Manual test of the UPS
Manual UPS or Manual Battery tests can be conducted from the UPS configuration as well and are functional even
when the UPS is not charging the battery.
Manual Battery test: Scroll the parameters until Manual Bat test displays on the LCD.
Press the button twice.
**) Note: In order for the UPS and power management software to operate normally, Manual Bypass should
always be set to OFF as the load will not be protected by the unit when Manual Bypass is ON. This is aimed for
operating an external maintenance bypass switch.
***) Note: You should turn UPS off and keep the AC power before you use “Generator” function. (even you want
to select “\Generator\OFF” to back to normal mode).

• If UPS is on battery and the ON BATTERY LED is on, UPS will beep every 5 seconds.
• If the battery capacity is low and the ON BATTERY LED is flashing, the UPS will beep twice every 5 seconds.
• If UPS is on bypass and the BYPASSED LED is on, UPS will no beep.
• If UPS has an internal fault and the ALARM LED is on, the UPS will give a constant audible alarm displaying
the cause on the LCD display.
Silencing an Alarm
By pressing any of the three buttons on the front panel, the alarm can be turned off, except when the battery is
low, which will cause the alarm to resound.
On the LCD display, you can also choose silent alarm mode which will not warn you of any malfunction audibly.
