To avoid 
an 
overcharging condition, and a possible equipment failure, do not disconnect 
tbe DC battery source while tbe engine is running. 
Automatic 
Shutdown 
High Exhaust Temperature Shutdown Switch (normally closed) 
An exhaust temperature is located on the exhaust elbow. 
Should tbe switch's sensor indicate 
an 
excessive 
exhaust temperature, tbe switch will open and shut tbe generator off (an inadequate supply 
of 
raw water 
coolant causes  high exhaust temperatures).  This switch opens 
at 
260  - 270°F (127 - 132°  C)  resets 
at 
approximately 225°F (107°C). 
High Water Temperature Shutdown Switch (normally closed) 
A high water temperature switch is located on tbe thermostat housing. 
Should the fresh  water coolant's 
operating temperature reach approximately 
205° F (96°C), the switch will open 
and 
shut 
the 
generator 
off. 
This switch resets 
at 
195°F (107°C). 
Low Oil Pressure Shutdown Switch (normally open) 
A low  oil pressure shutdown switch is located off tbe engine's oil  gallery.  The switch's sensor monitors 
tbe engine's oil  pressure.  Should the engine's oil pressure fall to 5 -
10 
psi, the switch will open 
and 
turn 
the generator off. 
Generator 
(AC 
Output) 
Make sure tbat tbe AC output connections within tbe generator's AC terntinal block are correct 
and 
in 
accordance witb the specific  AC  Load Connections diagram found later in this  manual.  (See tbe "BT 
GENERATOR" section 
of 
tbis manual.)  Make sure tbe AC leads are protected against chafing as they 
exit tbe generator housing. 
I WARNING  I 
Do not smoke or allow an open flame near batteries.  Lead acid batteries emit hydrogen, 
a highly-explosive gas. 
Batteries 
Make sure  tbe positive (+)  battery connection  is  connected 
to 
the  battery connection 
of 
tbe  starting 
solenoid.  The negative (-) battery connection should be connected to the ground stud tagged 
at 
the rear 
of 
the engine block.
