Places prone to have impounded water, soaking, leakage, or condensation, should also be avoided. Factors like climate, hydrology, geology, earthquake, electric power, and transportation should be taken into consideration in the construction process so that a proper location can be chosen to meet the communication engineering environmental requirements, as well as the technical requirements of network planning and communication equipment. 2.3.2 Environmental Requirements Table 2-2 gives the base stations environmental requirements with regards to temperature, humidity, and voltage. Table 2-2 Environmental Requirements Item Temperature Relative humidity

42V to 58V Typical value 25C 5% to 95%
48V 2.3.3 Space Requirements After the base station has installed, the enough space must be provided for operation and maintenance. And for heat dissipation and normal running of the base station, the space must be planed before installation, as shown in Figure 2-1. 8 Figure 2-1 Installation Space Requirement 2.4 Personnel Requirements The installation personnel must master the basic safe operation knowledge, through the training, and having the corresponding qualifications. 2.5 Against Lightening 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 install on the tower. The operator must prepare 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 mm. 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 9 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-233 G2 adopts 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 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 connect with the connection. 10 Nova-233 G2 (mBS1105) Outdoor LTE TDD Base Station Installation Guide 3.

Lay optical fibers along the wire groove, and stretch out the wiring cavity from OPT hole. hole. The redundant fiber should wind neatly. 3.6.5 Connect Ethernet Cable 1. Connect the Ethernet cable to ETH interface in the wiring cavity. 2. Lay Ethernet cable along the wire groove, and stretch out the wiring cavity from ETH 3.6.6 Connect Power Connector Because it is not sure that the distance between the installation site and the power supply device, the two ends of power adapter are bare terminal end. The operators need to make power cable according to the actual conditions on installation site, and assemble power plug and power terminal on two ends of power adapter. Strip 12mm insulating layer with wire stripper, which is used for connection to connector. It is recommended that the power cord length is kept below 100m (330 feet). The connection steps of power cable is as follows. 1. Assemble power plug. The power plug will be installed on the end of input direction. Refer to the identification on power plug, connect live wire, neutral wire, and ground wire to corresponding terminals separately, and tighten screws. 2. Assemble power terminal. The power terminal will be installed on the end of output direction. Refer to the following figure to connect live wire and neutral wire. 3. Connect the power cable to PWR interface in the wiring cavity. 4. The power cable lays along the lint slot, and stretch out the wiring cavity from PWR 5. The input of the power adaptor connects to the outlet. If the outlet is indoors, place the power adaptor indoors. hole. 16 If the outlet is outdoors, place the power adaptor in a water proof box. 6. After the cable connection is complete in the wiring cavity, tighten the screws on the cover to close the wiring cavity using M4 cross screwdriver. 3.6.7 Connect Ground Cable Make the grounding cable according the actual situation of the installation site. The Nova-233 G2 provides two grounding screws, which is located on the bottom of the base station, as shown in Figure 3-2. Figure 3-2 Location of Grounding Screws 1. Unscrew one grounding screw, connect one end of the grounding cable to the grounding screw, and fasten it again. 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 followings 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 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 17 that the antenna top falls within the 45 degrees safety angle towards the lightening rod, as shown in Figure 3-3. In principle, no lightening rod can be welded to pole (no metal object is allowed within 1m of the horizontal direction of the omnidirectional antennas), when installing the omnidirectional antennas. Instead, an independent lightening rod should be settled between the two poles, where the lightening rod must be high enough to keep all antennas under its protection cover. Figure 3-3 Omnidirectional Antenna Installation (1) In case is impossible to install an independent lightning rod due to environmental limitations, the installation method shown in Figure 3-4 can be used. Be aware that the pole supporting the lightening rod should be kept at least 1m away from the omnidirectional outdoor antennas. Figure 3-4 Omnidirectional Antenna Installation (2) 18 3.7.2 Install Directional Antennas 1. First, assemble the antennas, as shown in Figure 3-5. Figure 3-5 Assembling Procedure of Directional Antennas 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 Figure 3-6. Following the safety rules when working at these heights. Figure 3-6 Transportation the Antennas in the Height 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 Figure 3-7. 19 Figure 3-7 Directional Antenna Installation 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. 20 Nova-233 G2 (mBS1105) Outdoor LTE TDD Base Station Installation Guide 4.
