The differences between models of the generator sets covered in this manual areas follows:
Model MEP-806A is equipped with a 50/60 Hz generator, 50/60 Hz frequency meter, and frequency selector
switch.
Model MEP-816A is equipped with a 400 Hz generator and 400 Hz frequency meter.
Performance characteristics for the two models are shown in TABLE 1-2.
