2. Product Description 2. 3 Operating Principle Bypass Input Output AC/DC AC/DC Input filter Output filter converter inverter AC/DC Charger converter • Figure 2-3 The UPS operating principle Battery 1. Input filter: it filters the input and provides clean AC power to the UPS. 2. AC/DC converter: In Normal mode, it converts the AC input power to regulated DC power, and raises the regulated DC voltage for DC/AC converter. 3. DC/DC converter: Raises the DC Voltage from the battery system to the optimum operating voltage for the inverter when the UPS operates in Battery mode. 4. DC/AC inverter: In Normal mode, it utilizes the DC output of the AC/DC converter and inverts it into precise, regulated sine wave AC power. In Battery mode, it receives energy from the battery through the DC/DC converter.
3. Installation 3. 1 Unpacking Inspection 1. Open the packing box of UPS and take it out, visually examine the unit for transit damage. 2. Check against the accessory lists that the accessories of the UPS are present. (Refer to Table 9-1). 3. Make sure the model is what you wanted from the nameplate on the rear panel. 4. If the UPS arrives damaged, or there is any missing accessory or other question above, please contact the distributor immediately. 3. 2 Installation Notes 1. When locating the UPS, make sure there is no hazardous objects such as water, inflammable gas, corrosive agents and so on around the UPS, and that the installation environment meets the specifications.

3. Product Description 3.3.2 Operation Procedure of External Battery for Long Backup Time UPS The battery connection procedure is very important for long backup model. Any incompliance may result in the risk of electric shock. Therefore, the following steps must be strictly complied with. 1. First connect in series the batteries of the pack BATTERY BANK to ensure proper battery voltage that 1K/1KL for 36VDC, 2K/2KL for 72VDC (or 96VDC), 3K/3KL for 96VDC. 2. Take out the battery cable delivered with the UPS, one end of the external battery cable is a plug for connecting the UPS, the other end has 3 open wires for connecting the battery pack.
4. Operation (LCD model) 4.2 Operation Mode UPS Operation Mode contains normal mode, battery mode and bypass mode. Under the three modes, the page showing output voltage and output frequency is the main display page. If users need more information about UPS, Pressing the function button can initiate display screen switch. If the current page is not the main page, UPS will automatically switch back the main page after 30 seconds. In order to extend the LCD usage life, the backlight will turn off after 1 minute without any switch operation. At this point, Users just need to touch any button briefly to turn on the backlight. 4.2.1 Normal mode In the normal mode, the display on the front panel is shown in the following diagram. The utility power indicator and the Inverter indicator are turned on. The load/battery capacity indicator will be turned on in accordance with the load capacity connected. 1.

4. Operation (LCD model) 220 50.0 OUTPUT Figure 4-3 Battery Mode 2) When the battery capacity decreases, the number of battery capacity indicators turned on will decrease. If the battery voltage drops to the pre-alarm level, the alarm will beep every second to remind the user of insufficient battery capacity. 3) The other four display pages are load percent page, actual load page, battery information page and the maximum temperature page. 4.2.3 Bypass Mode When operating in bypass mode set up through UPSilon software, the display on the front panel is shown as the figure 5-4, the utility power indicator and the bypass indicator are turned on. Load information area shows load value, and the battery level area indicates dynamically when the battery is not fully charged (the battery level icons lit one after another circularly). When the battery is fully charged, all the level icons are turned on. 1) When operating in bypass mode, the UPS beeps every 2 minutes. If the “Function” key 215 50.0 pressedfor more than 2 seconds, the...
4. Operation (LCD model) 4.2.4 LCD indication of UPS alarm status and faults In the event of an UPS fault, UPS enters fault operation mode, at this point, the fault icon turns on consist- ently, the buzzer beeps continuously and the data information area shows current fault code (refer to table 7-2), the display on the front panel is shown as the figure 5-5, users can switch to output page by pressing function button. F0 1 Figure 5-5 Fault display When a warning occurred, the fault icon blinks every second, and users can switch to the alarm display page shown as the figure 5-6 to check the warning code.
4. Operation (LCD model) 1. Turning on the UPS The operation of turning on the UPS contains: turning on with utility power and turning on without utility power. 1) Turning on with utility power: Connect the mains input to the UPS, press the ON button more than one second, UPS starts to turn on. At this point, the LCD begins to conduct self-diagnosis (all the LCD indicators are turn on about 4 seconds). A few seconds later, the UPS will begin to operate in Normal mode; meanwhile, the utility power indicator, inverter indicators will turn on.
4. Operation (LCD model) 3) If you need to set the voltage, check the voltage setting is enabled ("VAC" is flashing), If not, press the 'F' more than one second, then release, the output setting is enabled, at this point you can start to set output voltage.
