Single Ups Operation - Phasak PH 9280 Manual De Uso

3.5. Single UPS Operation

1. Turn on the UPS with utility power supply (in AC mode)
1) After power supply is connected correctly, set the breaker of the battery pack at "ON" position (the step only available
for long-run model). Then set the input breaker at "ON" position. At this time the fan is running and the UPS enter to
power on mode for initialization, several seconds later, UPS operates in Bypass mode and supplies power to the loads
via the bypass.
NOTE: When UPS is in Bypass mode, the output voltage will directly power from utility after you switch on the input
breaker. In Bypass mode, the load is not protected by UPS. To protect your precious 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 enter to AC mode. If the utility power is abnormal, the UPS will operate in Battery
mode without interruption.
NOTE: When the UPS is running out battery, it will shut down automatically at Battery mode. When the utility power is
restored, the UPS will auto restart in AC mode.
2. Turn on the UPS without utility power supply (in Battery mode)
1) Make sure that the breaker of the battery pack is at "ON" position (only for long-run model).
2) Press the "ON" button to set up the power supply for the UPS, UPS will enter to power on mode. After initialization
UPS will enter to No Output mode, then 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 be turned on and enter to 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 loads is too big.
3) If the UPS is overload, the buzzer will beep twice every second.
4) When the UPS is overload, please remove some loads immediately. It is recommended to have the total loads
connected to the UPS less than 80% of its nominal power capacity to prevent overload for system safety.
5) If the overload time is over acceptable time listed in spec at 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 acceptable time listed in
spec at Battery mode, the UPS will become fault status. At this time, if bypass is enabled, the UPS will 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
output directly.
4. Charge the batteries
1) After the UPS is connected to the utility power, the charger will charge the batteries automatically except in Battery
mode or during battery self-test.
2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may be shorter than expected
time.
3) Make sure the battery numbers setting on the control board (Please refer to the section 3-4-12 for detailed setting) is
consistent to real connection.
