CCU/Repeater Basics
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.

CHAPTER 2
Planning a CCU/Repeater Installation
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
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.
CCU 100 and Repeater 100 Installation Guide
Proprietary and Confidential
Siting CCUs/Repeaters
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 43.
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
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 remotemounted 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
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
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

AC Mains Power
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.

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

External GPS and WAN Antennas
The primary requirement for any coaxial cable used with the external GPS or WAN
antenna is to have less than 5 dB of attenuation at 1.5 to 1.8 GHz for the entire length of
cable, including connector losses.
You may use any type of 50 ohm coaxial cable, as long as the total loss, including
connectors is less than 5 dB at 1.5 to 1.8 GHz.
If you are using coaxial cable larger (or stiffer) than 1/2 inch superflex, add a short (less
than 5 feet) piece of LMR 400 cable to each end before connecting the cable to the CCU
and the antennas. Use the appropriate connectors between the LMR 400 and larger
coaxial cable.
If the antennas are mounted in an exposed outdoor environment, you must provide
lightning protection and proper grounding. For more information on lightning protection
and grounding, see Lightning Arrestor on page 12, Grounding the Remote/External
Antenna Systems on page 11 and the Motorola R-56 guidelines.

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
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 PSC61000A-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 48.

Battery Care and Replacement
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 nonextreme environments (average temperatures less then 90°F/31°C).

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.
