UPS
•
1. 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 replace the filters regularly to prevent any object from blocking
or covering these areas.
2. UPS Regular Inspection:
a. Monthly check the filters and regularly replace them.
b. Regularly check the UPS every half year and inspect:
1) Whether the UPS and its LED indicators and alarm operate 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.
Batteries
•
The DPS series UPS uses the lead-acid batteries or the lithium-ion batteries. Make sure
to replace the batteries according to battery life. However, the actual battery life depends
on the environment temperature, usage, and charging/ discharging frequency. High
temperature environments and high charging/ discharging frequency will quickly shorten
battery life. Please follow the suggestions below to ensure normal battery life.
1. Keep usage temperature between 15°C ~ 25°C (59°F ~ 77°F).
2. When the UPS needs to be stored for an extended period of time, the lead-acid
batteries must be recharged once every three months and the charging time must
not be less than 24 hours each time. As for the lithium-ion batteries, please contact
your battery supplier for the charging frequency and charging duration.
Fans
•
Higher temperatures shorten fan life. When the UPS is running, please check if all of the
fans work normally and make sure there is good ventilation around and through the UPS. If
not, replace the fans.
NOTE:
Please ask your local dealer or customer service for more maintenance
information. Do not perform maintenance if you are not trained for it.
