9. Appendix C Cabling Recommendations in Installation
❖ When cables need to be bent, you should first bundle them up. However, the buckle cannot
be bundled within the bend area. Otherwise, considerable stress may be generated in cables,
breaking cable cores. As shown in Figure C-3.
Figure C-3 Bundling up cables (3)
❖ Cables not to be assembled or remaining parts of cables should be folded and placed in a
proper position of the cabinet or cabling slot. The proper position indicates a position that
will not affect device running or cause device damage or cable damage during
commissioning.
❖ 220V and -48V power cords cannot be bundled on the guide rails of moving parts.
❖ The power cables connecting moving parts such as door grounding wires should be reserved
with some access after assembled to avoid suffering tension or stress. When the moving part
reaches the installation position, the remaining part should not touch heat sources, sharp
corners, or sharp edges. If heat sources cannot be avoided, high-temperature cables should
be used.
❖ When using screw threads to fasten cable terminals, the bolt or screw must be tightly
fastened, and anti-loosening measures should be taken, as shown in Figure C-4.
