Some transformers are
earthed (grounded) on
one side of the secondary.
If so ensure the earthed
(grounded) side is connected
to the central terminal of
the power connector. If the
polarity of the connection
is incorrect the unit will not
power up. If this happens
swap the left and central
connectors.
