Simply plug the load power cord to the output sockets to complete connection. Use one cord for every 5A load. Model No.
(3) EPO Connection: User can select the polarity of EPO, EPO is Normally open as default setting. ● Normally open Normally the EPO connector is open on the rear panel. Once the connector is closed with a wire, the UPS would stop the output until the EPO status is disabled. Disable the EPO status Enable the EPO status ● Normally close Normally the EPO connector is closed with a wire on the rear panel.
5.4 Turn on the UPS: (1) With utility power connecting: Press “I” button continuously for more than 1 second to turn on the UPS, the UPS will get into the inverter mode, the LCD screen will indicate the state of the UPS.
5.7 Audible alarm mute function: If the alarm is too annoying in battery mode, you may press “I” button continuously for more than 1 second to clear it. Moreover, the alarm will be enabled when the battery is low to remind you to shutdown the load soon. If the alarm is too annoying in bypass mode, you may press “ “button continuously for more than 1 second to clear it. The action doesn’t affect the warning and fault alarm. 5.
(6) The red wire is connected to the "+" terminal of the battery. The black wire is connected to the "-" terminal of the battery. (Note: the green/yellow wire is grounded for protection purpose.) (7) Make sure the wires are fasten, install the terminal block cover on the rear panel of the UPS. (8) Connect the UPS to the load. Then, turn on the mains switch or connect the power cord of the UPS to utility power supply, the battery would start to be charged.
6. Operating Mode for All Models The different codes could be displayed on the LCD screen corresponding to their own operating modes, and they are illustrated as the following table. At any time, only one normal operating mode or fault mode is presented. But the warning, even several warnings could appear in a certain normal operating mode at one time. And the normal operating mode code and the warning code would be shown circularly.
■ The Line mode If output overloaded, the load percent is shown and alarm will keep twice every second. You should get rid of some unnecessary loads one by one to decrease the loads connected to the UPS less than 90% of its nominal power capacity. Note: Please follow the following steps to connect the generator： ● ● Activate the generator and wait until the operation is stable before supplying power of the generator to the UPS (be sure that the UPS is in idle mode).
(1) When the UPS is running in battery mode, the buzzer beeps once every 4 seconds. If the “ON” button on the front panel is pressed for more than 1 second again, the buzzer will stop beeping (in silence mode). Press the “ON” button once again for more than 1 second to resume the alarm function.
■ The Bypass mode The UPS does not have the backup function when it is in bypass mode. The power used by the load is supplied from the utility power via internal filter. 6.4 NO output mode The LCD display in No output mode is shown in the following diagram. The information about the utility power, the battery, the UPS output and the load could be displayed. The “0” code indicates the UPS is working in the No output mode.
6.5 EPO (Emergency Power Off) It is also called RPO (Remote Power Off). On LCD display, the mode code is “0”, the word of “EPO” are presented in the position of output voltage. It is a special status in which the UPS would shut the output off and alarm. The UPS could not be turned off by pressing “OFF” button on the panel, only after releasing EPO status by turning off the EPO switch. 6.6 ECO mode (Economy mode) It is also called high efficiency mode. In ECO mode, on LCD display, the mode code is “5”.
2) The load should be derating to 60% in converter mode. 6.8 Abnormal mode In abnormal mode such as Bus fault etc., the corresponding fault code would be shown to indicate the operating mode of the UPS. And some warning words could also be shown, for example “short!” would be shown when the load or the UPS output is short and the UPS is in inverter fault mode.
7. Setting by LCD Module The output voltage and frequency, and bypass state, and ECO mode, and Converter mode could be set directly through LCD module. The output voltage could be set to 208V, 220V, 230V and 240V. The output frequency could be set to 50Hz and 60Hz. The operating mode of UPS could be set between the Line mode, ECO mode and Converter mode. The bypass state could be set to enable and disable. But all the settings could only be done when the UPS is in bypass or no output mode.
■ Here is a example for changing the output voltage from 220Vac to 230Vac through the LCD panel. Step 1: One flickering black dot would appear before “208Vac” after pressing the “Select” button. Step 2: The flickering dot would move to “230Vac” after pressing the “Select” button two times again.
Step 3: The dot before “230Vac” would turn to flickerless after pressing the “Enter” button. Step 4: The output voltage would be 230Vac after the UPS is turned on.
