1 Center the crimps.
Crimps may be off-center, but not off the end of
the wire barrel.
2 Ensure the AWG wire size you are using
matches the wire range or size stamped on the
terminal or the splice and dies.
3 Ensure the insulation does not enter the wire
barrel.
4 Ensure the wire is visible through the inspection
hole of the butt splices. The wire must be flush
with or extend slightly beyond the end of the
terminal wire barrel.
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: When a remote/external antenna is used, the installer must supply any mounting
brackets and cable-management clips to secure the coaxial cable to the tower or structure.
Consult your cable manufacturer for specifications on proper clips and grounding kits.
Conduit clamps and tie wraps are not satisfactory methods forsecuring coaxial cables.
For a remote 915 MHz installation with a high gain antenna, a lightning arrestor is supplied by
Itron in the CCU 100 or Repeater 100 kit materials.
AC Mains Power
The AC mains wiring to the collector or repeater utilizes a three conductor cable. Terminate this
cable with either a NEMA L5-15 (125V, 15A) or a NEMA L6-15 (250V, 15A) locking plug to meet
local electrical codes. The collector or repeater must be powered by a 90-265 VAC source
defined as a maximum 15 amp branch circuit and must be protected by a certified branch circuit
breaker. TCU 100s require a minimum 15 amp 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. Power wiring on the Itron-supplied power
cable follows conventional color coding for AC wiring: green (ground), white (neutral), black
(hot).
Warning !
Securely mount the collector or repeater before connecting the dedicated
AC mains power source.
You must ground the collector or repeater by using either the ground wire in the three
conductor cable, or the grounding lug on the bottom of the collector or repeater. For
installations that use the photocell adapter, the grounding lug must be used to ground
the CCU.
