2.5 Against Lightning and Grounding Protection

CAUTION:
It is unlikely to happen but since the LTE base station is very sophisticated equipment so we would recommend you to test it on the ground to make sure everything is functioning before installation on the tower.

The operator must prepare an external against lightning protector to protect the GPS, external antenna, and RJ-45 port.
Grounding Notes:

• The ground wire adopts yellow-green wire that is no smaller than 16 mm².
• Grounding principle: as near as possible.
• The base station connects to the reliable outdoor grounding point (earth) through one ground screw.
• The connection of the grounding points and the ground bar need to be tight and reliable. Rustproofing the terminals is required. This can be done with rust-preventing paint, anti-oxidation coatings, grease, and so on.

2.6 Weatherproof Protection

The Nova-436Q adopts a cold shrink tube for weatherproof protection. Before installing the cold shrink tube, clean up the interface first. The weatherproof protection steps are as follows:

1. Insert the cable into cold shrink tube.
2. Tighten the connector.
3. Push the cold shrink tube to the top joint and pull out the strip.
4. Check whether the cold shrink tube tight connects with the connection.

to make the power cables according to the actual conditions on the installation site and assemble the power plug and power terminal on two ends of the power adapter.
Strip 12mm insulating layer with wire stripper, which is used for connection to the connector. It is recommended that the power cord length is kept below 100m (330 feet).

The connection steps of the power cable is as follows.

1. Assemble the power plug.
   The power plug will be installed at the end of the input direction. Refer to the identification on the power plug, connect live wire, a neutral wire, and ground wire to corresponding terminals separately, and tighten screws.

2. Assemble power terminal.
   The power terminal will be installed at the end of the output direction. Refer to the following figure to connect a live wire and a neutral wire.

3. Connect the power cable to the PWR interface in the wiring cavity.

4. The power cable lays along with the lint slot and stretches out the wiring cavity from the PWR hole.

5. The input of the power adaptor connects to the outlet.
   • If the outlet is indoors, place the power adaptor indoors.
   •  If the outlet is outdoors, place the power adaptor in a waterproof box.

2. The other end of the ground cable needs to connect to a good grounding point.

3.7 Install Antenna Feeder System
There are two kinds of outdoor antennas, omnidirectional outdoor antennas and directional outdoor antennas, whose installation will be introduced in the following, respectively.

3.7.1 Install Omnidirectional Antennas
One should pay attention to the following while installing the omnidirectional outdoor antenna:

• The diameter of the pole for omnidirectional outdoor antennas is required to be 35mm ~ 50mm. A typical case is to use the 50mm-diameter round-steel-made pole (with details depending on the specific antenna type).
• Make sure that the top of the pole and the clamp beneath the antenna are at the same level, after installing the omnidirectional outdoor antenna on the pole.
• Make sure that the antenna is high enough to meet the coverage requirement, and that the antenna top falls within the 45 degrees safety angle towards the lightning rod, as shown in Figures 3-4. In principle, no lightning rod can be welded to a pole (no metal object is allowed within 1m of the horizontal direction of the omnidirectional antennas), when installing the omnidirectional antennas. Instead, an independent lightning rod should be settled between the two poles, where the lightning rod must be high enough to keep all antennas under its protective cover.

In case is impossible to install an independent lightning rod due to environmental limitations, the installation method shown in Figures 3-5 can be used. Be aware that the pole supporting the lightning rod should be kept at least 1m away from the omnidirectional outdoor antennas.

3.7.2 Install Directional Antennas

1. First, assemble the antennas, as shown in Figure 3-6.
   

2. To install it on the iron tower, use a pulley to transport the antenna assembled to the platform on the iron tower, as shown in Figures 3-7. Following the safety rules when
   working at these heights.
   

3. Fix the pole vertically to the ground or concrete pillars on the rooftop using expansion screws, and fasten it with steel wires. Then, mount the directional outdoor antenna onto the pole using the installation rack, as shown in Figures 3-8.
   

4. When the base station has been installed in a proper position, connect all the cables and wires.

5. Run tests, then seal and weatherproof all the connections after the testing has successfully completed. Refer to 2.6 Weatherproof Protection.
