TB9400 Installation and Operation Manual

© Tait Limited March 2015

The security of your base station equipment is a high priority. If the site is 
not fully secure, the base station should at least be locked in a secure 
cabinet to prevent unauthorized access.

The base station modules are grounded by physical contact between the 
module case and the subrack. To ensure a good ground connection you 
must tighten each module retaining clamp securely (refer to 

 for the correct torque).

A threaded grounding connector is provided on the rear of the subrack for 
connection to the site ground point (refer to 

 for more details).

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 
organization or regulatory body.

Always ensure there is adequate ventilation around the base station. 

Notice Do not operate it in a sealed cabinet. You must keep the 
ambient temperature within the specified range, and we strongly rec-
ommended that you ensure that the cooling airflow is not restricted.

Notice The cooling fans are mounted on the front panel and will only 
operate when the panel is fitted correctly to the front of the subrack. To 
ensure adequate airflow through the base station, do not operate it for 
more than a few minutes with the front panel removed (e.g. for servicing 
purposes).

The ambient temperature reading for the base station is provided by the 
temperature sensor located on the front panel circuit board.
