Test the batteries

If you need to check the battery status or performance when the UPS is running in Line / Converter / ECO
mode, you could enter ”Control->Batt Test” to instruct the UPS to perform a battery test. Please refer to
the section of “LCD Operation”.

Users also can set battery test through monitoring software.

Turn off the UPS with utility power supply in Line mode
1.
When LCD is on home page, press the “OFF/ESC” button, LCD will show a prompt page of “Turn
Off”; Move the arrow to “Yes” by up or down button, then press “ON/ENTER”, the UPS will beep
once and turn off. Power is still applied via bypass mode. You could also enter the “control menu” to
select the instruction “Turn Off” to turn off the UPS. Please refer to the section of “LCD operation”.
Note:
Here, “Turn Off” means that UPS is not working on line / converter / ECO / battery / battery test
mode. So even though the UPS is turned off, if input or bypass voltage is normal, the internal power sup
-
ply will still be working; and if bypass status has been set to “enable”, the output voltage of the UPS will
still exist.

If you need to fully cut off the output, switch off the external input breaker. A few seconds later, there is
no display shown on the panel and UPS is completely off.
