Connecting power
The controllers require a 24 volt, AC power source. Use the following guidelines when
choosing and wiring transformers to the controller.
l Use a Class–2 transformer of the appropriate size to supply power to the controller.
l KMC Controls recommends powering only one controller from each transformer.
l Do not run 24 volt, AC power from within an enclosure to external controllers.
Connect the 24 volt AC power supply to the power terminal block on the lower right side of
the controller. Connect the ground side of the transformer to the ground terminal and the
AC phase to the phase terminal. Power is applied to the controller when the transformer is
connected to power.
