Chapter 1 CCU/Repeater Basics 2 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential CCU/Repeater Components The CCU 100 and Repeater 100 come in two basic configurations; they may have either internal GPS/WAN antennas or external GPS/WAN antennas. The external CCU/Repeater configuration replaces the internal GPS/WAN antennas with external antenna connectors that allow both GPS and WAN antennas to be mounted externally. In the case of the Repeater 100, only an external GPS connection is provided; a WAN modem is not present in a repeater. Both internal antenna and external antenna configurations allow for remotely mounting the 900 MHz antenna by removing the antenna from the unit and attaching it to a remote antenna mounting plate. Since the CCU/Repeater may be installed in an outdoor environment, each component of the CCU/Repeater is weather-tight and can withstand wind requirements in excess of 100 MPH. Note When determining the configuration of the CCU/Repeater, be sure to review the Fixed Network 100 Ordering Guide for specific part numbers, cable lengths, and various options for the components. CCU/Repeater Module The CCU/Repeater case houses the backup battery, GPS receiver, optional WAN radio, processing board and 900 MHz radio. The antennas for the radios can be either internally or externally connected, depending on the CCU/Repeater configuration. Caution Only authorized Itron personnel may open this device. Unauthorized access or modifications to this device voids the warranty. Per FCC rules, unapproved modifications or operation beyond or in conflict with these instructions for use could void the user's authority to operate the equipment.

There are three antennas that may be used for the 900 MHz radio link. • A standard vertically polarized antenna that is directly attached to the CCU/Repeater. • A standard vertically polarized antenna (5 dBi) that can be connected remotely. • A high-gain vertically polarized remote antenna (8.15 dBi) that is mounted remotely in place of the direct attached solution. Remote antennas must be properly grounded during installation. When a remote antenna is used, a lightning arrestor is supplied for this purpose.
Chapter 1 CCU/Repeater Basics 6 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential Coaxial cable used to connect the 900 MHz antenna to the CCU/Receiver must be properly grounded. See Lightning Arrestor on page 12 for more information. All coaxial cable connections must be properly weather-proofed per industry standards, unless otherwise specified. If the CCU/Repeater is installed indoors, only the connections located outside need to be weather-proofed. When the CCU/Repeater is ordered with a remote 900 MHz antenna kit, some associated mounting hardware is included. Coaxial cables for the remote 900 MHz antennas are not included in the kit. These cables must be provided by the installer. Please see Coaxial Cable on page 13 for coaxial cable specifications. For more information, see: • Antenna Specifications on page 58 • Remote 900 MHz Antenna Placement on page 10 • Grounding the Remote/External Antenna Systems on page 11
CCU 100 and Repeater 100 Installation Guide 7 Proprietary and Confidential This chapter describes how to prepare for a CCU/repeater installation. Installation Profiles The CCU/Repeater can be installed in a variety of configurations and locations. Depending on the installation location, the CCU or Repeater components may be installed all in the same place (as an integrated solution), or the GPS/WAN antennas may be installed externally from the CCU/Repeater and the 900 MHz antenna can be installed remotely (as a distributed solution). For example, the CCU/Repeater can be installed at the base of a water tower, the external GPS/WAN antenna system can be mounted further away for optimum reception, and the 900 MHz antenna can be placed at the top of the water tower. The following profiles have been identified for CCU installation. Location Description Utility pole The CCU/Repeater is installed on a utility pole. The CCU/Repeater should be mounted as high as possible on the pole for optimum reception. Light pole The CCU/Repeater is installed on either a light pole or the davit arm that extends from the light pole. The CCU/Repeater should be mounted as high as possible on the pole for optimum reception. Outdoor wall or pipe with remote 900 MHz antenna The CCU/Repeater is installed on an outside wall or pipe with the 900 MHz antenna remotely mounted to achieve the maximum elevation and reception. Indoor wall or pipe with remote 900 MHz antenna and external GPS/WAN antennas The CCU/Repeater is installed inside an equipment room with the 900 MHz antenna remotely mounted to achieve maximum elevation and reception. The WAN (or other digital cellular) and GPS antenna are externally mounted to provide acceptable coverage. Pipe The CCU/Repeater is secured to a pipe or fence railing (from 2 to 3.5 inches in diameter). This type of installation typically occurs on the tops of water towers. For more information on these various profiles, as well as the Itron-recommended profile, see Chapter 3, Installing the CCU/Repeater on page 17. CHAPTER 2 Planning a CCU/Repeater Installation
