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.
2) In Bypass mode, output voltage of the UPS is still present. In order to cut off the output, switch off the line input breaker(for dual input unit, also switch off the bypass line breaker). A few seconds later, there is no display shown on the display panel and UPS is complete off. 8. Turn off the UPS without utility power supply in Battery mode 1) Turn off the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will beep once.
3-5. Parallel Operation 1. Parallel system initial startup First of all, please make sure all of the UPSs are parallel models and have the same configuration. 1) Turn on each UPS to AC mode respectively (Refer to section 3-4(1)). Then, measure the inverter output voltage of each phase for each UPS to check if the inverter voltage difference between actual output and setting value is less than 1.5V (typical 1V) with multimeter. If the difference is more than 1.
Second method: 1) If the bypass is abnormal, you can not remove the UPS without interruption. You must cut off the load and shut down the system first. 2) Make sure the bypass setting is enabled in each UPS and then turn off the running system. All UPSs will transfer to Bypass mode. Remove all the maintenance bypass covers and set the maintenance switches from “UPS” to “BPS”. Turn off all the input breakers and battery breakers in parallel system.
