Installation Environment3.3
3.3.1 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 pBS2120, 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.
3.3.2 Environmental Requirements
Table 3-2 gives the base station’s environmental requirements with regards to
temperature, humidity, and voltage.
Table 3-2 Environmental Requirements of the Base Station

Range
Humidity
-40°C ～55°C
Relative humidity (no condensation)
5% ~ 95%
Personnel Requirements3.4
The installation personnel must master the basic safe operation knowledge, through the
training, and having the corresponding qualifications.
Grounding Protection3.5
CAUTION:
It is unlikely to happen but since the LTE eNodeB 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.
Grounding Notes:

pBS2120 Base Station Installation Guide
8
The ground wire adopts yellow-green wire that is no smaller than 16 mm².
Grounding principle: as near as possible.
The eNodeB 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.
Regulatory Compliance3.6
FCC Compliance
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that

Any Changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment
is operated in a commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the
interference at his own expense.
Warning
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 30 cm between the radiator & your body.
ISEDC Compliance
This device complies with Innovation, Science, and Economic Development
Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions: (1) This device may not

cause interference, and (2) This device must accept any interference, including i
nterference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d' Innovation, Science et
Développement
économique Canada applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions
suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi,
même si le brouillage est susceptible d'en compromettre le fonctionnement.
The antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 30 cm from all persons and must not be collocated or
operating in conjunction with any other antenna or transmitter, End-Users must

2. Drill four 12mm diameter and 80mm depth holes in the wall by following the
marked locations.
3. Check the up/down direction of the installation rack, and then fix the base
station to the wall using M8*80 expansion screws.
4. When install on wall, the U shape clamp is not needed.
5. Fix the base station on the bracket and adjust to proper angle.
Connect Cable4.3
4.3.1 Connect Ethernet Cable

12
open the wiring cavity.
2. Connect the Ethernet cable to ETH interface in the wiring cavity.
3. Lay Ethernet cable along the wire groove, and stretch out the wiring cavity from ETH
hole.
4. The other end of the Ethernet cable connects to the PoE power adaptor.
4.3.2 Connect Ground Cable
Make the grounding cable according the actual situation of the installation site.
The grounding screws of pBS2120 located on the bottom of the base station, as shown
in Figure 4-1.
Figure 4-1 Location of Grounding Screws
1. Unscrew the 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.
