10.4 Maintenance Of UPS And Options
UPS and the options need common maintenance:
1. Keep good history record. Keeping good history record facilitates failure treatment.
2. Keep clean, so as to prevent UPS from the invasion of dust and moisture.
3. Maintain appropriate ambient temperature. The most appropriate temperature for battery is 20
°
C to 25
°
C.
Too low temperature will reduce the battery capacity and too high temperature will reduce the battery life.
4. Check the wiring. Check the tightening of all connected screws, and there should be routine tightening at
least once a year.
5. Check regularly if there is any abnormity in the superior or subordinate switch to ensure cutting off the
import or export when the current is too large. Maintenance staff should be familiar with the typical ambient
conditions where UPS is working in order to rapidly position which ambient conditions are unusual; the setting
of UPS operation control panel should be known as well.
For information of the UPS battery maintenance, refer to
6.5 Battery Maintenance .
