Siting Collectors or Repeaters
TDC-0971-011 CCU 100 and Repeater 100 Installation Guide 9
Proprietary and Confidential
• 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).
Note Typically, maintaining a 10-foot vertical separation from other transmitters
allows for a co-location type of installation.
• 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 (an antenna will not communicate if it is surrounded by
metal) or inside a building. The collector or repeater can be installed in a building or
other metal enclosure, but the antennas must be installed externally.
Warning Before installing a collector or 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
The collector or repeater must be powered by a 90-265 VAC source defined as a
maximum 15 amp branch circuit (a minimum 15 amp branch circuit for TCU 100s), and
the collector or repeater must be protected by a certified branch circuit breaker. Do not
connect the collector or repeater to a circuit protected by a GFCI breaker. Size the wiring
in accordance with the National Electrical Code, ANSI/NFPA 70 and, where applicable,
the Canadian Electrical Code, Part I, CSA C22.1 or the prevailing local code. For more
information on these options, see AC Mains Power on page 13, DC Mains Power on page
14, or Solar Powered Installation on page 45.
External Ethernet Connections
If the Ethernet is used as the communications backhaul, the collector installation site must
have Ethernet access. Also, be sure to use weatherproof cables in this type of installation.
If the collector is not on the same subnet as the database server, additional network
configurations are necessary. See Port and Protocol Requirements on page 67. Network
functionality, specifically on-demand reads, adaptive channel planning, list management,
and endpoint type exclusion, are affected if the database server cannot initiate
communication to the collector.
Caution If you use Ethernet as the communications backhaul, the collector must
be identified as Ethernet-based when performing the initial collector configuration.
Failure to identify the collector as Ethernet-based prohibits the collector from
communicating with the Network Collection Engine.
