1 Basic Operation (continued) 1.5 Operating Modes This section provides a basic description of the UPS system’s operating modes. For more information about switching between operating modes, refer to Section 1.6 – Start-Up, Shutdown and Bypass. 1.5.1 Online (Normal) Mode (Single UPS) In online (normal) mode, the UPS system’s rectifier converts incoming AC utility power to DC power that charges the batteries and supplies the inverter. The inverter transforms the DC power to precision-regulat

1 Basic Operation (continued) 1.5 Operating Modes (continued) 1.5.5 Online Mode (Parallel UPS) Parallel redundancy (1+1) provides UPS system redundancy or increased total capacity. Under parallel redundancy, the total load is shared by two UPS systems. If one of the UPS systems malfunctions, the total connected equipment load is supported by the remaining UPS system. If the total load exceeds the capacity of the remaining UPS system, it will switch to auto bypass mode. 1.5.6 Battery Backu

Note: Both UPS systems must be switched into manual bypass mode. 1.5.9 Hot Standby Mode (Parallel UPS) For added fault-tolerance, the redundant UPS system acts as the bypass (reserve) power source for the main UPS system. 17 PRELIMINARY

1 Basic Operation (continued) 1.6 Start-Up, Shutdown and Bypass Warning: The UPS system’s output voltage is set at 220/380V by default. If you require output voltage of 230/400V or 240/415V, you must change the UPS system’s output voltage by accessing the output setup menu described in Section 10-9 of the owner’s manual. You must place the UPS system in bypass mode before changing the output voltage. Do not connect your equipment to the UPS system’s output until you have set the proper para
