14Grounding cable requirement: The grounding cable must connect to the grounding point. The grounding cable must be separated from the signal cables, of enough distance toavoid signal interference.3.4.2 Connect GPS Antenna Cable1. Insert the GPS jumper into a cold shrink tube.2. Connect one end of the GPS jumper to the GPS antenna.3. Push the cold shrink tube to the top joint, and pull out the strip.4. Connect the other end of the GPS jumper to the GPS interface on the eNB, which alsoneeds weatherproof protection.3.4.3 Connect RF Cable1. Open the dust caps of the ANT0, ANT1, ANT2, and ANT3 interfaces.2. Insert the RF cables into cold shrink tubes.3. Connect one end of the 2 RF cables to the ANT0, ANT1, ANT2, and ANT3 interfaces onthe eNB, and tighten them with a wrench.NOTE: When the Nova-436Q is operating in dual carrier (split) mode (futuresoftware upgrade), Cell 1 uses ANT2 and ANT3 and Cell 2 uses ANT0 and ANT1.4. Push the cold shrink tube to the top joint, and pull out the strip.5. Connect the other end of the RF cables to the external antennas, which also needweatherproof protection.3.4.4 Connect WAN Interface Cable1. Unscrew the 3 screws on the cover of the eNB’s wiring cavity using an M4 crossscrewdriver. Open the wiring cavity.2. Connect the cable to the copper or optical interface in the wiring cavity.3. Lay the cable along the wire groove, and stretch it out of the wiring cavity.3.4.5 Connect Ethernet Cable1. Connect the Ethernet cable to the ETH interface in the wiring cavity.2. Lay the Ethernet cable along the wire groove, and stretch it out of the wiring cavity.3.4.6 Connect Power ConnectorSince the length of cable needed for power varies from site to site, the two ends of the poweradaptor are bare terminal ends. You will need to make the power cable according to the actualmeasurements of the installation site, and assemble the power plug and power terminal onthe two ends of the power adaptor.Strip .47in/12mm insulating layer with a wire stripper. The power cord length should be keptbelow 330 ft/100m. The connection steps for the power cable are as follows.
