1. Important Safety Warning Please comply with all warnings and operating instructions in this manual strictly. Save this manual properly and read carefully the following instructions before installing the unit. Do not operate this unit before reading through all safety information and operating instructions carefully 1-1. Transportation Please transport the UPS system only in the original package to protect against shock and impact. 1-2.
1-5. Maintenance, service and faults The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified maintenance personnel. Caution - risk of electric shock. Even after the unit is disconnected from the mains (building wiring outlet), components inside the UPS system are still connected to the battery and electrically live and dangerous.
For UPS with internally mounted battery a) Instructions shall carry sufficient information to enable the replacement of the battery with a suitable manufacturer and catalogue number. b) Safety instructions to allow access by Service Personnel shall be stated in the installation/service handbook. c) If batteries are to be installed by Service Personnel, instructions for interconnections, including terminal torque, shall be provided. Do not attempt to dispose of batteries by burning them.
2. Installation And Setup NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. Please keep the original package in a safe place for future use. 2-1. Rear panel view IEC Type 1.1K/1.5K NEMA Type 1.1K/1.5K 1. 2. 3. 4. 5. 6. 7. 8. 2K/3K 2K Programmable outlets: connect to non-critical loads. Output receptacles: connect to mission-critical loads.
2-2. Operating principle The operating principle of the UPS is shown as below. Output EMI/RFI Filters AVR TX Inverter DC-to-DC Converter Battery Charger Battery The UPS is composed of mains input, EMI/RFI filters, inverter, battery charger, DC-to-DC converter, battery, AVR TX and UPS output 2-3. Setup the UPS Before installing the UPS, please read below to select proper location to install UPS. 1. UPS should be placed on the flat and clean surface.
Step 1: UPS input connection Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords. Step 2: UPS output connection There two kinds of outputs: programmable outlets and general outlets. Please connect noncritical devices to the programmable outlets and critical devices to the general outlets. During power failure, you may extend the backup time to critical devices by setting shorter backup time for non-critical devices.
3. Operations 3-1. Button operation Button Function ON/MUTE Button OFF/ENTER Button SELECT Button ON/Mute + Select Button Turn on the UPS: Press and hold ON/Mute button for at least 2 seconds to turn on the UPS. Mute the alarm: After the UPS is turned on in battery mode, press and hold this button for at least 3 seconds to disable or enable the alarm system. But it’s not applied to the situations when warnings or errors occur.
Configuration and fault information Indicates the configuration items, and the configuration items are listed in details in section 3-5. Indicates the warning and fault codes, and the codes are listed in details in section 3-7 and 3-8. Mute operation Indicates that the UPS alarm is disabled.

UPS Setting Parameter 1 Parameter 2 01: Output voltage setting Interface There are two parameters to set up the UPS.
115: presents output voltage is 115Vac 120: presents output voltage is 120Vac (Default) 127: presents output voltage is 127Vac 02: Programmable outlets enable/disable Interface Setting Parameter 2: Enable or disable programmable outlets. ENA: Programmable outlets enable DIS: Programmable outlets disable (Default) 03: Programmable outlets setting Interface Setting Parameter 2: Set up backup time limits for programmable outlets.
08: EPO logic setting Interface Setting Parameter 2: Set up the EPO function control logic. AO: Active Open (Default). When AO is selected as EPO logic, it will activate EPO function with Pin 1 and Pin 2 in open status. AC: Active Close. When AC is selected as EPO logic, it will activate EPO function with Pin 1 and Pin 2 in close status. 00: Exit setting Interface Setting Exit the setting mode.
3-6. Operating Mode Description Operating mode Description ECO mode When the input voltage is within voltage regulated range, UPS will power the output directly from the mains. ECO is an abbreviation of Efficiency Corrective Optimizer. In this mode, when battery is fully charged, the fan will stop working for energy saving. Buck mode When the input voltage is higher than the when AC is voltage regulation range but lower than high normal. loss point, the buck AVR will be activated.

4. Troubleshooting If the UPS system does not operate correctly, please solve the problem by using the table below. Symptom Possible cause Remedy No indication and alarm even The AC input power is not Check if input power cord though the mains is normal. connected well. firmly connected to the mains. The AC input is connected Plug AC input power cord to AC input correctly. to the UPS output. EPO function is activated. Set the circuit in closed position to disable EPO function.
Symptom Fault code is shown as 14 on LCD display and alarm is continuously sounding. Fault code is shown as 01, 02, 03, 11, 12, 13 and 41 on LCD display and alarm is continuously sounding. Battery backup time is shorter than nominal value. Possible cause Remedy The UPS shut down Check output wiring and if automatically because short connected devices are in circuit occurs on the UPS short circuit status. output.
