2.3.1 Locational Requirements
Environments with high-temperature, harmful gases, unstable voltage, big vibration, high
noise or exposed to flammable, explosive, electromagnetic interference (large radar
station, transmitting station, transformer substation) are not suitable for the operation of
BRU3510, and thus should be avoided. Places prone to have impounded water, soaking,
leakage, or condensation, should also be avoided.
In the construction process, factors like climate, hydrology, geology, earthquake, electric
power, and transportation should be taken into consideration 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.
2.3.2 Environmental Requirements

2.3.3 Power Requirements
BRU3510 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.
