Installation Considerations
ERT Compatibility
The CCU4 collector reads the following types of Itron ERTs and messages:
•25Series
•40Series
•41Series
•45Series
•50W
• SSD (Solid State Demand ERT)
• SCM and IDM messages- IDM first priority
Collector to ERT Ratio and Distance
Although the CCU4 collector potentially can read many more ERTs, to ensure all data is
collected, place one collector for every 100 unique ERTs.
The collector reads ERTs within a maximum radius of 800 ft, although some environmental,
weather, and terrain conditions can affect this distance.
Radio Frequency
To ensure RF signals are received, install the collector at elevations and locations where the
greatest number of endpoints are in direct line of sight of the collector.
Avoid installing collectors in following ways:
• Adjacent to or between tall buildings, signs, towers, or bridges
• Within 500 ft of high power 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
and neon or fluorescent signs)
• Near swaying limbs, branches, or cables that could strike the collector
• Between or beneath highway overpasses, elevated train platforms, or tunnels
• Near tunnel entrances
• Near objects or devices (such as solar panels and signs) attached to the same pole
