Hardware Installation Guide
○ Metal holes through which cables pass should have smooth, rounding surfaces, or have insulating
bushings.
○ Select the appropriate buckle to bind cables. Do not tie two or more buckles together for binding.
○
After tying the cables with buckle, cut off the excess part. The incision should be smooth and neat, and
no sharp corner exists, as shown in
Figure 7-5 Cable bundling diagram (2)
○ When the cables need to be bent, bind the cables before binding. However, the buckle cannot be bound
in the curved part; otherwise, a large stress is generated on the cables and breaks the cable core, as
shown in
Figure 7-6 Cable bundling diagram (3)
○
For the cables that do not need to be assembled or are too long, fold and tie them at the appropriate
position in the cabinet or cable trough. The proper position refers to the position that will not affect the
operating of the device to cause device or cable damage during commissioning.
○ The 220 V and -48 V power cords cannot be bound on the guide rails of moving parts.
○
For the power cord connected to the movable parts, such as the door ground wire, an extra section
should be reserved to avoid stress on the cable. When the moving parts arrive at the installation position,
the extra section of cable will not touch heat sources, sharp corners, or sharp edges. If the heat sources
cannot be avoided, heat-resisting cables must be used.
