7. MAINTENANCE
7.1. Preventative maintenance
Preventative maintenance of the UPS system can guarantee reliability and a long-time service. Run some tests per month as
follows:
7.1.1. Shut down the UPS (in respect of the operation steps for the details).
7.1.2. Check that the vents are not blocked.
7.1.3. Check if there is too much dust covering the surface.
7.1.4. Check if the plug connections of input, output and batteries are firm, and if the cable insulation is intact.
7.1.5. Make sure that the UPS is not steaming.
7.1.6. Start the UPS (in respect of the operation steps for the details).
7.1.7. Let the UPS working during 5 minutes on battery mode and with a small test load – until the alarm sounds
because of low battery voltage. Whilst this period should appear no other alarm information; if it does happen:
contact the local service centre or the supplier.
7.2. Battery maintenance
This unit uses a sealed lead-acid battery. The life time can be reduced because of bad environment conditions, frequent
discharges and sharp temperature increase. The performance of the battery can degrade gradually even when it is not used.
Therefore we advise to discharge them every 3 months if no mains failure situation occurs for a long time.
Follow the steps below for the maintenance:
The performance decreases rapidly. Keep in mind the following work operations of battery maintenance.
7.2.1. Connect the input main power, switch on the UPS and charge the battery during 8 hours. Supervise the running
status of loading which is connected to the UPS.
7.2.2. Keep the load connected and take note of the total output power. Then cut the main power supply off. The
UPS transfers automatically to battery mode before shutting down. Take note of the discharging time in order to
refer it later.
The total of the load (current consumption) is calculated in the unit «Watt».
If the marking on the UPS just shows the power capacity in the unit «VA», then multiply the VA rating with
the power factor (PF = 0.6) for calculating the rating of «Watt».
7.2.3. Under normal usage conditions, the battery lifetime is approximately 1-2 years. But when the battery
temperature and the discharging frequency are high, then the lifetime is approximately 0.5-1 years.
7.2.4. The performance of the battery degrades respectively to its running time. When the discharging time goes
down to be 80% of its initial time, the performance is degrading quickly. Therefore the battery maintenance should
be done every month.
7.2.5. The battery maintenance of UPS units with long backup:
(Regular maintenance is vital for the protection of precision equipment under main power off condition.)
Clear the dust on the battery.
Check if the connecting cables between the batteries are loose or not. When necessary replace the cable
or even the battery.
Keep the cable connection to the battery tight.
Note: The discharging test above is just a simple test to check charging status and performance of the battery. Contact the
local battery supplier for more detailed information about the battery charging status.
7.3. Troubleshooting
The UPS can offer a reliability for the load. In the case of abnormal perturbations it is advisable to contact a local service
centre to prevent and avoid more damage and nonessential costs. When the UPS is in abnormal status, you can refer to the
following trouble shootings. But if the problem cannot be solved, contact the local distributor or contact our company
directly.
