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-243, 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 on temperature, humidity,
and voltage.

2.3.3 Power Requirements
Nova-243 TDD base station adopts -48V DC power supply. For the safety and reliability of
device, we have the following suggestions.
Remote DC power supply, in general, AC power supply is 100V ~ 270V, the distance
of AC power supply to the device is less than 30 meters.
If the static exceeds a certain range, it will lead to great damage to the circuit and the
whole device.
Personnel Requirements2.4
The installation personnel must master the basic safe operation knowledge, through the

Nova-243 Outdoor LTE TDD Base Station Installation Guide
8
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
reliable. Rustproofing the terminals is required. This can be done with rust preventing
paint, anti-oxidation coatings, grease, etc.
Weatherproof Protection2.6
The Nova-243 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.Install the Base Station
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-243 is given in Figure 3-1.
Figure 3-1 Installation Procedure of Nova-243
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
devices. Avoid interference from other transmitting antennas to the GPS antennas.
Should be installed within 45 degrees to the lightning rod.

Nova-243 Outdoor LTE TDD Base Station Installation Guide

The GPS cable should be as shorter as possible to reduce the influence to signal
strength.
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, as shown in Figure 3-2.
Figure 3-2 Install the GPS Antenna
Install on Pole3.4
Required diameter of the pole: 30mm ~ 100mm and suggest the installation height
higher than 120cm.
The mount bracket has been assembled before packing, as shown in Figure 3-3. The
installation personnel only need to fix the assembled base station on the pole.
Figure 3-3 Pre-assembled bracket
1. Take down the two outer omegas.

2. Make sure the base station’s installation height, fit the thread rod of the assembled
bracket to the pole, and then pass the two omegas through the threaded rods, and
fasten the four flat gaskets, four spring gaskets, and four nuts.
3. Mount the base station vertically on the bracket and tighten M6 screw on the top of
bracket using cross screwdriver to complete the installation.

Install on Wall3.5
The wall must bear four times of the base station’s weight.
1. Take apart the assembled bracket.
2. Install three mounting hooks on the base station with M6 x 16 screws.
3. Fit the base station with hooks on the wall, and mark the drilling locations.

4. Drill three 12mm diameter holes in the wall on the marked locations, and
insert the expansion pipes.
5. Fix base station to the wall with M8 x 80 expansion bolts.
Connect Cable3.6
3.6.1 Requirement for Cable Laying
General requirements:
Bending radius requirement of feeder cable: 7/8” > 250mm, 4/5” > 380mm.
Bending radius requirement of jumper cable: 1/4” > 35mm，1/2” (super soft) > 50mm，
1/2”(ordinary)>127mm.
Bending radius requirement of power cable and grounding cable: > tripled of the
diameter of cable.
Binding the cables according the type of the cable, the intertwining and crossing is
forbidden.
The label should be paste after the cable laying.
Grounding laying requirement:
The grounding cable must connect to the grounding point.
The grounding cable must be separate with the signal cables, remaining a certain
distance to avoid the interruption of signal.

3.6.2 Connect GPS Antenna
1. Insert GPS jumper into 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 GPS interface of the base station,
which also need weatherproof protection.
3.6.3 Connect RF Cable
1. Open the dust cap of ANT0 and ANT1 interface.
2. Insert RF cables into cold shrink tube.
3. Connect one end of the two RF cables to ANT0 and ANT1 interface of the base
station and tighten them with wrench.
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 antenna, which also need
weatherproof protection.
3.6.4 Connect Ethernet Cable
1. Connect the Ethernet cable to ETH0 interface in the wiring cavity.
2. Lay Ethernet cable along the wire groove, and stretch out the wiring cavity from
ETH0 hole.
3.6.5 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
