2.6 Operating Modes
The UPS operation modes include the following: Mains (AC) Mode, Bypass Mode, Battery Mode, Battery
Recharge Mode, Active ECO Mode and Frequency Converter Mode.
Refer to Operation and Display Panel on page27 for details about the operating mode indicators and
control buttons.
2.6.1 Mains Mode
During Mains Mode, the mains provides input power to the GXT4. The filters, PFC circuit and inverter
process this power to provide high-quality sine wave power to connected loads. The UPS maintains the
batteries in a fully-charged state.
2.6.2 Manual Bypass Mode
Manual Bypass Mode occurs when the unit is manually placed in internal bypass by navigating the LCD
menu to select 3 Control > 1 Turn On & Off > Turn UPS Bypass. Bypass operation is indicated by an audible
alarm and illuminated amber bypass indicator. (If other indicators are illuminated, refer to
Troubleshooting on page49). During Bypass Mode, mains power bypasses the inverter and provides
energy to the connected load.
NOTICE
Risk of loss of power to the connected load. Can cause equipment damage.
Turning Off the UPS in Bypass Mode will result in loss of output power to the connected load.
