In order to design a suitable system for distributing the power output from the UPS between the consumable loads, as well as the correct management of the UPS outputs and the input and outputs of isolated transformers, as well as the use of the manual by-pass key for repairs or servicing of the Cadillac Faratel series machines that do not have this manual switch based on their design principles, the Faratel manual by-pass board has been designed and produced.
