Proprietary and Confidential
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 at
the midpoint and then each additional 200 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 mount
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 remote installation with a high gain antenna, a lightning arrestor is supplied by Itron in
the CCU 100/Repeater 100 kit materials.

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.

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.
