As it's AC you don't have to pay attention to the polarity. But pay
attention to connect the cables to the right terminals of the power supply
board as shown in the manual (both terminals are labelled "15V AC"). Do not
use the terminal with the shield/earth symbol for the transformer. Some
customers fried their transformer by using this terminal to connect the
transformer. The shield/earth terminal is used only in case of a metal
housing to ground the housing.
