3) A few seconds later, the UPS will be turned on and enter to Battery mode.

3. Connect devices to UPS
After the UPS is turned on, you can connect devices to the UPS.
1) Turn on the UPS first and then switch on the devices one by one. The LCD panel will display total load level.
2) If it is necessary to connect the inductive loads such as a printer, the in-rush current should be calculated carefully to see if it meets the capacity of the UPS, because the power consumption of this kind of loads is too big.
3) If the UPS is overload, the buzzer will beep twice every second.
4) When the UPS is overload, please remove some loads immediately. It is recommended to have the total loads connected to the UPS less than 80% of its nominal power capacity to prevent overload for system safety.
5) If the overload time is over acceptable time listed in spec at AC mode, the UPS will automatically transfer to Bypass mode. After the overload is removed, it will return to AC mode. At this time, if bypass is enabled, the UPS will power to the load via bypass. If bypass function is disabled or the input power is not within bypass acceptable range, it will cut off output directly. If the overload time is over acceptable time listed in spec at Battery mode, the UPS will become fault status.

4. Charge the batteries
1) After the UPS is connected to the utility power, the charger will charge the batteries automatically except in battery mode or during battery self-test or overload or battery high voltage.
2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may be shorter than expected.

5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will sound according to different battery capacity. If the battery capacity is more than 25%, the buzzer will beep once every 4 seconds. If the battery voltage drops to the alarm level, the buzzer will beep quickly (once every sec) to remind users that the battery is at low level and the UPS will shut down automatically soon. Users could switch off some non-critical loads to disable the shutdown alarm and prolong the backup time. If there is no more load to be switched off at that time, you have to shut down all loads as soon as possible to protect the devices or save data. Otherwise, there is a risk of data loss or load failure.
2) In Battery mode, users can touch “SETTING” “Basic” Audio Mute to enable “Mode Mute” to disable the buzzer.
3) The backup time of the long-run model depends on the external battery capacity.
4) The backup time may vary from different environment temperature and load type.
5) When backup time is displayed as 16.5 hours (default value), after discharging 16.5 hours, UPS will shut down automatically to protect the battery.

6. Test the batteries
1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode, you could touch “CONTROL” and select “Battery Test”. Refer to “Battery Test” screen.

3-5. Parallel Operation
1. Parallel system initial startup
Please make sure that all of the running UPSs are parallel models and have the same configuration. 1) Turn on each UPS in AC mode respectively (Refer to section 3-4(1)). Then, measure the inverter
output voltage of each phase for each UPS with a multi-meter. Calibrate the inverter output voltage by configuring inverter voltage adjustment (Refer to SETTING Advance Maintainer VOL CALI Inverter CALI screen) in LCD menu until the inverter output voltage difference of each UPS is within 1V or less. 2) Turn off each UPS (Refer to section 3-4(7.)). Then, follow the wiring procedure in section 2-4. 3) Remove the cover of parallel share current cable port on the UPS, connect each UPS one by one with the parallel cable and share current cable, and then screw the cover back. 4) Turn on the parallel system in AC mode: a) Turn on the line input breaker of each UPS and turn on bypass input breaker). After all UPSs
enter to bypass mode, measure the output voltage between two UPSs for the same phase to make sure the phase sequence is correct. If these two voltage differences are near to zero, that means all connections are met. Otherwise, please check if the wirings are connected correctly. b) Turn on the output breaker of each UPS. c) Turn on each UPS in turns. After a while, the UPSs will enter to AC mode synchronously and then, the parallel system is now complete. 5) Turn on the parallel system in Battery mode: a) Turn on the battery breaker and output breaker of each UPS. b) Turn on any UPS. A few seconds later, the UPS will enter to battery mode. c) Turn on another UPS. A few seconds later, the UPSs enter to Battery mode and add to the parallel system. d) If you have the third UPS, follow the same procedure of c). Then, the parallel system is complete. If you would like to have more information regarding the parallel operation, please contact your supplier or service center for detail parallel operation instruction.
2. Add new units into the parallel system
1) You can’t add one new unit into the parallel system when whole system is running. You must cut off the load and shutdown the system.

5-2. Maintenance

The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified maintenance personnel.
Even after the unit is disconnected from the mains, components inside the UPS system are still connected to the battery packs which are potentially dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no current is present and no hazardous voltage exists in the terminals of high capability capacitor such as BUS-capacitors.
Only persons are adequately familiar with batteries and with the required precautionary measures may replace batteries and supervise operations. Unauthorized persons must be kept well away from the batteries.
Verify that no voltage between the battery terminals and the ground is present before maintenance or repair. In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages may occur between the battery terminals and the grounding/earthing.
Batteries may cause electric shock and have a high short-circuit current. Please remove all wristwatches, rings and other metal person objects before maintenance or repair, and only use tools with insulated grips and handles for maintaining or repairing.
When replace the batteries, install the same number and same type of batteries.
Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The batteries must be deposed according to local environmental regulations.
Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may be toxic.
Please replace the fuse only with the same type and amperage in order to avoid fire hazards.
Do not disassemble the UPS system.
