smoothly in order to obtain the greatest efficiency. Irregularities can be detected in less than a second and the on-line mode can be reactivated immediately. Switching back to online mode occurs when the input voltage exceeds ±10% (or ±15% selectable), when the input frequency exceeds ±3Hz, or when no input line is available.

Although high efficiency is standard, the default operation is the on-line mode. From the LCD display panel, Bypass can be activated as required or On-line operation can be run permanently if preferred.

2.3Auto-Restart

In the event that a power failure lasts longer than the UPS backup time, the UPS will shut down. Upon power restoration, the UPS will restart automatically in On-Line mode, which includes output power being restored to the load and the start of battery recharge.

2.4Free Run Mode

Free run mode is a mode of operation in which the UPS outputs a pre-set frequency (50 or 60 Hz) regardless of the input frequency. The UPS operates in free run mode when the input frequency is outside of the selected input frequency range. When starting the UPS, the targeted frequency is 50 or 60 Hz ±0.25 Hz.

2.5Diagnostic Tests

When the UPS is started, a diagnostic test is executed automatically that checks the electronics and battery, and reports any problems on the LCD display.

The advanced battery management system monitors the performance of the battery and will indicate if battery replacement is required. The battery management system tests the battery every 30 days of normal mode operation. A battery discharge test is performed and reports any problems on the LCD display.

Except during the first 24 hours after startup while the UPS is in charging mode, diagnostic tests can be performed manually from the front panel when required.
