5.5. Connect Devices to UPS
Once the UPS is connected to its AC source, connect load devices to
UPS.
1. Turn on the UPS first and then switch on the devices one by one,
the LCD panel will display total load level.
2. If it is necessary to connect the inductive loads such as a printer,
the inrush current should be calculated carefully to see if it meets
the capacity of the UPS to avoid overload.
3. If the UPS is in an overload state, the buzzer will beep twice every
second.
4. If the UPS is in an overload state, remove loads immediately. For
safety purposes, it is recommended that the total loads connected
to the UPS are less than 80% of its nominal power capacity.
5. If the overload time is over acceptable time listed in the spec at AC
mode, the UPS will automatically transfer to Bypass mode. After
the overload is reduced, it will return to AC mode. If the overload
time is over acceptable time listed in the spec at Battery mode, the
UPS will enter a fault status. At this time, if bypass is enabled, the
UPS will provide power to the load via bypass. If bypass function is
disabled or the input power is not within bypass acceptable range,
it will cut off the output of the UPS.
5.6. Charge the Batteries
1. After the UPS is connected to the utility power and the DC breaker
is closed, the charger will charge the batteries automatically except
in Battery mode or during battery self-test.
2. Suggest charge batteries at least 10 hours before use. Otherwise,
the backup time may be shorter than expected.
