Issue 05 (2023-03-31)
shows the label on the trunk cable between the device and the DDF:
For equipment room installed with supports and ESD protection floor, cables
can be arranged in downward mode. That is, all cables can be routed through
the interlayer of the floor or the cable trough. If the overhead cabling mode is
adopted, cable tray is required above the cabinet for holding cables.
The specifications and cross-sectional area of the cable, and the route and
position for cabling should be designed beforehand.
All cables should be arranged neatly, with their sheaths remaining intact.
Communication cables, such as alarm cables, network cables and clock cables,
should be arranged separately with the power cable and optical fibers.
Turnings of the cable should be smooth, with the bend radius reaching 60mm
or above.
Any damage to the insulation layer of the conducting line is not allowed.
The cable arrangement should take the future maintenance and capacity
expansion into consideration.
