        (7) Output Terminals and Slave Receptacle.  The output 
terminal board and ground terminal are located on the generator 
set skid base, just below the control box assembly.  A hinged 
cover (16, Figure 1-2) allows access to the three load terminal 
and single ground terminal.  An insulated wrench, used for 
connecting wires to terminals, is secured to the rear of the 
hinged cover.  A filter mounted to the back of the load 
terminals prevents Electro-Magnetic Interference (EMI).  The 
generator’s 24VDC slave receptacle is mounted to the skid base, 
to the right of the output terminals. 

                 

 

        (8) Engine/Generator Assembly.  The engine/generator 
assembly (Figure 1-3) consists of a single-cylinder engine (14), 
permanent magnet generator (5), and associated electrical, fuel 
and oil components,  The engine/generator assembly is mounted to 
the skid base (8) with vibration mounts (7) to prevent engine 
vibration from affecting the operation of the generator set 
components.  A fuel drain plug (9) and oil drain plug (10) allow 
maintenance to drain engine fluids.

 Electrical high voltage cannot be seen but it can kill you, 

render you unconscious, or severely burn you. Failure to 

observe safety precautions may result in serious injury or 

death.
