4.
All the cable cannot have break-down and terminal in the
middle;
5.
Cables should be straight in the hallways and turning;
6.
Cable should be straight in the groove, and cannot beyond the
groove in case of holding back the inlet and outlet holes.
Cables should be banded and fixed when they are out of the
groove;
7.
User cable should be separated from the power lines. Cables,
power lines and grounding lines cannot be overlapped and
mixed when they are in the same groove road. When cable is
too long, it cannot hold down other cable, but structure in the
middle of alignment rack;
8.
Pigtail cannot be tied and swerved as less as possible.
Swerving radius cannot be too small (small swerving causes
terrible loss of link). Its banding should be moderate, not too
tight, and should be separated from other cables;
9.
It should have corresponding simple signal at both sides of the
cable for maintaining.
