TB8100 Installation and Operation Manual Installation 31© Tait Electronics Ltd June 20034 InstallationThis 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.4.1 Personal SafetyLethal VoltagesWarning!! 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 EnvironmentsWarning!! Do not operate TB8100 BSS equipment near electrical blasting caps or in an explosive atmos-phere. Operating the equipment in these envi-ronments is a definite safety hazard.Proximity to RF TransmissionsDo 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.
32 Installation TB8100 Installation and Operation Manual© Tait Electronics Ltd June 2003High TemperaturesTake care when handling a PMU or PA which has been operating recently. Under extreme operating conditions (+60°C [+140°F] ambient air temperature) the external surfaces of the PMU and PA can reach temperatures of up to +80°C (+176°F).4.2 Equipment SafetyESD PrecautionsImportant This equipment contains devices which are susceptible to damage from static charges. You must handle these devices carefully and according to the procedures described in the manufacturers’ data books.We recommend you purchase an antistatic bench kit from a reputable manufacturer and install and test it according to the manufacturer’s instructions. Figure 4.1 shows a typical antistatic bench set-up.You can obtain further information on antistatic precautions and the dangers of electrostatic discharge (ESD) from standards such as ESD S4.1-1997 (revised) or BS EN 100015-4 1994. Aerial LoadThe TB8100 BSS equipment has been designed to operate safely under a wide range of aerial loading conditions. However, we strongly recommend that the transmitter should always be operated with a suitable load to prevent damage to the transmitter output power stage.Figure 4.1 Typical Antistatic Bench Set-upto building ground or mains ground via 1M ohm series resistorconductive wrist strap dissipative rubber bench mat

34 Installation TB8100 Installation and Operation Manual© Tait Electronics Ltd June 2003Dust and DirtFor uncontrolled environments, the level of airborne particulates must not exceed 100µg/m3.4.5 Grounding and Lightning ProtectionElectrical GroundThe 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 53 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 55 for more details).Lightning GroundIt 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:■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.4.6 Recommended ToolsIt 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:■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 Installation 35© Tait Electronics Ltd June 2003You 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.4.7 VentilationAlways 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 SensorThe 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.b
36 Installation TB8100 Installation and Operation Manual© Tait Electronics Ltd June 2003Cabinet and Rack VentilationRefer to Figure 4.2 on page 37.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.

38 Installation TB8100 Installation and Operation Manual© Tait Electronics Ltd June 20034.8 Installing the Base Station SystemCaution A TB8100 subrack complete with modules can weigh up to 28kg (62 lb), or up to 30kg (66 lb) com-plete with packaging. We recommend that you remove the modules from the subrack before mov-ing the equipment, or have another person help you with the lifting. In all cases follow safe lifting prac-tices.Unpacking the EquipmentUnpacking the TB8100 BSS The TB8100 BSS is packed in a strong corrugated cardboard carton with top and bottom foam cushions. To prevent personal injury and damage to the equipment, we recommend that two people unpack the BSS.1. Rotate the carton carefully onto its side b and then onto its top c.2. Cut the tape securing the flaps at the bottom of the carton and fold them flat against the sides d.Figure 4.3 Unpacking the TB8100 BSSdghiefbc
TB8100 Installation and Operation Manual Installation 39© Tait Electronics Ltd June 20033. Rotate the carton carefully onto its side e, and then onto its bottom f, ensuring that none of the flaps is trapped underneath.4. Slide the carton upwards over the foam cushions and lift it away g.5. Remove the cushion from the top of the BSS h and then lift the BSS out of the other cushion i. Disposal of Packaging If you do not need to keep the packaging, we recommend that you recycle it according to your local recycling methods. The foam cushions are CFC- and HCFC-free and may be burnt in a suitable waste-to-energy combustion facility, or compacted in landfill.Mounting the SubrackCaution We recommend that you remove the modules from the subrack before lifting it (refer to “Replacing Modules” on page 43), or have another person help you with the lifting.Figure 4.4 Subrack Mounting Pointsbmain mounting holes - front cauxiliary mounting holes - rearfront viewrear viewbc
40 Installation TB8100 Installation and Operation Manual© Tait Electronics Ltd June 20031. Remove the front panel, as described in “Preliminary Disassembly” on page 43.2. Fit the subrack into the cabinet or rack and secure it firmly with an M6 screw, flat and spring washer in each of the four main mounting holes b, as shown in Figure 4.4 on page 39.Note If you need extra mounting security, there are additional mount-ing holes c provided at the rear of the subrack for auxiliary sup-port brackets.Auxiliary Support BracketTBA2140 auxiliary support brackets can be fitted to the rear of the TB8100 subrack to provide additional mounting security. Figure 4.5 below shows a standard TBA2140 bracket b fitted in a typical Tait Electronics cabinet c. If you are not using a Tait cabinet, you may have to make your own brackets to suit your installation.Important Yo u must fit the auxiliary support brackets if you intend to transport a cabinet fitted with a fully built-up TB8100 BSS.We also recommend that you fit the brackets under the following conditions:■when the installation is in an area prone to earthquakes■when third party equipment is installed hard up underneath the TB8100 BSS subrack.Figure 4.5 Auxiliary Support Bracketcb
TB8100 Installation and Operation Manual Installation 41© Tait Electronics Ltd June 2003Optional Slide Mounting RailsYou can also use TBA2141 slide mounting rails b when mounting the TB8100 BSS in a cabinet, as shown in Figure 4.6 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 4.4 on page 39.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.CablingGeneral 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.Figure 4.7 below shows two recommended methods of securing these cables to prevent straining either set of terminals.Figure 4.6 Optional Slide Mounting Rail - Rear Viewbc
