Single Ups Operation - INFOSEC 5000 User Manual

3-4. Single UPS Operation

1. Turn on the UPS with utility power supply (in AC mode)
1) Once the power supply has been connected correctly, set the breaker of the battery pack to the
"ON" position (step only available for long-run model). Then set the input breaker to the "ON"
position. The fan is now running and the UPS supplies power to the loads via the bypass. The
UPS is operating in Bypass mode.
NOTE 1: When the UPS is in Bypass mode, the output voltage will be directly supplied by utility
power after you switch on the input breaker. In Bypass mode, the load is not protected by the UPS.
To protect your valuable devices, you should turn on the UPS. Refer to next step.
2) Press and hold the "ON" button for 0.5s to turn on the UPS and the buzzer will beep once.
3) A few seconds later, the UPS will switch to AC mode. If the utility power is abnormal, the UPS will
operate in Battery mode without interruption.
NOTE: If the UPS is shut down in Battery mode automatically and utility power is restored, the UPS will
start up and switch to AC mode automatically. When the UPS is running in battery, it will shut down
automatically in Battery mode. When the utility power is restored, the UPS will auto restart.
2. Turn on the UPS without the utility power supply (in Battery mode)
1) Make sure that the breaker of the battery pack is in the "ON" position (only for the long-run model).
2) Press and hold the "ON" button for 0.5s to turn on the UPS, and the buzzer will beep once.
3) A few seconds later, the UPS will come on in Battery mode.
3. Connect devices to UPS
After the UPS is turned on, you can connect devices to the 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 in-rush current should be
calculated carefully to see if it meets the capacity of the UPS, because the power consumption of
this kind of load may be too big.
3) If the UPS is in overload, the buzzer will beep twice every second.
4) If the UPS is in overload, please remove some loads immediately. It is recommended to have the
total loads connected to the UPS totaling less than 70% of its nominal power capacity to prevent
overload for system safety.
5) If the overload time is over the acceptable time listed in spec in AC mode, the UPS will
automatically transfer to Bypass mode. After the overload is removed, it will return to AC mode. If
the overload time is over the acceptable time listed in spec in Battery mode, the UPS will adopt
fault status. Then if bypass is enabled, the UPS will supply power to the load via bypass. If the
bypass function is disabled or the input power is not within the acceptable bypass range, it will cut
off output directly.
4. Charge the batteries
1) Once the UPS has been connected to the utility power, the charger will charge the batteries
automatically except in Battery mode or during the battery self-test.
2) Charging batteries for at least 10 hours before use is recommended. Otherwise, the backup time
may be shorter than expected time.
3) Make sure the battery numbers setting on the control panel (Please refer to the section 3-4-12 for
