Do not block the airflow from radiator vent or muffler exhaust. It may result in reduced engine
performance, overheating, or damage to the electrical parts.
Operating in dusty area or salty air (by the ocean), or any other particulate environment may result in
clogged radiator, which may cause overheating, other malfunctions and insulation deterioration.
Use extreme care, frequent checks and maintenance.
7 Connection
7.1 Selecting Cable
Select the cable with proper gauge, based on its allowable amperage and the distance between
the generator and the machinery to be connected.
!
Caution
:Electrical damages
If the load exceeds the allowable amperage, the overheating may damage the cable.
If the cable is either too long or too small a gauge, there will be greater voltage drop to loads, which may
result in reduced performance in the connected loads, malfunction, or damages.
<Caution>
It is recommended to select the proper gauge and length of cable, with consideration of the
maximum 5% marginal drop only for the rated voltage, between the terminals of loads and
generator via the cables.
