Is anybody else confused by the logic of the EC information?
My understanding of the system, suggests that when you plug in the GPU and switch the Battery Master switch on, the battery and generators are isolated from the Primary Bus Bars to prevent any flow of current between Battery and GPU. If this is the case, how does the Battery act as a 'Buffer'.
Eurocopter also recommend that the battery is disconnected when operating with an EPU for an extended period of time.
