TB8100 Installation and Operation Manual Installation 63

You can also obtain the TBA0ST2 tool kit from your nearest Tait Dealer or

Customer Service Organisation. It contains the basic tools needed to install,

tune and service the TB8100 BSS.

5.7 Ventilation

Always ensure there is adequate ventilation around the TB8100 BSS. Do

not operate it in a sealed cabinet. You must keep the ambient temperature

within the specified range, and we strongly recommended that you ensure

that the cooling airflow is not restricted.

Important 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

BSS, do not operate it for more than a few minutes with the

front panel removed (e.g. for servicing purposes).

Ambient Air Temperature Sensor

The ambient air temperature reading

for the TB8100 BSS is provided by

the ambient air temperature sensor

PCB

b fitted to the PA control PCB.

The sensor PCB is inserted through

slots in the control PCB and heatsink

to be positioned between the heatsink

fins.

Important If the sensor PCB is to provide accurate ambient tempera-

ture readings, it must have forced airflow and must not

come into contact with the metal of the heatsink fins. Do

not stack PAs with the fins together. It is possible for

the fins on one heatsink to slide between the fins on the

other heatsink. This can damage the sensor PCB, and pos-

sibly result in the heatsink fins becoming locked together.
