1.11.1 Basic Power Plant III.
1.11.1.1 Pallet Frame.
The Electric Power Plant III consists of a pallet frame (7, figure 1-2) on which all components are
mounted. The pallet frame consists of a welded aluminum honeycomb frame, three lifting, and two
forklift sockets for transportation and installation or removal onto or from the truck chassis. The
pallet frame also has eight bolt mounting points with recesses, into which the two Generator Sets
150 kW (1) are bolted. Toward the front is a closable enclosure housing the four exhaust hoses (13).
On the right side are a total of five cable drums (8,9). The four power cable drums (9) can be swung
out 90” and locked in place. A power distribution unit (2) is also mounted. An enclosure housing the
grounding rod (6) is welded onto the rear of the pallet frame. Once disassembled, the grounding rod
can be placed in this enclosure and secured with a bolt closure. The sling assembly (6), folded up
and secured with two straps, is also located at the rear of the pallet frame. ‘Iwo fire extinguishers
(11,12) are mounted on the left side. The pallet frame can be placed on the truck chassis, using four
tightening assemblies (10) that are secured with bolts. The mounting assemblies include shock
absorbers.
1.11.1.2 Power Distribution Unit.
The power distribution unit (2) consists of a cabinet housing with an access door. A swing-out
control panel (14) is located on the door. The cabinet door can be secured in the open position with
prop. The power distribution unit contains all the electrical equipment, consisting of power
contactors, auxiliary relays, time relays, and electronics groups. All connecting lines are installed in
cable conduits, and emerge at a connection panel (16). All Electric Power Plant III connections are
made through this panel. The power distribution unit is mounted on the pallet frame (7) on four
shock absorbers.
A grounding connector (16) and a grounding bar (17) are installed on the power distribution unit for
the connection of grounding cables (3,4).
1.11.1.3 Generator Sets 150 kW.
The Generator Sets 150 kW (1) are each secured on the pallet frame (7) with four eyebolts and are
connected to the pallet frame with a grounding cable. Connection to the power distribution unit (2)
is made with power cables which are attached on the power distribution unit.
1.11.1.4 Cable Drums.
The four power cable drums (9) remain in the stowed position for transport or when not in use, and
are swung out 90” for operation. They lock into place in both positions. The cable, approximately 95
ft (29 m) long, is unreeled for operation. The drums contain a tension mechanism with lock, that
continuously ratchets as cable is unreeled or wound in. The control cable drum (8) does not swing
out. The cable, approximately 104 ft (32 m) long, is unreeled for operation.
