11. Operation in Fault mode
1)
When Fault LED lights up and the buzzer beeps continuously, it means that there is a fatal error in the UPS.
Users can see the fault code on the display panel. Please check the trouble shooting table in chapter 4 for
details.
2)
Please check the loads, wiring, ventilation, utility power, battery power and so on after the fault occurs. Do not
try to turn on the UPS again before solving the problems. If the problems cannot be fixed, please contact the
distributor or service people immediately.
3)
In an emergency situation, please cut off the connection to utility power, external battery, and output
immediately to avoid further risk or danger.
12. Battery number changing operation
1) This operation is only available for professional or qualified technicians.
2) Turn off the UPS. If the load couldn’t be cut off, you should remove the cover of maintenance bypass switch
on the rear panel and turn the maintenance switch to “BPS” position first.
3) Switch off the line input breaker(for dual input unit, also switch off the bypass input breaker), and switch off
the battery breaker (only available for long-run model).
4) Remove the cabinet cover, and disconnect battery wire for standard model. Then modify the jumper of JS3
on the control board to set the battery numbers as following table.
Note:1 = connect with jumper; 0 = no jumper; x = the pins are for other functions.
5)
Modify the battery pack for the setting number carefully. After complete it, put the cover back, switch on the
battery breaker for long-run model.
6) Switch on the line input breaker(for dual input unit, also switch on the bypass input breaker) and the UPS
will enter Bypass mode. If the UPS is in maintenance Bypass mode, turn the maintenance switch to “UPS”
position and then turn on the UPS.
3-5. Parallel Operation
1. Parallel system initial startup
First of all, please make sure all of the UPSs are parallel models and have the same configuration.
1) Turn on each UPS to AC mode respectively (Refer to section 3-4(1)). Then, measure the inverter output
voltage of each phase for each UPS to check if the inverter voltage difference between actual output and
setting value is less than 1.5V (typical 1V) with multimeter. If the difference is more than 1.5V, please
calibrate the voltage by configuring inverter voltage adjustment (Refer to Program 15, 16 and 17, section 3-7)
in LCD setting. If voltage difference remains more than 1.5V after calibration, please contact your local
distributor or service center for help.
2) Calibrate the output voltage measurement by configuring output voltage calibration (Refer to Program 18, 19,
and 20, section 3-7) in LCD setting to make sure the difference between real output voltage and detected
value of UPS is less than 1V.
3) Turn off each UPS (Refer to section 3-4(7.)). Then, follow the wiring procedure in section 2-4.
4) 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.
