Yes, this UPS is doing its job, but be warned, during the installation, probably caused by the vagaries of the transport, the battery is detached from its husks, and result in smoke cleared, persuading me fast cutting, and replace the battery on its terminals.

To conclude the documentation is very spartan and does not attract all the attention on this kind of potential risk.
