12 Owner’s Manual for 60 Hz Air-Cooled Generators
Protection Systems
The generator may need to run for long periods of time 
with no operator present to monitor engine or generator 
conditions. The  generator is equipped  with  protection 
systems  to  automatically  shut  down  the  unit  to  protect 
against  potentially  damaging conditions.  Some of  these 
systems include:
Alarms:
• High Temperature
• Low Oil Pressure
• Overcrank
• Overspeed
• Overvoltage
• Undervoltage
• Overload
• Underspeed
• RPM Sensor Loss
• Controller Fault
• Wiring Error
• Stepper Overcurrent
Warnings:
•  Charger Warning
•  Charger Missing AC
•  Low Battery
•  Battery Problem
• Exercise Set Error
• USB Warning
• Download Failure
The control panel contains a display alerting the operator 
when  a  fault  condition  occurs. The  above  list  is  not  all-
inclusive.  See  Operation  for  more  information  about 
alarms and control panel operation.
NOTE: A
 warning indicates a condition on the generator 
which should be addressed, but will not shut down gener-
ator. An alarm shuts down the generator to protect sys-
tem  from  any  damage.  In  event  of  an  alarm,  an  owner 
can clear the alarm and restart generator prior to contact-
ing  an  IASD.  Contact  an  IASD  if  the  intermittent  issue 
occurs again.
Emissions
The United States Environmental Protection Agency (US 
EPA)  (and  California Air  Resources  Board  (CARB),  for 
engines/equipment  certified  to  California  standards) 
requires  this  engine/equipment  to  comply  with  exhaust 
and  evaporative  emissions  standards.  Locate  the  emis-
sions compliance decal on the engine to determine appli-
cable standards. See the included emissions warranty for 
em
issions warranty information. Follow the maintenance 
specifications in this manual to  ensure  the  engine  com-
plies with applicable emission
s standards for the duration 
of the product’s life. 
This  generator  is  certified  to  operate  on  liquid  propane 
vapor fuel or pipeline natural gas.
The Emission Control System code is EM (Engine Modifi-
cation). The Emission Control System on this generator 
cons
ists of the following:
:
Fuel Requirements
The  engine  has been  fitted  with  a  dual fuel  carburetion 
system. The unit will run on NG or LP gas, but has been 
factory-configured to run on NG. The fuel system will be 
configured  for  the  available  fuel  source  during  installa-
tion.
Recommended  fuels  should  have  a  BTU  content  of  at 
lea
st 1,000 BTUs per ft
3
 (37.26 megajoules per m
3
) for 
natural gas, or at least 2,500 BTUs per ft
3
 (93.15 mega-
joules per m
3
) for LP gas.
NOTE: If 
converting to LP gas from NG, a minimum LP 
tank size of 250 gal (946 L) is recommended. See instal-
lation manual for complete procedures and details. 
Battery Requirements
12  volts,  Group  26R  Wet  Cell  540CCA  minimum  or 
Group  35  AGM  650CCA  minimum  (not  included  with 
unit.) See Battery Maintenance for correct battery main-
tenance procedures.
Battery Charger
The  battery  charger  is  integrated  into  the  control  panel 
module in all models. It operates as a smart charger, ver-
ifying  output  charging  levels  are  safe  and  continuously 
op
timized to promote maximum battery life. A kit is pro-
vided  to  install  a  fuse  in  transfer  switch  for  T1  battery 
cha
rger  connection.  Follow  installation  instructions  pro-
vided with kit.
NOTE: Do
 not use external battery chargers.
Engine Oil Requirements
See Engine Oil Requirements for correct oil viscosity.

DANGER
Explosion and Fire. Fuel and vapors are 
extremely flammable and explosive. Add fuel 
in a well ventilated area. Keep fire and spark 
away. Failure to do so will result in death 
or serious injury.
