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 leveled surface.
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 >
This generator is manufactured presupposing that it will be installed on a flat, hard and
leveled surface. Accordingly, care must be taken as using under any other installation
conditions can result in a fault or malfunction.
Do not place any objects where they will interfere with the radiator or muffler exhaust ports.
Objects interfering with these ports will result in reduced engine output, overheating, and
electrical component fault/malfunction.
Operating the equipment in dusty or excessively salty location can result in a clogged radiator
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.
7-1. Load Cable Selection
Select cable for use that has sufficient thickness and an allowable current for use, and 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.
Load Cable Selection Tables
(Ex.) If used voltage is 240 V and voltage drops by 12 V.

CAUTION : PROPERTY DAMAGE
Cable burnout could 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.
