7.4O perating Modes

7.4.1“ON LINE” Mode (INVERTER MODE)

The ON-LINE Mode is the UPS Operating Mode in which the load is supplied through the RECTIFIER and INVERTER. LED indicators are illuminated when shown shaded:

Using the control panel (see Figure 7–2) the UPS can easily be transferred to the ON- LINE mode. The ON-LINE mode provides the highest degree of protection, especially in the event of a supply disturbance or failure. This operating mode is always recommended if the critical loads (computer systems) will not tolerate any interruption of the supply, even for a very short time. In the unlikely event of an inverter fault or overload condition, the UPS will transfer the load automatically and without interruption to the static bypass-utility supply.

7.4.2 “OFF LINE” Mode (BYPASS or ECONOMY MODE)

In the OFF-LINE mode, the load is supplied from the utility supply through the bypass. Using the control panel (see Figure 7–2), the UPS may be easily transferred to “Bypass Mode”.
