A short-duration surge, due to transformer inrush current, will
occur at turn-on or during a short AC power loss. This surge can
be as high as 400 amps. During this surge, the line voltage at the
cabinet must not drop below 80% of the rated line voltage. Select
a 40 amp breaker or fuse for the transmitter using the above
inrush current information.
2.3.3
AC mains Disconnect Location
The circuit breaker panel should be located near the transmitter
in a well lighted area. As a safety precaution, controls for
disconnecting the main power service supplying the transmitter
must be convenient to the operator and maintenance personnel.
Breakers must be clearly labeled. Provisions for emergency
lighting should be made.

Unloading and Unpacking
2.4.1
Equipment Required for Unloading
Examine the weights listed on the Transmitter Outline drawing
for guidance on the equipment needed. Note: The notch
diplexer, if used, will be the heaviest.
2.4.2
Unpacking, Equipment Inventory and Inspection
A “check-off” box is available to help the installer track the steps
that have been completed.
When the transmitter is delivered to the site, the shipment should
be inspected and inventoried before installation is begun. This
section provides information to assist unpacking and inventory.
Locate the packing check list when the shipment arrives.
Each transmitter shipment will be accompanied by a packing
check list identifying which equipment is packed in the various
crates and boxes.
LOCATED PACKING CHECK LIST
The contents of the shipment should be inventoried with the
packing list. Carefully unpack the unit and perform a visual
inspection to determine if any apparent damage has been in-
curred during shipment. Retain all shipping materials until it has
been determined that all items on the list are on site and no
damage occurred during shipment. It may be necessary to search
packing material for parts initially missed during unpacking.
The carrier may also wish to examine the packing material.
If the contents are incomplete, or if the unit is damaged electri-
cally or mechanically, notify the Harris Customer Service De-
partment by phone at 217-222-8200, FAX at 217-222-9443 or
