N.B. In this case the power which can be taken from each of the
two outputs is half the rated nominal power.
- Ensure that the sum of the loads to be supplied does
not exceed the nominal power of the electric generator.
- Magnetothermic protective devices or similar should
be placed between the generator and electrical
equipment, according to the tables shown below.
- To make both parallel and serial connections, use the
special bridges provided in the accessories to the
electric generator on the terminal board fig. 15 ref. 1.
