Product Description Introduction This manual contains information and procedures for installation, operation, and maintenance of the PAF0813-E0-001 Multi-Carrier Power Amplifier (MCPA) Indoor System. The manual is organized into chapters as follows. ❑ Chapter 1 - Product Description ❑ Chapter 2 - Controls and Indicators ❑ Chapter 3 - Installation ❑ Chapter 4 - Maintenance ❑ Chapter 5 - Specifications Scope of Manual This 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 Description The PAF-0813-E0-001 system, shown in the Figure 1-1 block diagram, is an 850 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 869 - 894 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 an 850 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.

Site Survey Powerwave 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 Requirements The 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 Inspection This 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 extraneous 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 Recommendations Proper 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.

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 Instructions Install 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. CAUTION: The PAF frame, as factory shipped, weighs approximately 250 lbs (113 kg) to 428 lbs (194 kg) depending on configuration (MCPAs not included). NOTE Reuse shipping pallet washers to secure PAF to installation site floor. 3-2 044-05287 Rev A PAF-0813-E0-001 Installation Instructions Table 3-2 PAF Frame Installation Procedure Step Action 1. Set PAF frame in planned location 2. 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 diameter 3. Move frame back over drilled holes 4. 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 3-2 5. Secure frame in place with red eye lag bolts and appropriate washers Lag Bolt Lock Washer Flat Washer Cabinet Shim Lag Anchor Concrete Figure 3-1 Frame Installation Seismic 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 Connections Connect 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.i WARNING: Turn off external DC power before connecting DC power cables. 044-05287 Rev A 3-3 Installation Instructions PAF-0813-E0-001 Table 3-3 DC Power Installation Procedure Step Action 1. Remove circuit breaker panel top protective cover 2. Connect fourteen individual red power cables, one to each input on the upper row of connections. (designated Row A Figure 3-2) 3. Attach opposite ends of red MCM 250 powr cables to power plant’s main DC bus bar after main shunt. 4. Insert fourteen individual black power cables into front of yellow and green ground connections as shown in Figure 3-3 and tighten screws 5. Attach opposite ends of black power cables to power plant's main DC return bus bar 6. Connect PAF frame to halo grounding system at frame top (four locations) using green 6 AWG cable as shown in Figure 3-4 7. Reinstall circuit breaker panel top protective cover. 8.
