Operational Specifications
Operational Humidity
0.03 g/ m3 and 30 g/ m3 of absolute humidity
Operational Temperature Range
−40 to +55 °C; –40 to 131 °F (with solar radiation, without sun-shade)
W ind Speed Condition
1.0 m/ s
IP Rating
IP 65
Cooling

Cold Start
When the system temperature at startup is −40 to −20 °C (–40 to –4 °F), the system reports to the EM S as a Cold Start
state. RF transmission is not performed and power amp is set to on for warmup.
The temperature is monitored from the start of the device, and the Cold start state is released when the temperature
reaches −20 °C (–4 °F) and reported to the EM S.
Air Pressure
70-106 kPa
Compliant to IEC 60068-2 standards
W ind Pressure
When installed on the back of the antenna or installed on its own (away from the antenna), the RU is functional,
operational, and able to withstand winds in excess of 240 Km/ hour (66.6 m/ s).
