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.