Chapter 2 Planning a CCU/Repeater Installation 8 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential Siting CCUs/Repeaters CCUs/Repeaters are installed in the field on a variety of surfaces, such as wooden or metal walls, metal pipes, fence railing, and utility poles. When determining where to place the CCU/Repeater, there are four primary considerations: • Siting for optimum RF reception. • Siting for optimum GPS and/or WAN reception. • Availability of Ethernet connection (if required). • Availability of power connection. • Availability of a structure or location that can physically support the CCU/Repeater and its mounting hardware. Caution Always ensure that you have permission to install a CCU/Repeater at your chosen site prior to beginning installation. Propagation Study and CCU/Repeater Site Selection Prior to installing a CCU/Repeater in the field, consult with Itron to perform a propagation study. This study: • Evaluates the quantity and types of endpoints in the network. • Assesses environmental and geographical considerations related to CCU/Repeater installation. • Optimizes CCU/Repeater placement in the network for the best possible reception. • Helps influence the physical and structural implications of mounting a CCU/Repeater to a given surface. Once the propagation study is complete, you can determine exactly where to install CCUs/Repeaters and what they will be mounted to. GPS and WAN Coverage CCUs/Repeaters must be installed in locations where a GPS signal is strong and consistent. If WAN is being used as the communications backhaul for the network, a strong and consistent WAN signal is required as well (for CCUs only). If the signal is too weak, or its availability fluctuates, the CCU/Repeater can not gather accurate date/time information or communicate with the Fixed Network software. Itron recommends using a handheld GPS unit to verify that your CCU/Repeater or external GPS antenna mounting location can receive a signal from at least three satellites.
Siting CCUs/Repeaters CCU 100 and Repeater 100 Installation Guide 9 Proprietary and Confidential To ensure the best possible signal, avoid installing the CCU/Repeater or the external antennas in the following ways: • Adjacent to or between tall buildings, signs, towers, or bridges. • Near swaying limbs, branches, or cables that could strike and damage the antenna. • Between, beneath, or near highway overpasses, elevated train platforms, or tunnels. • Near objects or devices attached to the same pole. • Within 500 feet of high power radio frequency (RF) transmitters (such as paging transmitters, cellular transmitters, and municipal communications transmitters). • Near potential broadband sources of radiated RF energy (such as power line transformers, RADAR transmitters, cellular antennas, and neon or fluorescent signs). • Inside metal enclosures (the antennas will not communicate if surrounded by metal) or inside a building. The CCU/Repeater can be installed in a building or other metal enclosure, but the antennas must be installed externally. Warning Before installing a CCU/Repeater near or on the same pole as a transformer, consult the National Electrical Safety Code (NESC), local utilities, municipalities, and cable and telephone companies for recommended distances from transformers and power lines. AC Service Requirements A 90 to 265 VAC 10A power source is required at the installation site for the CCU/Repeater, unless you are using the DC CCU/Repeater or the solar CCU/Repeater. For more information on these options, see Mains Power Installation Profiles on page 13 or Solar Power Installation Profiles on page 44. External Ethernet Connections If the Ethernet is used as the communications backhaul, the CCU installation site must have Ethernet access. Also, be sure to use weatherproof cables in this type of installation. Caution When using Ethernet as the communications backhaul, the CCU must be identified as Ethernet-based when performing Initial Collector Setup (ICS). Failure to do so prohibits the CCU from communicating with the Network Collection Engine.
