3.1 System Description
The Liebert MicroPOD has two modes of operation: UPS (UPS available) and UTILITY (maintenance
bypass).
•In UPS mode, the power is routed through the UPS system delivering conditioned power to the
load, as shown in Figure 2.1 below.
Figure 2.1 UPS mode of operation
•In Utility mode, power is routed around (bypassing) the UPS system (see Figure 2.2 below).
Utility power is supplied directly to the load through the Liebert MicroPOD.
NOTE: Battery backup and conditioned power are NOT available during the Utility mode of operation.
Figure 2.2 Utility/maintenance bypass mode
•The UPS may be turned off and removed without affecting the load. See Figure 2.3 on the next
