High Voltage Hazards:
The TWTA utilizes high voltage that can be lethal if contacted. The
TWTA should not be operated without its cover unless the user is
thoroughly familiar with its operation and experienced with high
voltage.
RF Radiation Hazards:
Prior to operation of the TWTA, ensure that all microwave connections
are securely fastened. Check that there is no microwave leakage from
them. Never operate the TWTA with an open waveguide. This amplifier
is capable of generating high power microwave radiation, which can
cause bodily harm.
Safety Summary:
Equipment of this nature has inherent hazards. Operator or service
technicians should have training on the TWTAs. When the TWTA’s
cover is removed, the high voltage power supply for the TWT has
multiple exposed high voltage points. Use extreme care when operating
the amplifier with its cover removed.
3.1 Unpacking
The redundant TWTA assembly is shipped as a unit in one crate.
Before unpacking the carton components, ensure that there is plenty of room around the
carton for workspace. A large table is recommended.
To remove the parts:
1. Remove the screws from the lid of the wooden crate, and remove the lid.
C AU TIO N
Because the redundant TWTA assembly is heavy, assistance may be
necessary to remove the unit from the box.
2. Unbolt the TWTA assembly and remove it from the crate.
3. Remove the remainder of the parts from the crate. Refer to Section 3.2.1 for a
parts breakdown.
Note: Save the packing material for reshipment.