Chapter 2 Planning a CCU/Repeater Installation 10 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential Remote 900 MHz Antenna Placement Antenna placement is one of the most important factors in determining your overall system performance. Careful consideration must be given to proper antenna placement. Follow the general guidelines below when determining the ideal location for a remote-mounted 900 MHz antenna. • The antenna must be mounted vertically. • The antenna needs to be mounted in a location where it has a clear unobstructed 360 degree view of the horizon. The antenna receives and transmits in all directions. Any objects such as building walls, nearby metal surfaces or other obstructions will interfere with the proper operation of the antenna. Mounting on a rooftop, where nearby buildings are higher than the installation location, is not an ideal location for the antenna. • Do not mount the antenna near existing RF radiating antennas. If existing RF radiators are nearby, the horizontal separation distance to the radiator must be a minimum of 100 feet and/or 10 feet of vertical separation. In instances where nearby RF radiators are present, conduct an intermodulation interference study to evaluate the potential for interference and any effects it may have on system performance. Consult with your Itron systems engineer for more information. • Height is preferred for optimal performance. Mount the antenna as high as possible, but Itron recommends that you install the antenna no higher than 100 feet. If the antenna is going to be more than 100 feet above the CCU, Itron recommends using a Tower CCU 100. A side arm antenna installation must be done if the 900 MHz antenna is mounted where it does not have an unobstructed 360-degree view. Refer to the following guidelines for a side arm antenna installation. • For the 900 MHz antenna, the minimum standoff distance is 24 inches, where the interfering structural members are four inches or less in diameter and spaced more than eight feet apart. • For structural members between 4 and 10 inches in diameter, a sliding scale of 2 to 5 feet is to be used. (For example, a 24 inch standoff at 4 inch diameter to a 60 inch standoff at 10 inch member diameter.) Provide Itron with any conditions that may impact the CCU/Repeater's performance.
Siting CCUs/Repeaters CCU 100 and Repeater 100 Installation Guide 11 Proprietary and Confidential Grounding the Antenna System To minimize the potential for a lightning event, it is essential that remote/external antenna systems be properly grounded. Proper grounding prevents the accumulation of static charges on the antenna system and also provides a direct discharge to ground for any acquired charges. All grounding materials and procedures must meet or exceed local codes. Use coaxial grounding kits recommended by the coaxial cable manufacturer. Warning Under no circumstances should the antenna grounding wires be run inside a building. Always install ground bars and grounding material on the exterior of buildings. The recommended procedure for grounding an antenna system is as follows: • Mount a copper ground bar near the antenna. This is the top ground bar. • Mount a second copper ground bar near the CCU/Repeater. This is the bottom ground bar. • Connect the two ground bars with a #6 gauge green jacketed stranded wire or a #2 solid copper wire. • Ground the antenna mount and the top coaxial ground kit to the top ground bar. • Ground the bottom coaxial ground kit and the lightning arrestor to the bottom ground bar. • Connect the bottom ground bar to one or more earth ground rods. • All ground wires should be connected straight to ground, with no right angle turns or sharp bends in the wires. • Install ground leads on coaxial grounding kits without loops or bends and install grounding kits in the proper orientation per the manufacturer's specifications.
Chapter 2 Planning a CCU/Repeater Installation 12 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential Lightning Arrestor A lightning arrestor (or surge protector) capable of withstanding multiple lightning strikes should be installed when using a remote/external antenna. This helps protect the CCU/Repeater in the event of a lightning strike. The lightning arrestor is fitted to the coaxial antenna cable at the SURGE end and the RF jumper cable that connects to the CCU/Repeater module at the PROTECTED end. It includes a bulkhead connector interface that mounts to a ground plate with a washer and nut. The arrestor is also furnished with a ground lug, if your installation does not have provisions for a ground plate. The ground lug on the arrestor is designed for #2AWG solid or stranded wire. The ground wire must be crimped to this lug, never soldered. Caution The lightning arrestor must be connected to an earth-ground. The top and bottom ends of the coaxial cable attached to the tower should be electrically grounded with kits for lightning protection. The antenna input connection cannot serve as the top ground point. For cable lengths in excess of 200 feet, ground the vertical cable run every 100 feet. Note The installer must supply any mounting brackets and cable-management clips to secure the coaxial cable to the tower or structure, when using a remote/external antenna. Consult your cable manufacturer for specifications on proper clips and grounding kits. Conduit clamps and tie wraps are not satisfactory methods for securing coaxial cables. For a remote 900 MHz installation with a high gain antenna, a lightning arrestor is supplied by Itron in the CCU 100/Repeater 100 kit materials.
