The CCU 100 (also known as a cell control unit or collector) is the main collection point for the ChoiceConnect Fixed Network. The CCU reads data from Itron electricity meters, gas endpoints, and water endpoints and gathers consumption, daily, or hourly meter reads, and other information from endpoints and communicates it back to the utility over a public or private network.

Page 61: Battery Care And Maintenance
Battery Storage and Charging To ensure maximum lifespan and efficiency from your collector or 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.
Page 62: State Of Charge
Chapter 4 Battery Care and Maintenance Itron recommends you conduct open circuit voltage audits every six months on batteries stored at or near 25°C (77°F). Recharge batteries when OCV readings approach 6 volts (2.00 volts per cell). Increase OCV audits if storage temperatures are significantly higher than 25°C (77°F)—even for short durations.
Page 63: Battery Service Life
Battery Service Life The charging of collector and repeater batteries requires the following items: • Power Sonic PSC-61000A-C charger • Molex 39-01-4046 connector • Collector or repeater batteries The recommended method for charging batteries is to utilize the Power Sonic PSC- 61000A-C charger.
Page 64: Preventative Maintenance
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 than 90°F/31°C).

Reducing the Ohms level In many areas of the country you may be starting with 350 Ohms or more. Itron’s networks are built all over the United States and the geological features can vary greatly in different parts of the country; therefore, allow the installing contractor to determine how best to lower resistance to ground (to 5 Ohms or less) in a specific region.

Page 104: Adjusting The Routing Of The Grounding Conductor
Appendix F Grounding Specifications Meggers come in three and four terminal configurations. To test the actual resistivity of the soil itself, use a four terminal model. The advantage of this method is that you are not connected to the electrical system during testing. An electrical line fault during testing can send high current to the grounding system, resulting in high current and voltage at the test leads and meter.

TCU / CCU on a Steel Frame or I-Beam or Platform If the Itron TCU / CCU equipment is mounted on a steel frame or I-beam, bond the steel to the BGR at opposite ends with two No. 2 AWG BTCW and exothermically welded at each end.

Grounding Specifications In this configuration, the MGB is typically used for Itron TCU / CCU equipment, coax cable, and platform grounding. 4. Mount the MGB so that all equipment, coax, and platform ground lugs attach to the top two rows of holes and the leads connecting to the BGR attach to the bottom two rows of holes.
Page 115 Sample Sweeps Output • At the bottom of a tower on page 107 • At the end of an ice bridge on page 107 • With GPS and WAN antennas on page 108 • Grounding a coax ground kits on page 108. To install coax ground kits at the top of a tower Install one CGB at the top of the tower as close as possible to the tower top coax ground kits.
Page 116 Grounding Specifications To attach a coax ground kit at GPS and WAN antenna If the GPS and WAN antennas are mounted on the monopole or antenna support structure, attach a coax ground kit to the coax as close as possible to the antenna and connected to a small CGB.
Page 117: Collector Sites With Indoor Itron Tcu / Ccu Equipment
Sample Sweeps Output Collector Sites with Indoor Itron TCU / CCU Equipment When grounding equipment for collector sites where the Itron TCU / CCU equipment is located indoors include the installation on an interior ground ring (halo) installed approximately 6 inches below the ceiling or 8 feet above the finished floor, whichever is lower.
Page 118 Grounding Specifications To work with interior connections 1. Connect all grounding and bonding conductors that are connected above grade or interior to a building using two-hole multiple crimp type (with UL tool and circumferential die compression) connections or by exothermic weld connections where allowed.

Do not use AC service panel grounds. 3. If the Itron TCU / CCU equipment is located on the ground floor or in the basement, the MGB may be connected directly to both building steel and the water main or ground rod.

3. If the Itron TCU / CCU equipment is located on the ground floor or in the basement, the MGB can be connected directly to both the existing lightning protection or building ground system and the water main or ground rod.
Page 121: Cold Water Pipe Option
Sample Sweeps Output A low halogen cable that meets the ratings of Telcordia GR-347 is acceptable. Place the MGB bar as close as possible to the equipment cabinets and the path to ground options (for example, ground rod, cold water pipe, or building steel). Install the ground bar to ensure that the wire bending radii for the 4/0 AWG and No.
Page 122: Cable Tray Grounding
Grounding Specifications Grounding antennas on rooftops 1. Bond each antenna mount/mast to the CGB with No. 2 AWG BTCW exothermically welded to the mast and connected to the ground bar with an approved two- hole ground lug. 2. Install coax ground kits as close to the antennas as possible, just before the antenna jumpers, and then bonded to the CGB.
Page 123: Water Tower Grounding
Itron does not construct water towers. Therefore, network devices utilizing water towers as antenna structures do not require the installation of a structure ground ring around the leg of a water tower. The equipment BGR serves as the primary ground point for all Itron equipment, antennas, coax, and cable tray.
Page 124: Equipment Shelter Grounding
Equipment Shelter Grounding Ground Itron equipment that is installed in shelters the same way you ground a non- shelter site in terms of equipment ground leads, coax ground kits prior to the Itron TCU / CCU equipment jumpers, and MGB placement.
Page 125: Repeaters On Rooftops
Sample Sweeps Output 4. Bond the CGB to a single ground rod located immediately adjacent to the support structure using No. 2 AWG BTCW. Note In all cases, ensure that the grounding design complies with the utility pole owner’s requirements. Repeaters on Rooftops Repeaters located at rooftop sites must have antenna mounts, coax, and coax cable tray (if required) grounded in the same manner as a full network device.
Page 126: Cable Entrance Facilities
Grounding Specifications AC Power Grounding Connections In accordance with the National Electric Code, Article 250 or appropriate local codes, bond the AC power neutral to the Master Ground Bar (MGB-1) Producer (P) section. Refer to Section 3.2.1 of NP-312-202, Interior Grounding System Design, for more information.
Page 127: Clamp-On Ground Resistance Testing
Sample Sweeps Output Clamp-On Ground Resistance Testing A clamp-on ground resistance tester measures ground rod and small ground grid resistance without the use of auxiliary ground rods. Clamp-on ground resistance testers are used in multi- grounded systems without disconnecting the ground under test and with electrical service connected.
Page 128: Determining The Correct Measuring Point
Grounding Specifications The following illustration shows a Principle of Operation. Determining the Correct Measuring Point The preferred point of measurement (if internal bonding allows) is on the conductor between the ground bus and the service neutral. If internal bonding does not allow access to this point, an alternate point is on the service side of the neutral line prior to the neutral to ground bond.
Page 129: Testing Procedures
Sample Sweeps Output The following illustration shows an overview of the testing location. Testing Procedures To prepare the meter 1. Ensure mating surfaces of the jaws are clean and free of corrosion. 2. Press and hold the ON/OFF button for approximately 3 seconds. 3.
Page 130: Understanding Party Responsibilities
The Supplier should expect that representatives from both Itron and the Customer will be on site at several installations of each type of network device (if not more), to ensure the installations meet the Itron and Customer quality and design requirements.
