this generator canresult in damageor malfunction.
6-2. Installation Procedures
WARNING : EXHAUST GAS POISONING
Do not operate the generator in poorly ventilated areas such as indoors or
tunnels, as the exhaust gas of the engine contains substances that are
harmful to human health.
Do not direct exhaust fumes at bystanders or buildings.
CAUTION : FIRE
Do not bring flammable items (such as fuel, gas and paint) or items that are
highly combustible near the generator as the muffler, exhaust gas and other
parts become extremely hot.
Operate this generator 3 ft. (1 m) or more from walls or other hindrances,
and on a level surface.
Remove the wood ties if using anchors to secure the generator
Do not connect the generator output to indoor wiring.
If installing this generator, set up barriers or fencing completely around the boundary
line of the construction area and take measures to prevent persons not involved in the
construction from entering the area.
Position this generator on a hard, flat and level surface that serves as the foundation.
Position this generator 3 ft. (1 m) or more from walls or other hindrances so that the
operation panel door and left/right check doors are accessible for internal
inspection/maintenance.
< NOTE >
Thisgenerator is manufactured presupposing that it will be installed on a flat, hard and level
surface that serves as thefoundation.Accordingly, care must betaken as using under anyother
installation conditions can result in a fault or malfunction.
Do not place any objects wherethey will interfere with the radiator or muffler exhaust ports.
Objects interfering withthese ports will result in reduced engineoutput, overheating, and electrical
componentfault/malfunction.
Operating the equipment in dustyorexcessively salty location can result in a cloggedradiator or
overheating resulting in malfunction/fault or reduced insulation of electrical components. Be sure
to thoroughly inspect and perform maintenance if using in such locations.

7. Load Connections
7-1. Load Cable Selection
CAUTION : PROPERTY DAMAGE
Cable burnout can occur due to generated heat if the load current exceeds
the allowable current of the cable.
The voltage drop between cables is large if the cable is excessively long or
thin, resulting in decreased input voltage to equipment using the generator,
thereby causing decreased performance, faulty operation and malfunction.
Select cable for use that has sufficient thickness and an allowable current possible for use,
giving consideration to the distance from the generator to the equipment using the generator.
< NOTE >
Select cable with a thickness that ensures that the voltage drop across the cable will be
within 5% of the rated voltage.
