1.5Operating Modes (continued)

1.5.8Manual Bypass Mode (Parallel UPS)

Similar to manual bypass mode for a single UPS system (Section 1.5.4), except with parallel (1+1) UPS systems. 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.
