4.4 Environmental Conditions
4.4.1 Operating Temperature Range
The operating temperature range is –30°C to +60°C (–22°F to +140°F)
ambient temperature for the 25W base station and –30°C to +50°C (–22°F
to +122°F) ambient temperature for the 50W and 40W base stations.
Ambient temperature is defined as the temperature of the air at the intake to
the cooling fans.
4.4.2 Humidity
The humidity should not exceed 95% relative humidity through the
specified operating temperature range.
4.4.3 Dust and Dirt
For uncontrolled environments, the level of airborne particulates must not
exceed 100µg/m

4.5 Grounding and Lightning Protection
4.5.1 Electrical Ground
The base station modules are grounded by physical contact between the
module mounting points and the chassis. To ensure a good ground
connection you must tighten each module securely (for the correct torque
refer to “Replacing Modules” in the installation and operation manual).
A threaded grounding connector is provided on the rear of the tray for
connection to the site ground point (for more details refer to “Connections”
on page 65).
4.5.2 Lightning Ground
It is extremely important for the security of the site and its equipment that
you take adequate precautions against lightning strike. Because it is outside
the scope of this manual to provide comprehensive information on this
subject, we recommend that you conform to your country's standards
organisation or regulatory body.
