Jor,

The switches are probably to tell you which connections are being monitored
by the meters. As the generator is three phase the loads can be connected
in several ways. It allows you to balance the loads between phases. It
probably also allows you to connect your loads to several optional voltages
and to use either "Y" or "D" configuration. For instance you'll probably be
able to use 115 vac single phase up to 416 vac three phase.

This could well be a former military generator with a convenient "tap
channge over board" and a 50/60 hertz capability. If so, it would be very
worth your while to get the military technical publication operators manual.

Do you have the manufacturer and model information?

I 'inherited' a 3phase 15KW generator without documentation or even a brand
name on it. It works well enough but I don't understand some of the
switches on its front panel. Perhaps somebody more into generators then I
am can explain them?

Except for the start/stop switch (I do understand that one) there are two
other switches, marked with the following positions:

switch 1 :
L1L2
L2L3
L1L2 -- set on this position
OFF
L1-N
L2-N
L3-N

switch 2:
OFF
L1 -- set on this position
L2

What function do these switches have? Is it safe to 'try out' the other
settings?

TIA

Jor
