1.6.1. Maintenance Bypass
On 5-kVA to 10-kVA models, the UPS includes manual maintenance bypass in a removable section of the rear of
the UPS. Maintenance bypass keeps connected equipment powered with utility power and allows replacement of
the UPS in the event of a UPS malfunction. Figure 1-14 on the next page, shows a diagram of bypass mode.
NOTE: The bypass power path does not protect the connected equipment from disturbances in the utility power
supply.
1.7. UPS States and Operating Modes
NOTE: See LED Indicators on page 44, for description of the run-indicator and alarm-indicator LEDs mentioned
in this section.
1.7.1. Normal Mode
When utility power is normal, Normal mode employs the rectier and inverter to provide voltage- and frequency-
stabilized power to the load. The charger charges the battery in normal mode. On the front- panel display, the
run-indicator (green) is ON, the alarm indicator is OFF, and the buzzer is silent. Figure 1-13 on the facing page,
shows a diagram of normal mode.
