Using a 230V/24 Vac transformer
Some transformers (as in typical plant room
installions) are earthed on one side of the
secondary; therefore care must be taken to
ensure that the earthed side of the transformer
secondary is connected to the middle terminal
of the power connector. If the polarity of the
connection is incorrect the unit will not power
up. If this happens you should swap the left
most and center connections over and the
unit should power up unless there is another
fault.
CAUTION: Do not apply mains power to
this connector.
