3.6 Location and 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.
3.7 Spacing
When determining the location for the eNB, consider what space is required for ongoing
operation and maintenance. Allow space for heat dissipation and normal operating limits, as
specified in
Appendix
Figure 3-2: Spacing Requirements
3.8 Power
The Nova-243 eNB uses a -48V DC power supply. For the safety and reliability of the device,
observe the following recommendations:
A remote DC power supply is generally recommended. An AC power supply of 100V
•
to 240V can be used if the distance to the device is less than 98 feet (30 meters).
Excessive static can damage the circuit and the whole device. Take normal precautions
•
for electrical discharge.
