2.3.1 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 Nova-243, 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.

2.3.3 Power Requirements
Nova-243 TDD base station adopts -48V DC power supply. For the safety and reliability of
device, we have the following suggestions.
Remote DC power supply, in general, AC power supply is 100V ~ 270V, the distance
of AC power supply to the device is less than 30 meters.
If the static exceeds a certain range, it will lead to great damage to the circuit and the
whole device.
