Preventative Maintenance
Preventive Maintenance ensures the longer Service life of UPS. Please check the following steps every month:
- Turn off the UPS;
- Make sure the air grid is not blocked;
- Make sure that the UPS surface is not covered by dust;
- Check whether the input and output connectors are firmly connected
- Make sure that the UPS is not affected with damp;
- Turn on the UPS;
- Let the UPS work in battery mode for about 5 minutes. If there is no other alarm in this period, then the UPS is working normal; if there is another alarm message, please contact the local dealer for help.
Battery Maintenance
The UPS contains a sealed lead-acid maintenance-free battery (batteries). Bad environmental conditions, to high discharge frequency, to high temperature, etc will dramatically reduce the battery life. The battery life will also reduce even if it is not used. It is suggested to discharge the battery once every 3 months when AC is normal. The following steps explains how to check the battery. When the battery is near the end of its life, the battery will end in bad performance. So, please remember the following steps of checking and maintenance:
- Connect the UPS to AC and turn on the UPS, charge the battery for at least 10 hours. Do not attach any load to the UPS while charging.
- Connect any load to the UPS (UPS and Surge outputs) and remove the input plug from the UPS to simulate AC failure. The battery of the UPS will discharge until the UPS turns off automatically.
- Please record the connected load and discharge time for a later check.
- When the discharge time is 80% of the initial discharge time, the performance of the battery will be weakened faster and accordingly the checking frequency of the battery should be changed to every month.
