Nova430i Outdoor 4x250mW Two-Carrier TDD eNodeB Installation Guide
6. The grounding wire shall be connected to the integrated grounding bar of the building. If it is
impossible to connect to the integrated grounding bar of the building, the appropriate grounding
point can be selected according to the integrated grounding situation of the indoor building. The
selection of grounding point must be higher than the grounding grid, and the feeder grounding
shall be towards the downward direction of the feeder, never upward.
7. The grounding electrode of the self-built grounding grid for the outdoor antenna of the tunnel
must meet the design requirements. The buried depth of the grounding electrode and the welding
quality of the flat iron meet the specification requirements. In principle, the buried depth of the
grounding electrode shall not be less than 27.5 in (0.7 m). The non-self-built grounding network
shall be connected to the grounding network of the owner.
8. The eNB grounding, power adapter grounding, distribution box grounding and feeder grounding
must be connected to the grounding bar independently, and the grounding bar must have a path
from the lead to the earth.
3.5 Maintenance Chamber Waterproofing
Once the installation is complete, you must close the maintenance chamber of the equipment and
waterproof the chamber.
Put the Ethernet cable on the wire, and seal the wire diameter 0.3 in
Before installing the eNB at its final destination, perform the steps in
The eNB is ready for installation at the cell site after successful testing. Seal and weatherproof all the
connection points, and rustproof where needed.
3.6 Power on to Check LED Status
WARNING:
Ensure the antenna is connected before powering up the eNB. The wireless signal
transmission power can cause bodily injury and damage to the eNB and RF power amplifier
devices.
After the Nova430i power is turned on, check that the LED indicators are lighting as expected: Power is
steady green, cell activated is slow flash green, and there are no alarms (Figure 3-12) per Table 2-3.
