Multiple UPS parallel operation 

This section provides operating instructions for a UPS system containing 
multiple UPSs. 

 

  WARNING 

 

Do not use the internal Maintenance Bypass Switch (MBS) in UPSes 
that are installed as a parallel system. 

 

 

NOTE: Refer to the External Battery Cabinet Installation Manual for the 
EBC battery breaker location. 

Start and control the system wide function from UPS 1. 

7.4.1

 

Starting the parallel UPS in the bypass mode 

If the inverter output of the parallel UPS is not available and the critical 
load needs to be energized: 

 

  CAUTION 

 

In the bypass mode, the critical load is not protected from commercial 
power anomalies. 

1.

 

Make sure that the system maintenance bypass switch is open. 

2.

 

Close all UPS input feeder circuit breakers. 

3.

 

Close all module output breakers (MOBs). 

4.

 

If the UPSs are wired for dual input, close all of the UPS bypass 
input feeder circuit breakers. 

5.

 

Make sure that all the rectifier input switches are closed. 

6.

 

Make sure that all the bypass input switches are closed. 

7.

 

Make sure that all the output switches are closed. 

8.

 

Close the internal and external battery breakers. 

9.

 

Wait until the UPS control panel display becomes active and 
indicates logic power. 

10.

 

Check that there are no alarms active. 

11.

 

Select the CONTROLS symbol in the main menu bar. 
The System Control screen is displayed.
