BTS3902E WCDMA Installation Guide 9 Installing Cables Procedure Step 1 Determine the position for installing the ground clip on the cable based on the actual cable route. Step 2 Use a utility knife to strip the sheath off the FE/GE cable for about 32 mm to expose the shield layer, as shown in Figure 9-34. CAUTION Do not damage the shield layer when stripping the sheath off the cable.
BTS3902E WCDMA Installation Guide 9 Installing Cables CAUTION l Wrap the tape around the clip from bottom up, then from top down, and finally from bottom up. Do not cut the tape until all the three layers of the tape are already wrapped. When wrapping tape, be sure that each layer of tape overlaps more than 50% of the preceding layer. l The degree between the ground cable and the FE/GE cable is not greater than 15°. When the FE/GE cable is routed vertically, the ground cable must be routed downwards.
