8-5 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.

8-6 Battery Backup Mode (Parallel UPS)

Similar to on battery backup mode for a single UPS system (Section

8-2), except the total connected equipment load is shared by the parallel (1+1) UPS systems.

8-7 Auto Bypass Mode (Parallel UPS)

Similar to auto bypass mode for a single UPS system (Section 8-3), except with parallel (1+1) UPS systems.
