The installation instructions are here

I believe this was one of the Kubes with an ac supply and the rectification built into the Kube, so any transformer with the correct ac output will be fine, as it will not need a huge amount of current. If I'm wrong on the ac, one of the experts here will correct me.

Early KUBES had a built in mains transformer and a captive mains lead. I assume yours is later and has a DIN socket on the back. If so, you need to supply it with a.c. power from a transformer, 12V I think. Does it not say the voltage on the back? There is a rectifier, smoothing and voltage regulators inside, so the transformer type is not critical.
