![RRU3260 Installation Guide 9 Installing RU Cables Issue 05 (2014-06-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 82 Cables must be routed away from heat sources, or heat-insulation materials are added between cables and heat sources. Sufficient slack (recommended for about 0.1 m [0.33 ft]) is provided in cables at turns or the position close to a device, facilitating cable and device maintenance. Indoor Cabling Requirements Cables are routed indoors through the feeder window. Drip loops must be made outside the feeder window, and the requirements for the minimum bending radius are met. When cables are routed indoors, engineers are required indoors for cooperation. The feeder window must be waterproofed. Outdoor Cabling Requirements Cables routed outdoors must be led through a pipe when they may be damaged. AC power cables, transmission cables, and cables buried in the ground must be protected. If cables at the cabinet bottom need to be routed through a pipe along the ground, lead the pipe into the cabinet base for about 30 mm (1.18 in.) to 50 mm (1.97 in.), not into the cabinet. Block the pipe with waterproof tape or silicon gel, and secure the pipe to the cable hole at the cabinet bottom with metal piece. If cables at the cabinet bottom need to be routed through a pipe along the metal cable trough, do not lead the pipe into the cabinet base. The cable trough must be sealed and routed through the cable hole at the cabinet bottom. When routing RU cables, ensure that the highest positions of the routes of all RU cables (except RF cables and AISG cables) must be lower than the bottom of the RU. Cables are secured with cable clips. Cables are routed neatly along the specified cabling direction and secured with cable clips. The positions for cable clips are determined onsite. For example, the cable clips for the 7/8" feeder are installed at the spacing of 1.5 m (4.92 ft) to 2 m (6.56 ft) in the same direction, and the cable clips for the power cables are installed at the spacing of 1.5 m (4.92 ft) to 2 m (6.56 ft) in the same direction. Cable clips must be vertical with cables, and the cables in a cable clip must be parallel. After routing cables neatly and correctly, tighten the screws on cable clips. Secure cables on the cable tray, as shown in Figure 9-1.](https://usermanual.wiki/Huawei-Technologies/RU3260.User-Manual-II/User-Guide-2409715-Page-90.png)
