Free Run Mode
The UPS operates in free run mode when input frequency is outside of the selected input frequency range.
Free run mode is when output frequency does not match input frequency. When starting the UPS, the
frequency regulation detected is 50 or 60 Hz ±0.25Hz. Please refer to chapter 7.2 if you want bypass
available while running in free run mode.
Diagnostic tests
When you start the UPS, a diagnostic test is automatically executed that checks electronics, battery, and
reports any problems on the LCD display.
An advanced battery management system always monitors the conditions of the batteries sends any
forewarnings if replacement is needed. Otherwise every 30 days of normal mode operation, a battery
discharge test is performed and any problems reported on the LCD display.
Except during the first 24 hours after startup while the UPS is in charging mode (please see chapter 7.2),
diagnostic tests can be performed manually from the front panel at any time.
