3.2 Unpacking the Cabinets
Note: Air conditioning and any
related heat exhaust ducts should be
in place before continuing with the
installation of the transmitter.
Thoroughly inspect the cabinet and all
other materials upon their arrival. Axcera
certifies that upon leaving our facility the
equipment was undamaged and in proper
working order. The shipping containers
should be inspected for obvious damage
that is indicative of rough handling.
Check for dents and scratches or broken
switches, meters, or connectors. Any
claims against in-transit damage should
be directed to the carrier. Inform Axcera
as to the extent of any damage as soon
as possible.
Remove the cabinet with trays, UHF tee
assembly, bandpass filter, digital
modulator, (optional) trap filter,
directional coupler, and the installation
material from the crates and boxes.
Remove the straps that hold the cabinet
to the shipping skid and slide the cabinet
from the skid. Remove the plastic wrap
and foam protection from around the
cabinet. Do not remove any labeling or
tags from any cables or connectors;
these are identification markers that
make assembly of the transmitter much
easier.
Remove the four L-brackets, mounted on
the front panel rails, which held the trays
in place during shipment. The trays are
mounted in the cabinet using Chassis
Trak cabinet slides. The tray slides are on
the top and bottom of the UHF amplifier
trays and on the sides of the UHF exciter
and digital modulator trays. Inspect the
trays for any loose hardware or
connectors, tightening where needed.
Open the rear door and inspect the
interior for packing material, carefully
removing any that is found. Slowly slide
each tray in and out to verify that they
do not rub against each other and have
no restrictions to free movement.
