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.
Load Cable Selection Tables
(Ex.) If used voltage is 440V and voltage drops by 22 V.

7-2.Connecting Load Cables
WARNING : ELECTRIC SHOCK
Before connecting or disconnecting the load cables to/from the output
terminal, always turn the output circuit breakers to the
“OFF” position, stop
the engine, and remove the starter key.
Close the output terminal cover before operating.
Do not touch the generator if the Alternator or casing becomes wet during operation.
CAUTION : FIRE
Do not connect the generator output to indoor wiring.
