OTE
:
No separation transformers for three wires voltage connection (without N) are needed.
Switchboard lighting strikes protection according standard regulation is expected!!!
Single phase applications
There is not a separate archive file for single-phase applications. Use standard ail archives.
Recommended wirings
Generator (and mains) single-phase voltage has to be connected to all three-voltage terminals L1, L2
and L3.
