1. The specification, routing and location of the cable should conform to the design regulations. The cable arrangement must be neat and beautiful, and the outer skin should not be damaged. 2. The contacts and solder joints are reliable, and the connectors are firm to ensure the effective transmission of signals. Try to use the entire length of wire to avoid the transfer; if the actual length is longer than the total length of the cable, you should ensure that the multi-segment cable is indirect and reliable. 3, the cable should be numbered, the label of the cable head should be correct and complete, the writing is clear, not easy to erase. The number should be consistent with the drawing. The number should be able to find the name, specification and point of the cable from the drawing. 4. Wiring should make full use of the local trenches, bridges and pipes to simplify wiring. The cloth line is not recommended. If it is not a cloth line, it should be hidden and beautiful. The maximum space should be reserved for the original space to facilitate the installation of other equipment in the future. It is best to use PVC decorative trunking for the wall l. The grounding or the wiring near the equipment should use the appropriate trunking or conduit to ensure safety and reliability. 5. The cables laid on the trenches and bridges must be bundled. The cables after the bundles should be close together. The appearance is straight and tidy, the spacing of the buckles is even and tight, and it is as close as possible to the style of the original route; it is laid under the raised floor. And the wiring of the ceiling L should be placed in the groove (tube) of the flame retardant material, as straight as possible, with less crossover. 6. The wire materials used in the security monitoring system should use flame retardant materials; insulation should be selected according to the site environmental conditions. PI-il, anti-interference-IIIii, anti-corrosion performance, etc. are all suitable for the cable; for signal lines susceptible to electromagnetic interference, shielded wires should be used. Pay attention to the correct grounding of the shielding layer during installation. 7. The signal line and power line should be separated and placed; the signal line should be as far away as possible from equipment or cables that are prone to electromagnetic interference. 8. When the outdoor overhead line is used, the necessary lightning protection measures should be taken at the equipment end; be sure to ensure good grounding when installing the lightning arrester.
