Chapter 7: Maintenance

z
UPS Cleaning:
Regularly clean the UPS, especially the slits and openings, to ensure that the air freely flows
into the UPS to avoid overheating. If necessary, use an air-gun to clean the slits and openings
to prevent any object from blocking or covering these areas.
z
UPS Regular Inspection:
Regularly check the UPS every half year and inspect:
1. Whether the UPS, LED, or alarm function has any abnormality.
2. Whether the UPS works in bypass mode (normally, the UPS will work in on-line mode). If
yes, check if any error, overload, internal fault, etc. occurs.
3. Whether battery voltage is normal. If battery voltage is too high or too low, find the root
cause.
The RT series UPS uses sealed lead-acid batteries. The battery life depends on the temperature, the
usage, and charging/ discharging frequency. High temperature environments and high charging/ dis-
charging frequency will quickly shorten the battery life. Please follow the suggestions below to ensure a
normal battery lifetime.
z
Keep the usage temperature between 15°C~25°C (59°F~77°F).
z
When the UPS needs to be stored for an extended period of time, the battery must be re charged
once every three months and the charging time must not be less than 24 hours each time.
The higher the temperature, the shorter the fan life is. When the UPS is running, please check if the
fan(s) works normally and make sure UPS is ventilated properly. If not, replace the fan.
NOTE:
Please ask your local dealer or customer service for more maintenance information. Do
not perform maintenance if you are not trained for it
