2.3 Location and Environment
The Nova430e can be installed on a pole or a wall. For the best signal coverage, place the eNB in
an unobstructed location. In addition to network planning, when determining where to place the
eNB, you need to consider the best location for signal coverage. 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 prone to impounded water, soaking, leakage, or
condensation. Environmental specifications are shown in Table 2-5.

2.4 Grounding and Lightning Protection
You must protect the eNB, antenna, and GPS against lightning. All Nova eNBs have a floating ground
on the power system. Following are guidelines concerning grounding.
The yellow-green ground wire must be at least 6 AWG (10 mm
2
) diameter.
Always place the grounding as near as possible to the equipment.
Connect to a reliable outdoor grounding point (earth) using one ground screw.
The connection of the grounding points and ground bar needs to be tight and reliable.
Rustproofing the terminals, e.g., with antioxidant coating or grease, is required.