AC Mains Power CCU 100 and Repeater 100 Installation Guide 13 Proprietary and Confidential AC Mains Power The AC mains wiring to the CCU/Repeater utilizes a three conductor cable. This cable can be terminated with either a NEMA L5-15 (125V, 15A) or a NEMA L6-15 (250V, 15A) locking plug in order to meet local electrical codes. The CCU should be powered by a dedicated 10A circuit. The CCU/Repeater should not be connected to a circuit protected by a GFCI breaker. Power wiring on the Itron supplied power cable follows conventional color coding for AC wiring: Green/Ground, White/Neutral, Black/Hot. Warning The CCU/Repeater must be grounded by using either the ground wire in the three conductor cable or the grounding lug on the bottom of the CCU/Repeater. For installations that use the photocell adapter the grounding lug must be used to ground the CCU. DC Mains Power The DC wiring to the CCU/Repeater utilizes a two conductor cable. The CCU should be connected to a 10A DC circuit breaker or fuse. Wiring of the Itron supplied two conductor cable is accomplished by attaching the red wire to a +12V source and attaching the black wire to ground. Materials Not Provided by Itron The following materials are not provided by Itron in the CCU/Repeater kit, but are required for installation. Please acquire these items prior to beginning an installation. • Coaxial cable on page 13 (for remote/external antennas) • Connectors on page 15 • Mounting hardware on page 15 Coaxial Cable When mounting the remote/external antennas, coaxial cable must be supplied to connect the antenna to the CCU/Repeater. The proper size of cable is dependent on total cable length and frequency. Coaxial cable also requires proper hoisting grips, ground kits, connectors, jumpers, hangers, and weather proofing material. Coaxial cable and accessories are not provided by Itron. Coaxial cable systems must be installed according to the manufacturer's specifications. Itron recommends using qualified radio installation contractors to install the remote/external antenna system. Remote Mount 900 MHz Antenna on a Standard CCU/Repeater When selecting cable for the remote mount 900 MHz antenna on the standard (non-tower) CCU/Repeater, total cable loss cannot exceed 1.5 dB to maintain system performance. Allow 0.1 dB loss for each connector.
Chapter 2 Planning a CCU/Repeater Installation 14 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential Remote Mount High Gain (8.15 dBi) 900 MHz Antenna on a Tower CCU The table below lists several options for coaxial cable that can be used with the remote mount high gain 900 MHz antenna. when installing the high gain antenna on a Tower CCU the FCC has set limits to the maximum transmit power of the CCU. In order to meet these limits, Tower CCUs with FCC ID number EO9CCU100T must have a minimum of 2.2 dB worth of loss (but not more than 3.5 dB) between the tower cabinet and the antenna. All other tower CCUs should be installed with minimum cable loss. Allow 0.1 dB loss for each connector. If required, a 1 dB attenuator (similar to the Pasternack PE7002-1) may be used to attain the desired power at the antenna. Total Coaxial length Coax specification 0-120 ft. 121-200 ft.

