When opening one of the terminals add (except the universal one which can't be tested because there is currently no way of installing terminals on it) the UI shows up for a few moments until its energy is empty. This only happens in survival mode because in creative mode the energy consumption is deactivated. It seems like it consumes the 1600000AE in just one tick. This can't be intended since it is unusable in this state as nothing can charge it fast enough to work longer (tried FluxNetworks wireless charging).
