4 Operations

4.1 Modes of Operation

4.1.1 Off Mode

The UPS input is plugged into a stable, nominal source, but the outlets are turned off. The internal
batteries are charging.

4.1.2 On/Normal Mode

The UPS input is plugged into a stable, nominal source, and the outlets are turned on. The internal
batteries are charging.

4.1.3 On/Automatic Voltage Regulation (AVR)/Boost1 Mode

The UPS input is plugged in, but the voltage source is somewhat low (brown-out). The UPS automatically
corrects the low voltage and allows the outlets to be on with the normal, expected voltage. The internal
batteries are charging.

4.1.4 On/Automatic Voltage Regulation (AVR)/Boost2 Mode

The UPS input is plugged in, but the voltage source is abnormally low (brown-out). The UPS automatically
corrects the low voltage and allows the outlets to be on with the normal, expected voltage. The internal
batteries are charging.

4.1.5 On/Automatic Voltage Regulation (AVR)/Buck Mode

The UPS input is plugged in, but the voltage source is abnormally high. The UPS automatically corrects
the high voltage and allows the outlets to be on with the normal, expected voltage. The internal batteries
are charging.

4.1.6 On/Battery Mode

The UPS input is not plugged in, or the voltage source has become extremely low or high and unusable.
The UPS automatically switches to the internal battery to provide normal, usable voltage to the outlets.

4.1.7 Fault Mode

An error or fault condition has occurred. The outlets are shut off.

4.1.8 Battery Self-test Mode

The UPS enters a cycle of approximately 10 seconds during which it tests the internal battery. The outlets
are still temporarily powered by the internal battery. Self-test mode occurs at the following instances:
• At start-up turning the UPS on.
• Automatically every 8 weeks as a self-check.
• When selecting the Replace battery option under Control > Start/Stop battery manual test
