Parallel UPS Installation and Commissioning 

Liebert NXC 

3) The rectifier runs in normal mode about 30 seconds, the rectifier start-up is finished.   

4) Finish and check the parallel parameter settings. 

5) Press the ON button for 2 seconds, the inverter indicator (green) are blinking, the inverter starts, and the inverter indicator 
turns green. 

6) If the battery is not connected, the fault indicator is blinking. If the battery is connected, the fault indicator turns off. 

7) If the UPS is working normally, turn off the UPS. 

8) Repeat the preceding step1) ~ setp7) to power on and commission the other UPSs respectively. 

Note 

Carry out the parallel commissioning after each UPS is working normally. 

 
Confirm that each UPS has been powered on and working normally, commission the parallel system, the specific procedures are 
as follows: 

1) Close the external output MCB and input MCB and the corresponding UPS internal LBSs of one UPS. The UPS is powered on 
and enters Bypass mode. The rectifier starts. Press the ON button for 2 seconds, the inverter indicator turns on. Measure 
whether the inverter output voltage is normal. 

2) Close the external output MCB and input MCB and the corresponding UPS internal LBSs of the second UPS. Follow the 
preceding steps to start the inverter of the second UPS, check whether there is alarm on the LCD, and confirm that the UPS 
parallel works normally. 

3) Follow the methods to start up the inverter of the third or fourth UPS to connect the UPS into the parallel system. 

Waring 

During the parallel system power-on, confirm that the external output MCB of each UPS has been closed, and that all the inverter 
output of the UPSs are connnted parallelly.

Installation And Commissioning For Double Bus System with common 

neutral 

3.5.1

 

Introduction 

The double bus system consists of two independent UPS systems; each UPS system consists of one or two parallel-connected 
single UPSs, or more parallel-connected single UPSs. 

The double bus system has high reliability, which is suitable for the load with dual input terminals. For single UPS input load, you 
can add a static transfer switch (STS, optional) to start the standard Load Bus Synchronization (LBS) system. 

Place the UPSs side by side, and connect the UPSs as following: 

The double bus system uses the LBS system to realize the output synchronization of the two independent (or parallel) UPS 
systems. One is the master system, and the other is the slave system. The operation mode of the double bus system contains 
master system and/or slave system running in normal mode or bypass mode. The schematic diagram of the LBS system built by 
1 + 1 parallel system is shown in Figure 3-8.
