4.
When the UPS is Overloaded, remove some loads immediately. It is recommended to have
the total loads connected to the UPS equal less than 80% of the nominal power capacity to
prevent overload conditions.
5.
If the Overload time is over the acceptable time shown in the specification for AC Mode, the
UPS will automatically transfer to Bypass Mode. After the Overload is removed, the UPS will
return to AC Mode. If the Overload time is over acceptable time listed in the specification
for Battery Mode, the UPS will appear in Fault Status. At this time, if Bypass is enabled, the
UPS will power the loads via Bypass. If Bypass function is disabled or the input power is not
within Bypass range, the UPS will shut off output immediately.
Charging the Batteries
1.
After the UPS is connected to utility power, the charger will start to charge the batteries
automatically except if the UPS is in Battery Mode or during Battery Self-Test.
2.
It is suggested to charge the batteries at least 10 hours before use to assure proper backup
time.
3.
Make sure the battery number setting on the control board is consistent to the real
connection.
Battery Mode Operation
1.
When the UPS is in Battery Mode, the buzzer will beep according to battery capacity.
a.
If the battery capacity is more than 25%, the buzzer will beep once every 4 seconds.
b.
If the battery voltage drops to the alarm level, the buzzer will beep once every
second to indicate that the battery is at a low level and the UPS will soon shut down
automatically. Shutting down non-critical loads at this point will prolong the backup
time. If the programmable timer function is enabled, the UPS will shut off
programmable output terminals automatically.
Note:
There is a risk of data loss or load failure if battery runtime is exceeded.
2.
In Battery Mode, to silence the buzzer sound, press the Mute Button.
3.
The backup time depends on the external battery capacity.
4.
The backup time may vary depending upon environmental conditions and load types.
5.
When setting the backup time for 16.5 hours (default value from LCD panel), after
discharging for 16.5 hours, the UPS will shut down automatically to protect the battery. This
battery discharge protection can be enabled or disabled via the LCD Panel Control.
