybrid cables, coax
cables
3)
and other sensitive cables.
– If you only have plastic cable ties: Tighten the cable ties only to such an extent that
the cables are by no means compressed, deformed or squeezed.
– If possible, only use plastic cable ties for the power supply cables laid vertically
from the power supply units to the PSUs. Tighten cable ties by hand without too
much force
4)
and trim the free ends.
● Label the cables as soon as they are laid
5)
and document the label text
6)
.
● The illustrations in this chapter show only basic examples for the cabling between
components.
● For more information about the cabling of the remote units, see the document Instal-
lation Manual (K-BOW Platform 2) and the installation instructions for the remote units.
1)
The permissible bending radii can be found in the cable data sheets.
2)
Velcro straps are less likely to deform the cables and are more exible to handle than cable ties.
3)
Coax cables from the base station to the load unit.
4)
Do not use any tools to tighten the ties. This is particularly critical for bre optic and hybrid cables.
