2.4 Location & Environment
When determining where to place the eNB, you need to consider factors such as climate,
hydrology, geology, the possibility of earthquakes, reliable electric power, and transportation
access. Refer to the technical specifications in
Avoid locating the eNB in areas where there may be extreme temperatures, harmful gases,
unstable voltages, volatile vibrations, loud noises, flames, explosives, or electromagnetic
interference (e.g., large radar stations, transformer substations). Avoid areas that are prone to
impounded water, soaking, leakage, or condensation.
2.5 Grounding & Lightning Protection
You must protect the Nova-233 eNB, GPS, external antenna, and RJ-45 port against lightning.
The eNB has two ground screws which are located on the bottom of the unit. You must connect
the ground screws to a reliable outdoor grounding point (earth) using yellow-green ground
wire that is at least 16mm
In principle, always place the grounding as near as possible to the equipment. Ensure that the
connection of the grounding points and the ground bar are tight. Rustproof the terminals using
rust preventing paint, anti-oxidation coatings, grease, or similar solution.

2.6 Weatherproofing

To protect the connection points from weather and climate, clean each connection point
before installing cold shrink tubes, per the following (Figure 2–2).
1. Insert the cable into the cold shrink tube.
2. Tighten the connector.
3. Push the cold shrink tube to the top joint, and pull out the strip.
4. Ensure the cold shrink tube is tightly fitted with the connection.