CCU 100 and Repeater 100 Installation Guide 49 Proprietary and Confidential In this chapter, you will learn how to perform field maintenance on the CCU/Repeater battery. With some routine care, the batteries used by CCUs/Repeaters will perform at optimal levels for several years. The following sections show you how to store and charge spare CCU/Repeater batteries, as well as how to replace a CCU/Repeater battery in the field. Shipping Requirements Warning! Electrical fire hazard—protect against shorting. Terminals can short circuit and cause a fire if not insulated during shipping. Requirements for shipping batteries: • Batteries must be labeled "NONSPILLABLE" during shipping. Follow all federal shipping regulations. See CFR 49 Parts 171 through 180, available online at www.gpoaccess.gov • Batteries must have short circuit protection during shipping. Exposed terminals, connectors, or lead wires must be insulated with a durable inert material to prevent exposure during shipping. Failure to comply with these requirements can cause a fire during shipping and handling. CHAPTER 4 Battery Care and Replacement
Chapter 4 Battery Care and Replacement 50 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential Battery Storage and Charging To ensure maximum lifespan and efficiency from your CCU/Repeater batteries, Itron recommends the following storage and maintenance procedures. Long-Term Storage Batteries may be stored for up to two years at room temperature (25°C or 77°F), and then may be recharged with no loss in cell reliability or performance capabilities. The example storage time versus temperature chart below is a plot of maximum storage time as a function of storage temperature. This curve shows the maximum number of days at any given temperature, from 10°C (50°F) to 65°C (149°F), for the battery to discharge from a fully charged state of about 6.42 volts (2.14 volts per cell) down to a zero charge state of 5.79 volts or (1.93 volts per cell). The battery should not be allowed to discharge below 5.79 volts because of the danger of damaging the performance characteristics of the battery permanently. When batteries are stored at or near 25°C (77°F) it is recommend to conduct an open circuit voltage (OCV) audit every six months and recharge when OCV readings approach 6 volts (2.00 volts per cell). If storage temperatures are significantly higher than 25°C (77°F), even for short durations, the frequency of OCV audits must increase. It is important to recognize that the self-discharge rate of the battery is non-linear. The rate of self-discharge changes as the state of charge (SOC) of the battery changes. The time taken for a battery to discharge from a 100% SOC to 90% SOC is different from the time it takes to self-discharge from a 20% SOC to a 10% SOC.
Battery Storage and Charging CCU 100 and Repeater 100 Installation Guide 51 Proprietary and Confidential State of Charge The state of charge (SOC) of the battery can be approximated by using the curve shown in the chart below. This curve is accurate to within 20% of the true SOC of the cell under consideration, if it has not been charged or discharged within the past 24 hours. The curve is accurate to within 5% if the cell has not seen any activity, charge or discharge, for the past five days. Charge the Battery You can charge spare CCU/Repeater batteries individually or in groups to save time. When charging batteries, there are several items you need: • Power Sonic PSC-61000A-C charger • Molex 39-01-4046 connector • CCU/Repeater batteries The recommended method for charging the batteries is to utilize the Power Sonic PSC-61000A-C charger. The Power Sonic charger needs to be modified so that it can be plugged directly into the battery. This is done by retrofitting the output of the charger to a Molex 39-01-4046 connector with the red wire going to pin one and the black wire going to pin two of the connector. Follow the instructions that come with the charger for correct operation. After charging, the battery should be removed from the charger for at least 24 hours. After this time the open circuit voltage should be measured to verify that it is at or above 6.4 volts. Note Batteries in storage need to be charged routinely for maximum shelf life. For more information, see Long Term Storage on page 50.
Chapter 4 Battery Care and Replacement 52 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential Battery Service Life All batteries have extremely variable service life, depending upon the type of cycle, environment, and charge to which the cell or battery is subjected during its life. There are two basic types of service life: cycle life and calendar life. The battery in the CCU/Repeater is called in to service only during power outages, so in this case only calendar (or float) life is applicable. Calendar Life The design calendar (or float) life of the battery is up to eight to ten years at room temperature (25°C/77°F) and under proper charging conditions. This design life has been confirmed by the use of accelerated testing methods that are widely accepted by both manufacturers and users of sealed-lead batteries. High temperatures are used to accelerate the aging process of the battery under test. The float life of a cell is cut in half for roughly every 8°C (14.4°F) rise in ambient temperature. The example below shows the relationship between ambient temperature and float life for batteries that have a float life of ten years at 25°C (77°F). A ten year battery lasts for five years at 33°C (91.4°F) and only 2½ years at 41°C (105.8°F). Preventative Maintenance Itron recommends a preventative maintenance cycle of a two-year replacement in extreme environments (average temperatures greater than 110°F/44°C), or five years in non-extreme environments (average temperatures less then 90°F/31°C).
