Command
(initiate, stop
battery, system
test or freshening
charge
Battery maintenance test
This test performs a partial discharge of the battery to obtain a rough estimate
of the battery capacity. Load must be between 20% and 80%
Battery capacity test
This test performs a full discharge of the battery to obtain a precise measure of
the battery capacity. Load must be between 20% and 80%
System test
This is a self-test of the UPS. When the user activates this function, a window
appears about five seconds later to show the test result
Stop testing Manually stops a battery maintenance test, battery capacity test or system test
Freshening charge Manually initiates a battery freshening charge
Stop freshening charge Manually stops a battery freshening charge

Table 5-8 Prompts and meanings
Prompt Meaning
Transfer with interrupt, confirm or
cancel
The inverter and bypass supplies are not synchronized and any load transfer between
the inverters and bypass will cause a brief load interruption
The load is too high to be transferred
with interrupt
The total load must be less than the capacity of one UPS to allow a parallel system to
perform an interrupted transfer from bypass to inverter
This operation leads to output
shutdown, confirm or cancel
The bypass is abnormal, turning off the inverters will cause the load to be
dis-engergised
This operation leads to inverter
overload, confirm or cancel
Turning off this inverter will lead to the overload of the remaining inverter(s) in a
parallel system
Turn on more UPS to carry current
load
The number of inverters already turned on is insufficient to carry the exisitng load. The
user is required to turn on more inverters
Battery will be depleted, confirm or
cancel
If you select battery maintenance test, the battery will discharge until the UPS shuts
down. This prompt appears to require your confirmation. Cancelling the test will ends
the test and transfers the UPS to Normal mode
System self test finished, everything is No action required
