044-05298 Rev A 1-1Chapter 1Product DescriptionIntroductionThis manual contains information and procedures for installation, operation, and maintenance of the PAF-19XX-EX-XXX Multi-Carrier Power Amplifier (MCPA) Indoor System. The manual is organized into chapters as follows.Scope of ManualThis manual is intended for use by service technicians familiar with similar types of equipment. It contains service information required for the equipment described and is current as of the printing date. Changes which occur after the printing date may be incorporated by a complete manual revision or alternatively as additions.Product DescriptionThe PAF-19XX-EX-XXX system, shown in the Figure 1-1 block diagram, is an 1900 MHz, 4-way combined, frame-mounted BTS solution. The PAF system contains three MCPA subracks, each capable of containing up to four MCPAs, three filters, and one DC circuit breaker panel. The MCPA subrack, shown in Figure 1-3, contains linear, feed-forward MCPAs that operate in the 1930 - 1990 MHz range. Each subrack is also equipped with automatic power control (APC), an ethernet connection, an RS-485/RS-232 connection, a filter I/O port, and two cooling fans. The subrack is installed on sliding rails so that it can be pulled forward to allow access to the rear of the subrack.The MCPA, shown in Figure 1-4, is a 1900 MHz module that produces a typical output of 160 watts (52.0 dBm) before system losses, with an instantaneous bandwidth of 25 MHz. The filter assembly, shown in Figure 1-5, if used, supresses unwanted signals and non-linear components of the signal from the amplifiers.The circuit breaker panel, shown in Figure 1-8, consists of two +27 VDC input buses (A and B), and a system circuit breaker panel. The panel receives +27 VDC from the BTS and then distributes circuit breaker protected DC power to the individual subracks.Functional And Physical SpecificationsPAF-19XX-EX-XXX system functional and physical specifications are listed in Chapter 5.❑Chapter 1 - Product Description❑Chapter 2 - Controls and Indicators❑Chapter 3 - Installation❑Chapter 4 - Maintenance❑Chapter 5 - Specifications

044-05298 Rev A 3-1Chapter 3InstallationIntroductionThis chapter contains unpacking, inspection, installation instructions, and recommendations for installing the PAF-19XX-EX-XXX MCPA Indoor System.Site SurveyPowerwave recommends that a site survey be performed prior to equipment ordering or installation. Performing a detailed site survey reduces or eliminates installation and turn-up delays. Pay particular attention to AC or DC power availability, cooling needs, floor space, and RF/DC cabling/breaker requirements. See Chapter 5 for system dimensions and weights.Space RequirementsThe PAF system requires the following floor space for clearance (W x D x H): 28.5 inches (724 mm) x 78.2 inches (1986 mm) x 38.5 inches (978 mm). To properly service the system, an additional 48 inches (1220 mm) is required in the front of the unit. To permit proper airflow, allow a minimum of 8.27 inches (210 mm) behind the PAF.Unpacking and InspectionThis equipment has been operated, tested and calibrated at the factory. Carefully open the containers and remove the equipment. Retain all packing material that can be reassembled in the event that the unit must be returned to the factory. Please perform the following steps:❑Visually inspect equipment for damage that may have occurred during shipment. If possible, in the presence of the delivery person. ❑Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extrane-ous packing material in connectors.If the equipment is damaged, file a claim with the carrier once the extent of any damage is assessed. If the equipment must be returned to the factory, contact the factory for a Return Material Authorization (RMA) as described in Chapter 4.Electrical Service RecommendationsProper AC line conditioning and surge suppression is necessary on the primary AC input to the +27 VDC power source. Powerwave recommends that all electrical service be installed in accordance with the National Electrical Code (NEC) and any applicable state or local codes.Table 3-1 lists a sample of DC cable ratings.

Cooling Requirements PAF-19XX-EX-XXX3-2 044-05298 Rev ACooling RequirementsEach MCPA at full power generates the BTUs per hour listed in Table 3-3. A 1-ton air conditioner offsets 12,000 BTUs of heat. The MCPA operates within the temperature environment specified in Chapter 5.Fan speed is dependent on MCPA operating temperature. The fans remain off until the MCPAs exceed +43°C base plate temperature. Once enabled, the fan remains on until all MCPA base plate temperatures are below +41°C. Installation InstructionsInstall the PAF frame, DC and RF connections, alarms, and MCPAs as described in the following paragraphs.PAF To install the PAF frame, perform the instructions in Table 3-4.Table 3-1 Sample of DC Cable RatingsAWGorMCM mm2Copper3 Conductor In Raceway Single Conductor In Free Air75°C 90°C 110°C 75°C90°C110°C10 540 45 50 55 658 8 57 55 60 70 75 85613 76 70 80 95 100 1204 21 101 95 105 125 135 160234 135 125 135 170 185 2101 42 158 145 160 195 215 245053 183 165 190 230 250 28500 67 212 195 265 300000 85 245 225 310 3500000 107 287 260 360 405MCM250 127 320 290 405 455MCM300 152 359 320 445 505Based on ambient temperature of 30×C (86×F)100% Load Factor Source: Industrial Electric Wire & Cable Inc., Technical Guide Vol. 4M 11/99, Table III Suggested Ampacities - All Types of Insulations; Based on National Electric CodeCAUTION: The PAF frame, as factory shipped, weighs approximately 250 lbs (113 kg) to 428 lbs (194 kg) depending on configuration (MCPAs not included). During unpacking and installation, be careful with the semi-rigid cables. Protect the cables from damage by avoiding contact with doorways or other equipment. Do not use the cables as handles for moving the components or the frame.NOTE Reuse shipping pallet washers to secure PAF to installation site floor.

PAF-19XX-EX-XXX Installation Instructions044-05298 Rev A 3-3Figure 3-1 Frame InstallationSeismic Brace (Optional)The PAF system meets GR-63-CORE, Section 4.4.1, Zone 4 compliance. If additional bracing is required, Powerwave offers an optional seismic brace kit for those circumstances. Please contact a Powerwave sales representative for additional information and assistance.DC ConnectionsConnect and verify DC power cables between the BTS power plant and the PAF system circuit breaker panel and PAF return bus located at the top of the PAF as instructed in Table 3-5. Required power is +27 VBC, and each power input is directly connected through the circuit breaker in the front of the panel to the power output directly below it in the panel.Table 3-2 PAF Frame Installation ProcedureStep Action1. Set PAF frame in planned location2. Mark floor drill holes on floor where lag bolts will be installed. Move frame to side. Refer to lag bolt manufacturer’s instructions for hole depth and diameter3. Move frame back over drilled holes4. Use a level to ensure frame is not leaning. Insert shims between frame base and floor to level frame. Shims should wrap around lag bolts as shown in Figure 3-25. Secure frame in place with red eye lag bolts and appropriate washersWARNING: Turn off external DC power before connecting DC power cables.ConcreteLag AnchorShimCabinetFlat WasherLock WasherLag Bolt