Replacing the Integrated Battery CCU 100 and Repeater 100 Installation Guide 53 Proprietary and Confidential Replacing the Integrated Battery The following procedure shows you how to replace the integrated battery once it has been installed in the field.

CCU 100 and Repeater 100 Installation Guide 63 Proprietary and Confidential Status Indicator The LED Status Indicator is primarily intended to support installation personnel for immediate feedback. The following sequences define the Fixed Network solution's operational characteristics: Sequence details: The dot time: 100 mSec The dash time is 300 mSec Off Time between B and N: 700 mSec Off time between dot and dash: 100 mSec CCU State Description LED Pattern Off The CCU is not running Off Powered (Host booting) When power has been applied to the CCU and the CCU reset has been released allowing the boot operation to begin. Solid continuous illumination Time Acquisition The CCU is attempting to synchronize its system time with an external time reference through NTP and / or GPS. Note Repeaters do not support NTP. Instead, repeaters acquire time from either the CCU or from GPS. If time is received from the CCU, the repeater status indicator will not display the Morse T. Morse code for the letter ‘T’ ( _ ). A single 660 ms flash repeated every 10 seconds. Starting The Linux kernel has been loaded and initialized and the CCU application begins execution Morse code for the letter ‘P’ ( . _ _ . ) with the dits at 220 ms the dahs at 660 ms and 220 ms spacing between the dits and dah. Repeated every 10 seconds. ERT Heard The radio processor has booted and is reporting end-point messages to the host processor Morse code for the letter ‘N’ ( _ . ) Headend Connected The CCU has established an authenticated connection with the head-end over the configured WAN interface. Morse code for the letter ‘B’ ( _ . . . ) No Battery The CCU has determined that it should have a backup battery but that battery does not appear to be present or is not functioning. The display of this state is a higher priority than states other than Low-visibility and will be displayed exclusively if the battery cannot be detected. Morse code for the letter ‘S’ ( . . . ) APPENDIX B Status and Diagnostics
Appendix B Status and Diagnostics 64 CCU 100 and Repeater 100 Installation Guide Proprietary and Confidential CCU State Description LED Pattern Ok The radio processor has booted and is reporting end-point messages to the host processor and the CCU has established an authenticated connection to the head-end. This condition will be signaled for about 15 minutes before moving the "low-visibility" state. Morse code for the letter sequence ‘BN’ ( _ . . . _ . ) The dit and dah timing described above with the space between the ‘B’ and the ‘N’ characters being 660 ms. Token Received If the radio reports decoding a "magic" token which would enable the WiFi diagnostic interface this pattern is presented for one 10 second interval. This condition is higher priority than the Lo-visibility and the missing battery indications. Morse code for the number ‘5’ ( . . . . . ). Low-visibility After 15 minutes in the "Ready" state the LED pattern changes to the "Low-visibility" mode which indicates that the CCU is running (does not imply that end-points are still being read or that head-end communications are still possible. 10 ms illumination every 30 seconds. Performing an Antenna Sweep Test If the 900 MHz antenna is remotely mounted for your installation, an antenna sweep test must be performed to verify that the antenna functions within acceptable tolerances at your installation site. This test should be performed under the following conditions: • Beginning Frequency: 902 • Ending Frequency: 928 • VSWR Expected Results: Must be 1.5 or less for the specified frequency band. • Return Loss: Must be –18dB or better for the specified frequency band. Any deviations from this return loss warrant further investigation. • Test Point: Feed line connected to the antenna at the top; test from the lightning (or surge) arrestor to the antenna port. • Results: Test results must be saved in. PDF format. • Test Gear: Current and proper calibration; be sure that calibration is turned on during the test. A qualified operator of the test equipment must perform the test. Note If the system does not perform to the above test specifications, the reasons for system failure and possible remedies must be identified before leaving the installation site.
