ZXSDR R8964 User Manual 5.2 Replacing PE Cable Prerequisite Make sure that the length of the new PE cable is the same as that of the old grounding cable. Make sure that services are not affected during the replacement. Context The basic grounding net project and tower of the grounding system, the grounding project of the building, and connection points of the indoor/outdoor copper ground bar are constructed by customers.
Chapter 5 Product Maintenance l Bend the new optical fiber at the turning. Steps 1. After the old optical fiber is removed, put the protective cap on the optical port so as to avoid contaminating the optical port. 2. Cut off the cable tie of the old optical fiber, remove the old optical fiber, and then put the fiber to the moisture-proof bag. 3. Lay the new optical fiber the same path with the old one, fasten fiber connector, and then attach label on the new optical fiber. 4.
