On my freshly installed RPC I am getting 460 Volts 3 phase on H1 and H2, 462 Volts 3 phase on H1 and H3, and 390 Volts 3 phase on H2 and H3. H3 is the generated 3 phase leg.
Is the 390 volts due to run capacitors not being balanced? Would it be safe for me to run my machine with one leg at 390 volts? It's a 30hp VFD waterjet. The machine specs call for 440-500 volts 3 phase.
