Converter mode
The UPS supplies the load from utility power while acting as a frequency converter,
locking the UPS into a stable output frequency and transferring to Battery mode as
necessary. Bypass mode is not available. Use Converter mode to lock the UPS
output frequency at 50 Hz or 60 Hz to suit power-sensitive equipment, or to provide
50 Hz output when the available standard utility input is 60 Hz (or the reverse).
Battery mode
The UPS supplies the load power from battery. The status text flashes, and the
UPS beeps every 5 seconds. When the utility power returns, the UPS transfers to
Normal mode operation while the battery recharges.
Bypass mode
The UPS supplies the load power through an automatic internal bypass. Battery
mode is not available. The UPS transfers to Bypass mode when you activate
Bypass mode through the front panel (manual bypass) or when the UPS detects a
condition that requires bypass (automatic bypass).
Standby mode
When the UPS is turned off and remains connected to the power source, the UPS
is in Standby mode. The UPS is not supporting the load but is ready to assume the
load on command.
Turning on the UPS
After the UPS is connected to the power source, it enters Standby mode.
To turn on the UPS, press the on/off button for approximately 1 second. The display
changes from the start screen to the UPS Status Summary screen and shows the
Standby icon flashing while the UPS starts.
Starting the UPS on battery
Note: Before you use this feature, the UPS must have been powered by utility
power at least one time.
To turn on the UPS without using utility power, press and hold the on/off button for
3 seconds. The UPS supplies power to the connected devices, and it switches into
Battery mode.
Turning off the UPS
To turn off the UPS, complete the following steps:
1. Prepare the connected devices for shutdown.
2. Press and hold the on/off button until the long beep ceases (approximately 3
seconds). The UPS switches to Standby mode (if utility power is available) and
removes power from the connected devices.
Note: You must turn off the UPS at the power source; otherwise, it remains in
Standby mode. After the power source is removed, the UPS fully shuts down in
10 seconds.
