3.1.2 UPS Testing
Test UPS: close the main input supply switch and start the UPS. Once
the UPS is operating normally and stay in inverter mode, check to
ensure the DC polarity and battery voltage is correct. If DC voltage and
polarity are correct, close the battery breaker. Disconnect the AC input
to simulate a power outage. The UPS will seamlessly switch to battery,
causing the on-battery alarm notification. Open the battery breaker to
simulate a battery low voltage condition. The UPS will switch to bypass
output, and the alarm will be constant.
Precautions for Operating UPS
• To prevent an OL condition, please be sure that the load is within
the capacity of the UPS.
•
Do not use the On/Off function of the UPS to turn on/off your load.
If UPS hasn’t been in use for a long period of time, the operational
prechecks will need to be repeated.
Operation
3.1.3 Start UPS
Please perform the following steps to start the UPS.
Step 1 Apply AC to the UPS.
Step 2 Close input supply breaker or disconnect.
If AC supply is within specs, Press the ON buttons on the panel for
1S, the rectifier will start automatically, 30S later, the DC bus voltage
increase to within spec, the rectifier indicator (AC/DC) on the panel will
be illuminated. The inverter will star after 10S, and 30s later, the output
voltage will supply any applied load.
Step 3 Close the external input switch of battery.
Check the polarity and voltage of battery is correct, if so, close the
battery switch.
