The power module is equipped with three 12VDC outputs, each delivering 1A. Connect
the 12V voltage outputs of the power module to the 12V power inputs of the preceding
modules (mind the polarity).
Note that the total consumption of the connected modules on one DC output may not
exceed 1A.
Make sure to use an appropriate wire gauge (1mm² or more) with very long connections.
Connect a 12V transformer delivering min. 3A to the power module input. Refer to one
of the following connection diagram depending on the transformer:
