The ground lug is manufactured by AMP/Tyco Electronics (part number 320754) and is
designed for #2 AWG solid or stranded wire (0.257-inch to 0.335-inch diameter). The lug
must be properly crimped (never soldered) to the wire using SOLISTRAND tooling
designed for the lug. The following figure details a proper crimp.

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 for
securing coaxial cables.

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.
