CCU Installation Wiring Diagram
Tower Installation
Warning Before installing a Tower CCU, ensure that the selected location can
support the weight of the Tower CCU and mounting hardware. A thorough
structural analysis should be performed by a registered professional engineer at
location prior to installation. Itron is not responsible for improper installations or for
installations at a site that cannot adequately support the Tower CCU.
You must use 3/8–16 bolts to secure the enclosure to the pierced and slotted metal
brackets.
All coaxial cable connections must be properly weather-proofed per industry standards
unless otherwise specified. This includes any connections for the antennas and the Tower
CCU. If the Tower CCU is installed indoors, only the connections located outside must be
weather-proofed.
Important To prevent exceeding the maximum EIRP set by the FCC, there must
be at least 2 dB of loss between the antenna connector at the base of the tower
cabinet and the high gain 900 MHz antenna. Do not exceed 3.5 dB of loss to
maintain system performance. Only use the Itron-approved high gain antenna.
