11. Operation and Operating Mode
2) New UPS input & output switch should be turned off, according to port sign, link
Input & output line and batteries; synchronously, remove the connection between
JP1 and JP2.
3) Turn off UPS system, when all UPS work at bypass model, please take apart every
UPS repaired board, turn all UPS repaired switches from ‘UPS’ to ‘BPS’ and then
turn off all UPS input switch.
4) If UPS system works at single UPS model, then have to remove the connection of
JP1 and JP2.
5) Take apart the board of parallel ports, insert one end of combine line into parallel
card’s slot and screw down its pin; and then lock up the board of parallel ports over
again; at the same time, take apart the maintain board of new UPS.
6) Turn on the battery switch of new UPS and line input connection switch outside;
measure voltage difference between output live wire of new UPS and output live
wire of parallel system. If the voltage difference
＜
1V, please close output live wire’s
witch of new UPS.
7) Take apart the board of parallel ports when UPS has turned to bypass mode, insert
the other end of combine line into parallel card’s slot and screw down its pin; and
then lock up the board of parallel ports over again
8) Close line input switch of all UPS(include new UPS) in the parallel system; lock up
maintain board, unless all UPS turn to bypass mode; press the open key in turn,
observe whether the display state of every UPS is normal; at the same time,
observe whether all UPS all together turn to inverter model; and measure the
voltage difference of every UPS ports’ JP2.
9) Turn off all UPS, take apart maintain board of all UPS unless they all have turned to
bypass mode. Turn all the maintain switches from “BPS” to “UPS” and lock up
every maintain board.
10) Turn on UPS, make all UPS changed into line inverter mode to work parallel.
Note: If the state of UPS is abnormal in step 8, please follow operational process of
removing single UPS to maintain.
