13.1 UPS
 UPS Cleaning
Regularly clean the UPS, especially the slits, openings and filters, to ensure that the air freely flows
into the UPS to avoid overheating. If necessary, use an air blower to clean the slits and openings,
and clean and replace the filters regularly to prevent any object from blocking or covering these
areas.
 UPS Regular Inspection
a. Monthly check the filters, and regularly clean and replace them.
b. Regularly check the UPS every half year and inspect:
1) Whether the UPS, LED indicators, and alarm function are operating normally.
2) Whether the UPS works in bypass mode (normally, the UPS works in normal mode). If yes,
check if any error, overload, internal fault, etc. occurs.
3) Whether the battery voltage is normal. If the battery voltage is too high or too low, find the
root cause.
13.2 Batteries
The RT 10/ 15/ 20kVA UPS uses lead-acid, lithium-ion, or other batteries. Make sure to replace the
batteries according to the battery lifetime. However, the actual battery lifetime depends on the
environment temperature, usage, and charging/ discharging frequency. High environment
temperature and high charging/ discharging frequency will quickly shorten the battery lifetime.
Battery inspection and maintenance are required periodically. Please follow the suggestions below
to ensure a normal battery lifetime.
 Keep the usage temperature at 20°C ~ 25°C (68°F ~ 77°F).
 Idle lead-acid batteries must be fully recharged (for at least 24 hours) every three months if
the UPS needs to be stored for an extended period of time. As for lithium-ion batteries and
other batteries, please contact your battery vendor for the information. Regardless of battery
type, please fully charge the batteries until the battery percentage shown on the LCD is 100%
( ).
