Good product, easy to install when you fluent in English .... but the supplied cables and sockets on the machine being the US standards, it is essential to couple this purchase to that of a Special Power Strip Belkin power strip for UPS 3 taken Europa Black. Then simply plug the power strip on one of the three rear jacks and connect the equipment to be protected on the strip.
