High voltage exists inside the UPS. Touching such points is very dangerous and hazardous. Accidental
electric arcs can be very hazardous while working inside the UPS (Only trained personal).
Some electrical components are heavy. If replacement is required please use suitable and helpful apparatus.
Otherwise injuries may occur.
Energy storage devices such as batteries and capacitors are used in the UPS. Before maintenance turn off
the device and wait at least 3 minutes to completely discharge the capacitors. Make sure batteries are
