Chapter 9: Maintenance - Delta Ultron HPH Series User Manual

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 a vacuum cleaner 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. Regularly check, clean or replace the filters according to the UPS using environment, to avoid
UPS overheating.
b. Regularly check the UPS every half year and inspect:
1) Whether the UPS, tri-color LED indicators, and any warning message.
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 battery voltage is normal. If the battery voltage is too high or too low, find the root
cause.
Batteries
The HPH Series UPS uses sealed lead-acid batteries. The battery life depends on the environment
temperature, the usage, and the charging/ discharging frequency. High temperature environments
and high charging/ discharging frequency will quickly shorten the battery life. Please follow the
suggestions below to ensure a normal battery lifetime.
 Keep the usage temperature at 15°C ~25°C.
 When the UPS needs to be stored for an extended period of time, the batteries must be
recharged once every three months and the charging time must not be less than 24 hours
each time.
NOTE:
1. If the batteries need to be replaced, please contact qualified service personnel.
During battery replacement, the loads connected to the UPS will not be protected if
input power fails.
