Installation Environment2.3
2.3.1 Locational Requirements
Environments with high-temperatures, harmful gases, unstable voltages, volatile
vibrations, loud noises, flames, explosives, and electromagnetic interference (large radar
stations, transmitting stations, transformer substations) are not suitable for the operation
of Nova-233 G2, and thus should be avoided.
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 station’s environmental requirements with regards to
temperature, humidity, and voltage.

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.

Figure 2-1 Installation Space Requirement
Personnel Requirements2.4
The installation personnel must master the basic safe operation knowledge, through the
training, and having the corresponding qualifications.
Against Lightening and Grounding Protection2.5
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 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

10
reliable. Rustproofing the terminals is required. This can be done with rust
preventing paint, anti-oxidation coatings, grease, and so on.
Weatherproof Protection2.6
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.

3.Base Station Installation
Unpacking3.1
Before opening the box, make sure the package is in good condition, undamaged and
not wet. During the unpacking, avoid potential damaging impacts from hits or excessive
force.
Once unpacked, check whether the quantity are consistent with the packing list.
Installation Procedure3.2
The installation procedure of Nova-233 G2 is given in Figure 3-1.
Figure 3-1 Installation Procedure of Nova-233 G2
Install GPS Antenna3.3
Installation requirements on the GPS antenna:
No major blocking from buildings in the vicinity. Keep the rooftop buildings a
distance away from the GPS. Make sure the space atop within 90 degrees (at least
45 degrees) is not blocked by any buildings.
Avoid installing the GPS in the vicinity of any other transmitting and receiving

12
devices. Avoid interference from other transmitting antennas to the GPS antennas.
Should be installed within 45 degrees to the lightning rod.
The GPS has been assembled before packing, the only installation step is to fix the GPS
mounting bracket on the base station using the M4 x 14 screws.
Install on Pole3.4
Required diameter of the pole: 40mm ~ 100mm.
Suggest the installation height higher than 120cm, and the installation space
requirements meet the requirements in “2.3.3 Space Requirements”.
The mount bracket has been assembled before packing.
1. Unscrew the four screws of the assembled bracket and slide the two omegas to the
left as the following figure, and then turn the two omegas up or down.
2. Make sure the base station’s installation height, fit the thread rod of the assembled
bracket to the pole, and then turn the two omegas to proper position as the following
figure, and slide the two omegas to the right, and then fasten the four screws.

13
3. As the following figure, hung the two pins on the base station bracket to the
installation bracket, push the base station until the hook block to the base station
bracket.
4. Tighten two screws on the top of the bracket using cross screwdriver to complete
the installation.

14
Install on Wall3.5
The wall must bear four times of the base station’s weight.
1. Take apart the assembled installation bracket kit to get the installation bracket.
2. Fit the bracket on the wall, and mark the drilling locations.
Caution:
The arrow of the installation bracket must be upward.
3. Drill two 10mm diameter and 70mm depth holes in the wall on the marked
locations, and insert the expansion pipes.
4. Check the up/down direction of the installation rack, and then fix base station
to the wall with M8 x 80 expansion bolts.
5. Refer to the installation steps on pole, fix base station on wall.
