Installation
This chapter describes how to install the TB8100 BSS in a standard 19 inch
rack or cabinet. It also provides some general information on safety
precautions and site requirements. We recommend that you read the entire
chapter before beginning the installation.
5.1
Personal Safety
Lethal Voltages
Warning!!
The PMU contains voltages that may be lethal.
Refer to the ratings label on the rear of the
module.
The TB8100 BSS must be installed so that the rear of the PMU is located
in a service access area.
Disconnect the mains IEC connector and wait for five minutes for
the internal voltages to self-discharge before dismantling. The AC
power on/off switch does not isolate the PMU from the mains. It
breaks only the phase circuit, not the neutral.
The PMU should be serviced only by qualified technicians. All servicing
should be carried out only when the PMU is powered through a mains
isolating transformer of sufficient rating. We strongly recommend that
the mains power to the whole of the repair and test area is supplied via an
earth leakage circuit breaker.
Explosive Environments
Warning!!
Do not operate TB8100 BSS equipment near
electrical blasting caps or in an explosive atmosphere. Operating the equipment in these environments is a definite safety hazard.
Proximity to RF Transmissions
Do not operate the transmitter when someone is standing within 90cm (3ft)
of the antenna. Do not operate the transmitter unless you have checked that
all RF connectors are secure.

5.5
Grounding and Lightning Protection
Electrical Ground
The TB8100 BSS 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 “Final
Reassembly” on page 81 for the correct torque setting).
A threaded grounding connector is provided on the rear of the subrack for
connection to the site ground point (refer to “Connection” on page 83 for
more details).
Lightning Ground
It is extremely important for the security of the site and its equipment that
you take adequate precautions against lightning strike. While it is outside
the scope of this manual to provide comprehensive information on this
subject, the following guidelines apply:
5.6
■
install a suitable lightning rod at the top of the tower and connect it to a
secure ground point with appropriate conductors and connectors
■
position site buildings and equipment within the cone of protection
provided by the grounded tower
■
protect all cables entering the site to prevent lightning energy from
entering site buildings.
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 TB8100 BSS:
62
Installation
■
Pozidriv PZ3 screwdriver for the M6 screws used to secure the subrack
to the rack or cabinet, and also for the DC input terminals on the PMU
■
Pozidriv PZ2 screwdriver for the M4 screws used to secure the module
retaining clamps
■
0.25in or 6mm flat blade screwdriver for the fasteners used to secure the
front panel to the subrack
■
8mm AF spanner for the SMA connectors.
TB8100 Installation and Operation Manual

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
TB8100 Installation and Operation Manual
© Tait Electronics Ltd March 2004
If the sensor PCB is to provide accurate ambient temperature 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 possibly result in the heatsink fins becoming locked together.
Installation
63
Cabinet and Rack Ventilation
Refer to Figure 5.2 on page 65.
The cooling airflow for the TB8100 BSS enters through the front panel and
exits at the rear of the subrack. For optimum thermal performance, the
heated air that has passed through a BSS must not be allowed to re-enter the
air intakes on the front panel. Any space at the front of the cabinet not
occupied by equipment should be covered by a blanking panel.
To allow enough cooling airflow through a cabinet-mounted BSS, we
recommend the following:
■
■
■
an area of at least 150cm2 (23in2) of unrestricted ventilation slots or holes
in front of the air intakes for the fans for each subrack; for example,
thirty 6x85mm (0.25x3.3in) slots will allow the recommended airflow
a vent in the top of the cabinet with an area of approximately 150cm2
(23in2) per subrack, or a similar area of ventilation per subrack at the rear
of the cabinet behind each subrack
a 2U gap at the top of the cabinet.
Note
The ventilation opening must be unrestricted. If the slots or holes
are covered with a filter, mesh or grille, the open area must be
increased to allow the same airflow as an unrestricted opening.
The maximum ambient temperature entering the cabinet must not exceed
+60°C (+140°F).
If the TB8100 BSS is installed in a rack or cabinet with other equipment
with different ventilation requirements, we recommend that the TB8100 be
positioned below this equipment.
Auxiliary Extractor
Fans
The TB8100 BSS does not require auxiliary extractor fans mounted in the
top of the cabinet. If your cabinet is already fitted with fans, the following
procedures apply:
■
if there are six or more 120mm (4.75in) fans, each capable of extracting
160m3 per hour (94.2CFM), they must run continuously
■
if there are fewer than six fans, you must remove them and ensure the
vent in the top of the cabinet has an area of approximately 150cm2
(23in2) per subrack.
If you have any other configuration, the performance of your system will
depend on how closely you comply with the TB8100 BSS airflow
requirements described above.

Optional Slide Mounting Rails
You can also use TBA2141 slide mounting rails b when mounting the
TB8100 BSS in a cabinet, as shown in Figure 5.6 below. These rails will
support the BSS while you slide it into the cabinet.
However, you must still secure the BSS to the cabinet with four M6 screws
through the main mounting holes on the front of the subrack, as shown in
Figure 5.4 on page 67.
Figure 5.6
Optional Slide Mounting Rail - Rear View
Important
The slide mounting rails are not suitable for transporting a
cabinet fitted with a fully built-up TB8100 BSS. In this
case, you must also fit the TBA2140 auxiliary support
brackets to the upper set of rear mounting holes c.
Cabling
General
We recommend that you try to route all cables to and from the TB8100 BSS
along the side of the cabinet so the cooling airflow is not restricted.
DC Power Cabling
DC power cables should be well supported so that the terminals on the
PMU and on the ends of the cables do not have to support the full weight
of the cables.

Power Supply Connections
AC Power
The TB8100 PMU is designed to accept a mains input of 88 to 264VAC at
45 to 65Hz. We recommend that a standard 3-wire grounded outlet is used
to supply the AC power. The socket-outlet must be installed near the
equipment and must be easily accessible. This outlet should be connected
to an AC power supply capable of providing a maximum of 600W. The
requirements of two typical AC supplies are given in the following table.
Nominal Supply
Current Requirement

The TB8100 PMU is designed to accept a DC input of 10.3 to 15.5VDC
with negative or positive ground. There is a minimum DC start-up
threshold to prevent damaging a battery which has little capacity left.
You must connect the DC supply from the battery to the PMU via a fuse or
DC-rated circuit breaker with a rating of 60A. The DC input leads should
be of a suitable gauge to ensure less than 0.2V drop at maximum load over
the required length of lead.

System Connections
The reciter can be fitted with an optional system interface PCB which
provides the links between the reciter’s internal circuitry and external
equipment. This PCB is securely mounted to the reciter’s chassis and is
connected to the control PCB with a flexible connector. The system
interface PCB is fitted with industry-standard connectors and several
standard types are available for different applications.
The circuitry on the system interface PCB provides additional signal
processing so that the outputs meet standard system requirements. It also
enables the PCB to identify itself to the reciter control circuitry.
The system interface PCB is removable, which makes it possible to change
the application of a reciter by removing one type of PCB and fitting another.
Only one system interface PCB can be fitted to a reciter at any one time.
This section provides details on the system interface PCBs available at the
time of publication. Other types may be developed for future applications.
