• The terminal connection of the primary side of
the transformer are labeled H1, H2, H3, and
H4. Terminals H2 and H3 are shorted together
to provide a series connection for 460 V
application. Terminals H1 and H4 are
connected to 460 V power source to supply
power to secondary side.
• Terminals X2 and X3 of the secondary side are
also shorted together to provide 230 V output
between terminals X4 and X1.
