UNPACKING
Each major component of the TTA system is indi-
vidually packaged and shipped via motor freight or
UPS. It is important to report any visible damage to
the carrier immediately. It is the customer's respon-
sibility to file damage claims with the carrier within
a short period of time after delivery (1 to 5 days).
PRE-INSTALLATION CHECKOUT
The following pre-installation tests should be per-
formed after unpacking the system to verify nothing
has loosened during transit. Additionally, the sys-
tem should be made operational on the bench with
all components at ground level to verify proper
electrical performance. Figure 3 illustrates all of
the cable connection points for both the tower top
box and the MCU.
The tower top box should NOT be
installed on the tower until all of the
pre-installation tests are successfully
completed.
Mechanical Inspection
