Parallel Operation - INFOSEC E6 LCD 10K TM RM Manuel Utilisateur

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 cannot be cut off, you should remove the cover to maintenance bypass switch on
the rear panel and turn the maintenance switch to "BPS" position first.
3) Switch off the input breaker, and switch off the battery breaker (only available for long-run model).
4) Remove the cabinet and disconnect battery wire for standard model. Then modify the jumper of JS3 on control
board to set the battery numbers as following table.
NOTE: JS3 setting on the control board: please shorts the Pin1 & Pin2 for 18 pcs batteries; shorts the Pin3 & Pin4
for 19 pcs batteries; and shorts the Pin5 & Pin6 for 20 pcs batteries.
5) Switch on the 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 output voltage of each
UPS to check if the 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, 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 16,
section 3-7) in LCD setting to make sure the error 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.
