7.1.3 Battery Mode
The UPS transfers to Battery mode automatically if a utility power outage occurs, or if
the utility power does not conform to specified parameters. In Battery mode, the
battery provides emergency DC power that the inverter converts to AC power. When
the UPS switches to Battery mode, the alarm indications depend on the cause and
condition of the battery charge. The length of time the system can operate in Battery
mode depends on load configuration and battery charge.
Figure 7‐4 shows the path of electrical power through the UPS system when the UPS
is operating in Battery mode.

Figure 7‐4. Path of Current Through the UPS in Battery Mode
When the discharging battery voltage reaches the lower limit of UPS operation capability,
the critical load transfers to Bypass mode if it is available. If Bypass input is not available, a
Shutdown Imminent warning occurs. The warning time before critical load loss occurs is
approximately two minutes, depending on load configuration and battery charge.
If incoming power returns to within specified parameters, the UPS automatically returns
to Normal mode and alarm indications clear. However, the process of returning to Normal
mode is not instantaneous. The rectifier gradually draws increasing power from the
incoming utility until Normal mode is achieved.
