Chapter 7 Maintenance
This chapter introduces UPS maintenance, including the maintenance instructions of power module,
monitoring bypass module and the change method of dust filter.
7.1 Instruction of Maintenance Operation
7.1.1 Precautions
1.
Only maintaining engineers can do this job.
2.
In principle, the broken elements should be disassembled from top to bottom, so as to prevent any
inclination from high gravity centre of the cabinet.
3.
To ensure the safety before maintaining power module and bypass module, be sure to use a
multimeter to measure the DC bus capacitor voltage and ensure the voltage is below 60V before
operation, and use a multimeter to measure the voltage between operating parts and the earth to
ensure the voltage is lower than hazardous voltage, i.e. DC voltage is lower than 60Vdc, and AC
maximum Voltage is lower than 42.4Vac.
4.
Only after 10 minutes removing the power components and bypass components, the maintenance
can be carried out.
7.1.2 Instruction to Bypass Module
Suppose UPS were in normal mode, and the bypass were normal:
1.
Select manual switch of bypass in LCD screen, the UPS power will be supplied by bypass.
2.
Close maintenance bypass switch, the UPS power will be supplied by maintenance bypass.
3.
Open UPS output switch and input switch.
4.
Open external battery switch and internal battery switch.
5.
Take the door sheet of UPS off, remove and repair the damage components,
6.
Reinstall the corresponding components in the cabinet after maintenance, reinstall the internal door
sheet, and complete connection of the flat cables at the front of the internal door.
7.
Close the bypass switch of UPS and switch the rotary switch to UPS output.
After 5 seconds, the indicator light of the operating control display panel works, which shows the
power is normally supply by the bypass.
8.
Open maintenance bypass switch and close mains input switch, the inverter automatically starts,
and UPS operates in the normal mode after 60 seconds.
9.
Close external battery switch or internal battery switch, the battery light on the panel turns off,
which show connection with the battery; inspect the battery voltage is normal or not which is shown
on the panel.
