All rights reserved.Powerwave Technologies and the Powerwave logo are registered trademarks.Powerwave Technologies Inc. reserves the right to make changes to documentation and equipment, including but not limited to component substitution and circuitry changes. Changes that impact this document may be subsequently incorporated in a later revision of this document.This Powerwave product is designed to operate within the Normal Operating (typical operating) ranges or conditions specified in this document. Operation of this equipment beyond the specified ranges in this document may cause (1) spurious emissions that violate regulatory requirements; (2) the equipment to be automatically removed from service when maximum thresholds are exceeded; or (3) the equipment to not perform in accordance with its specifications. It is the Operator's responsibility to ensure this equipment is properly installed and operated within Powerwave operating specifications to obtain proper performance from the equipment and to comply with regulatory requirements.The rated output power of a Nexus RT is for multiple carriers. As long as the composite power does not exceed the rated power (28 dBm for North America), derating is not required for multiple carriers. For situations where regulatory requirements require reduced interference to adjacent band users, the rating would have to be reduced by 3 dB. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. Input power is rated at 115/230VAC, 50/60Hz, and should be protected based on the power and fuse specifications in Chapter 5 of this manual. Power strips should, at a minimum, conform to this requirement to prevent equipment dam-age and possible overload.Federal Communications Commission (FCC)This device complies with the technical standards governing mobile radio devices in accordance with FCC Rules. This device is intended to facilitate the transmission of mobile radio devices in the cellular and PCS services, and its opera-tion by end users or others requires carrier consent under FCC rules. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to CRF47 part 15 of the FCC rules. This equipment is also certified to CRF47 part 22 (cellular) and part 24 (PCS) of the FCC Rules depending on the band of operation. Changes or modifications not expressly approved by PowerwaveTechnologies, Inc. for compliance could void the user’s author-ity to operate this equipment. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interfer-ence to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.Industry Canadian RequirementsAll Powerwave apparatus introduced in the Canadian market meet all requirements of the Canadian Interference-Caus-ing Equipment Regulations. The -20dB bandwidth at Downlink at 1900 MHz band is 61 MHz. The -20dB bandwidth at Uplink at 1900 MHz band is 61.2 MHz. The -20dB bandwidth at Downlink at 850 MHz is 27 MHz. The -20dB bandwidth at uplink at 850 MHz is 27 MHz. The output impedance of the unit referenced in this document is 50 Ohms. The Manu-facturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier sig-nals are present, the rating would have to be reduced. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. The input signal is optical so input impedance require-ments are not applicable.Powerwave Technologies Inc., 1801 East St. Andrew Place, CA 92705 Santa Ana, USA.

044-05311 Rev A iiiPrefaceWarning, Cautions, and NotesWarnings, Cautions, and Notes are found throughout this manual where applicable. The associated icons in warnings and cautions are used to quickly identify a potential condition that could result in the consequences described below if precautions are not taken. Notes clarify and provide additional information to assist the user.WARNING: The warning symbol means danger. You are in a situation that could cause bodily injury or death. Before you work on any equipment, be aware of the hazards involved with elec-trical and RF circuitry and be familiar with standard practices for preventing accidents. CAUTION: The caution symbol means the potential exists for equipment damage or loss of data. NOTE: Notes contain helpful suggestions or references to material not covered in the document.SafetyAny personnel involved in installation, operation, or service of units included in a Powerwave repeater systemmust understand and follow the points below:Powerwave repeaters are designed to receive and amplify signals from one or more base stations and retransmit the signals to one or more mobile stations. And, also to act the other way round, that is to receive signals from one or more mobile stations, amplify and retransmit the signals to the base sta-tions. Powerwave repeater systems must be used exclusively for this purpose and nothing else.Units supplied from the mains must be connected to grounded outlets and in conformity with the local prescriptions. For outdoor use, the power cord should meet at least IP65 encapsulation requirements. Do not turn the main power on until you are ready to commission the equipment.Power supply units supplied from the mains contain dangerous voltage that can cause electric shock. Disconnect the mains prior to any work in such a unit. Local regulations are to be followed when servic-ing such units. Only authorized service personnel are allowed to service units while the mains are con-nected.When working on an a repeater on high ground, for instance on a mast or pole, be careful not to drop parts or the entire repeater. Falling parts can cause serious personal injury.All RF transmitting units, including the Nexus RT Repeater, will generate radio signals and thereby give rise to electromagnetic fields that may be hazardous to the health of any person who is exten-sively exposed close to an antenna. Beryllium oxide (BeO) may be contained in power devices, for instance in dummy loads in directional couplers (DCC), in combiner units (CMB), and in attenuators on the FON board. Beryllium oxide is poi-sonous if present as dust or smoke that can be inhaled. Do not file, grind, machine, or treat these parts with acid.Coaxial cables used in many Powerwave systems have the insulation made of PTFE, polytetrafluoro ethylene, that gives off small amounts of hydrogen fluoride when heated. Hydrogen fluoride is poison-ous. Do not use heating tools when stripping off coaxial cable insulation. No particular measures are to be taken in case of fire because the emitted concentration of hydrogen fluoride is very low.
Electrostatic Discharge (ESD) Nexus RTiv 044-05311 Rev AWarning SignsThe following warning signs must be observed and be kept clean and readable.Beryllium oxideThis warning sign to the left is applied to boards and units which contain beryllium oxide parts.This warning sign below is applied at the bottom, inside the cabinet, below the power supply unit.Human Exposure to RF RadiationSafe distances must be kept when working around antennas. The following paragraphs describe the cautions to be aware of during the installation and maintenance of antenna systems and how to calculate safety distances needed for RF radiation at different antenna power and frequencies.Repeater AntennasTo be able to receive and transmit signals, a repeater is connected to a donor antenna directed towards the base station and a service antenna directed towards the coverage area. A fiber optic cable from the base station might, however, be substituted for the donor antenna.Installation and Maintenance of Antenna SystemsInstallation and maintenance of all antenna systems must be performed with respect to the radiation exposure limits for public areas. The antenna radiation level is affected by the output power, antenna gain, and transmission devices such as cables, connectors, splitters and feeders. Also have in mind the system minimum coupling loss, typically between 25dB and 35dB, is determined by a standard with the purpose to protect base stations from noise and other performance dropping effects.Radiation ExposureThe World Health Organization (WHO) and International Commission on Non-Ionising Radiation Protection (ICNIRP) have determined recommendations for radiation exposure. ICNIRP recommends not to exceed the following radiation power for public exposure:Frequency Radiation power800/900 MHz 4.5W/m²1800/1900 MHz 9.0W/m²2100 MHz 10.0W/m²For antennas larger than 20cm the maximum radiation power can be calculated by using the following formula:Electrostatic Discharge (ESD) ESD can severly damage essential parts of the equipment if not handled carefully. Parts on Printed Circuit Board Assemblies (PCBA) as well as other parts in the equipment are sensitive to ESD. Never touch the PCBA or uninsulated conductor surfaces unless absolutely necessary.If you must handle the PCBAs or uninsulated conductor surfaces, use ESD protective equipment or first touch the chassis with your hand. Never let your clothes touch PCBAs or uninsulated conductor surfaces and always store PCBAs in ESD-safe bags.S= P/(4πr2)S = Radiation power in W/m²P = Output power in Wr = Distance between antenna and human in metersBerylliumoxidehazardBERYLLIUM OXIDE(Toxic)used in equipmentsee instruction book
