(3) In changing the output voltage over to 400/440, take care not to lose superfluous change
over plates by, for example, setting them together with the actually used ones,
® Mount the protecting cover of the voltage selecting panel again.
[Note]
Incorrect reconnection of the change— over plates may cause a burning accident
the distance between the machine and the load.
If the load current exceeds the allowable current of cables, the cable may be damaged by
overheat. Also, if the cables are too small in size for the length, the input voltage of the load
drops which lowers the working efficiency or causes failure in operation.
Select the length and size of cable so that the voltage drop "e" obtained by the following
equation is within 5% of the rated voltage.
* Equation to obtain 3 - phase, 3 - wire system voltage drop "e" from the length and size of
cable and operating current is as follows.
in the generator. For reconnection, be sure to tighten the plates to prevent the
burning accident.
Be sure to mount the protection cover before starting engine again.

Selection of cables:
Use cables having sufficient size in consideration of the allowable current of the cables and
