Bypass Mode
In the event of a UPS overload or internal failure, the UPS transfers your
equipment to utility power. Battery mode is not available; however, the
utility power continues to be passively filtered by the UPS. The alarm
sounds and the
μ
indicator illuminates red. The UPS transfers to
Bypass mode when:
S
The UPS has an overtemperature condition.
S
The UPS has an overload condition of 102 to 110% for 2 minutes.
S
The UPS has an overload condition >110% for 12 cycles.
S
The UPS detects a fault in the UPS electronics.
Standby Mode
When the UPS is turned off and remains plugged into a power outlet,
the UPS is in Standby mode. The
μ
indicator flashes and the load level
indicators are off, indicating that power is not available to your
equipment. The battery recharges when necessary.
Configuration Mode
When the UPS is in Configuration mode, the front panel indicators
represent the configuration options. Use the control buttons
(On
button, Off
button, and
button) to modify the UPS
configuration. Figure 24 shows the indicators and Table 9 explains the
corresponding options.

Press the On
button and the

If the indicators start cycling automatically from left to right, repeat Step 1 and be
sure to press both buttons.
2.
Press the On
button to scroll through the options. Each time you
press the button, the UPS beeps. The indicator for the selected
