Initial start-up
Connection with Utility
Do not disconnect the mains cable on the UPS system or the building wiring outlet (shockproof socket outlet)
during operations since this would cancel the protective earthing 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 terminals
block may be electrically live even if the UPS system is not connected to the building wiring outlet.
PRECAUTION
Make sure grounding is properly done.
