    1-5. Operation Do not disconnect the earth conductor cable on the UPS or the building wiring terminals in any time since this would cancel the protective earth of the UPS system and of all connected loads. The UPS system features its own, internal current source (batteries). The UPS output sockets or output terminal blocks may be electrically live even if the UPS system is not connected to the building wiring outlet.

In order to cut off the output, switch off the line input breaker(for dual input unit, also switch off the bypass line breaker). A few seconds later, there is no display shown on the display panel and UPS is complete off.
