Upon connecting to utility input power, the UPS is in Standby mode before UPS is turned on (if BYPASS enable setting is Disabled), and charger function will be active when the battery is present. The load is not powered under this mode.

Figure 3-3 : Standby Mode Diagram

3.2.2 Line Mode

In Line Mode, the rectifier derives power from the utility power and supplies DC power to the inverter and the charger charges the battery. The inverter filters the DC power and converts it into pure and stable AC power to the load.

Figure 3-4 : Line Mode Diagram

3.2.3 Battery Mode

The UPS automatically transfers to Battery mode if the utility power fails. There is no interruption in power to the critical load upon failure. In battery mode, the rectifier derives power from the battery and supplies DC power to the inverter. The inverter filters the DC power and converts it into pure and stable AC power to the load.

Figure 3-5 : Battery Mode Diagram

3.2.4 Bypass Mode

Upon connecting to utility input power, the UPS is in Bypass mode before UPS is turned on (if BYPASS enable setting is Enabled), and charger function will be active when battery is present.

After UPS has been turned on, if the UPS encounters abnormal situations (over-temperature, overload …, etc.), the static transfer switch will perform as a transference of the load from the inverter to the bypass source with no interruption. If the transference is caused by a recoverable reason, the UPS will turn back to line mode when abnormal situation is solved.

Figure 3-6 : Bypass Mode Diagram

3.2.5 ECO Mode

The ECO Mode is enabled through the setting menu of LCD panel. In ECO mode, the load is powered by bypass when the bypass voltage and frequency are within the acceptable ranges. If the bypass is out of range, the UPS will transfer the power source of load from bypass to inverter. In order to shorten the transfer time, the rectifier and inverter are working when the UPS is in ECO mode.

Figure 3-7 : ECO Mode Diagram

3.2.6 Shutdown Mode

When the UPS is in the off state and the utility power source is absent, the UPS will enter into shutdown mode. Or when the UPS has discharged the battery to the cut-off level, the UPS will enter into shutdown mode as well. When the UPS enters this mode, it is going to shut off the control power of UPS. The rectifier, charger and inverter are all in off state.

Figure 3-8 : Shutdown Mode Diagram

3.2.7 Maintenance bypass Mode

A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS becomes unavailable e.g. during a maintenance procedure. Before entering the maintenance bypass mode, make sure the bypass power source is normal.

9. UPS Installation for Parallel Rack System

The chapter introduces how to install and set up the single rack system to parallel rack system.

Warning:

 The input harmonic current distortion will be higher than 3% and less than 4.5% in parallel

rack system.

 You need to order the parallel cable for this kind of application. The parallel is required for the

installation and operation.

 The firmware version of power module must be 10.58 or higher and firmware version of LCD

must be 11.50 or higher.

 If you want to install the UPS to parallel rack system by yourself, installation must be under

the supervision of authorized engineers or service personnel.

 The parallel rack feature only support eight power modules with 210K maximum power in one

rack. One of the eight power module is configured as redundancy power module. The parallel rack system’s maximum power can be 210K + 210K.

9.1 Input and Output Wiring

1. When install the parallel rack system, the input wires (R, S, T, N) length of the Rack must be equal to another Rack input wires. Likewise, the output wires (R, S, T, N) length of the Rack must be equal to another Rack output wires. The same length of input and output wires of two Racks are required, or it will cause the unbalance current of output load.

2. Refer to Chapter “3. Installation” about the input and output wiring and battery wiring methods in User Manual.
