3. Operation Mode and UPS Operation

3.1 Operation Mode

This modular UPS is a two-phase, three wire on-line, double-conversion and reverse-transfer UPS that permits operation in the following modes:

 Standby Mode  Line Mode  Battery Mode  Bypass Mode  ECO Mode  Shutdown Mode

3.1.1 Standby Mode

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.

3.2.2 Line Mode

In Line Mode, the rectifier derives power from the utility power, 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.

Line Mode Diagram

Battery Mode Diagram

Keatec RTM Series Modular Onlne UPS 208-120Vac 2PH-2PH User Guide English 20180109

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.

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.), UPS will perform 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.

Bypass Mode Diagram

ECO Mode Diagram

Keatec RTM Series Modular Onlne UPS 208-120Vac 2PH-2PH User Guide English 20180109

3.2.5 ECO Mode

The ECO Mode is enabled through the LCD setting menu. 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.

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.

Shutdown Mode Diagram

 Do not start the UPS until the installation is completed.  Make sure the wiring is correct and the power cables are fixed firmly.  Make sure input and output breakers are switch OFF.

This chapter introduces how to replace the UPS module.

Warning:

1. Only the customer service engineers can do this service.

2. Remove the UPS modules from top to bottom, so as to prevent cabinet from toppling due to high center of gravity.

7.1

UPS module replacement

Warning:

 Confirm UPS is in Line mode or Bypass mode.  Confirm at least one UPS module remains in the UPS cabinet after one UPS module is

removed.

 If all UPS modules have to be removed, the replacement MUST be under Maintenance Bypass

Operation Mode.

1. The ALARM LED (RED) is lit on the UPS module to indicate the UPS module output is off and

disconnected from UPS system.

2. Use a screwdriver to remove the four screws from fixing holes.

3. Two people pull out together and remove the UPS module from its slot together.

4. After servicing the module, push the module into the cabinet and tighten the screws on both

sides. If there are more than one UPS module to re-install, please wait 30-second before installing another module.

5. The re-installed UPS module will be turned on automatically when UPS is in line mode.
