1.6 Recommended Tools
It is beyond the scope of this manual to list every tool that an installation
technician should carry. However, the following tools are specifically
required for installing the TB7100 base station:
■ Phillips #2 tip screwdriver used to connect a DC power supply to the
DC input terminals of the TB7100.
■ Pozidriv PZ3 screwdriver for the M6 screws used to secure the tray to
the cabinet in Tait factory-assembled systems
■ Torx T10 screwdriver for the M3 pan head screws with captured shake-
proof washer and flat washer used to secure the modules in the TB7100.
■ Torx T10 screwdriver for the M3 countersunk screws used to secure the
cover and the heatsink channels to the chassis of the TB7100 tray.
■ Pozidriv PZ1 screwdriver for the M3 pan head self tapping screws used
to secure the fans to the fan mounting frame.
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 TB7100 base station.
1.7 Ventilation
Always ensure there is adequate ventilation around the TB7100 base station.
Do not operate at high duty cycles in a sealed cabinet. You must keep the
ambient temperature within the specified range, and we strongly
recommend you ensure that the cooling airflow is not restricted.
Important The cooling fans are mounted behind the front panel. To
ensure adequate airflow through the base station, do not
operate it for more than a few minutes with the fans discon-
nected (e.g. for servicing purposes).
1.7.1 Cabinet and Rack Ventilation
Refer to Figure 1.2 on page 9.
Adequate cooling airflow is critical to the performance of the TB7100 base
station. The cooling airflow for the TB7100 base station enters through the
front panel and exits at the rear of the tray. For optimum thermal
performance, the heated air that has passed through a base station must not
be allowed to re-enter the air intakes on the front panel.
Each TB7100 Base station requires an unobstructed airflow of 18m
3
/hr. (11
cfm).
