6.4 Fixation and Protection of Connecting Cables
6.4.1 Cable Fixation
In order to prevent loosening of the copper nose, causing poor contact, or increasing
contact resistance leading to fever or even fire, it is necessary to ensure that the screw
fastening the terminal meets the torque requirements listed in Table 6-4:

6.4.2 Cable Protection
The protection of cables includes communication cables and power cables. The protective
methods are as follows:
Protection of communication cable: Because communication cable is thin, it is easy to
break or fall off from the terminal during construction. Therefore, it is suggested that the
power circuit should be connected first, and then the connection should be made. When
connecting, the cable should be grooved as far as possible. Where there is no groove, the
cable should be fastened with tie-in belt. When traveling, the development of thermal
elements and strong electric field circuit cables should be avoided.
Protection of power cables: Therefore, the scratch and breakage of cable insulation skin
should be avoided when installing connection, because this may lead to short circuit. Power
cables must also be properly fixed.
6.5 Remove Switch Baffle And Lower Panel
