THEORY OF OPERATION
After the shelter has been erected, the operator personnel will unbolt selected items of equipment. (See
WP 0002 00, Figure 2). These items will
to pre-selected positions
on the expanded side
shelter. (See WP 0002 00, Figure 3). The selected items, when moved, will not be secured (bolted) in place. This
allows the shop personnel a certain flexibility in the event long or bulky materiel must be repaired within the
shelter. The recommended locations were selected for proper utilization of floor space and maximum safety for
the operating personnel.
Four people are needed when moving or lifting the ECUs. Each unit weighs
approximately 270 pounds. Trying to move or lift an ECU without sufficient help
can cause SERIOUS INJURY to personnel.
Detailed instructions for unbolting equipment and the recommended sequence for relocating equipment are
contained in WP 0008 00. The procedures for striking the shelter and preparing Composite Shop for transport or
Permanently installed equipment or components should not be removed. If hardware is damaged and it is
necessary to remove, reinstall, or replace fixed equipment or shop components within shelter, care must be taken
to remove all bolts, nuts, and other fasteners. All cabinets and racks are bolted to floor and unless isolated, are
normally bolted to adjacent cabinets and/or to wall and ceiling.
The ECUs are supplied by the unit. Procedures for positioning the ECUs for operation are in WP 0007 00. The
two ECUs are positioned on special fold-down panels when the shop is in the operational mode. Power is
provided by a 208V, 3 phase cable located inside the shelter next to each panel. Both ECUs can be easily
removed for service or repair. Procedures for repositioning the ECUs for transport or storage are in WP 0013 00.
Electrical power to operate the Composite Shop is provided by an auxiliary generator or a commercial power
source. A Power Distribution Box (PDB) is used between the power source and the power entry panel of the
shelter. The generator, PDB, and the pigtail used to connect the PDB to the generator are supplied by the unit.
Overload protection is provided by circuit breakers. The circuit breaker panel is located inside the shelter next to
the personnel entrance door. Procedures for connecting electrical power to the shop are in WP 0006 00.
Procedures for disconnecting electrical power from the shop are in WP 0014 00.
