Parallel System And LBS System 

This chapter provides a detailed description of the parallel system and LBS system installation procedures. 

8.1 

 

General 

The parallel system may include up to four UPS modules of the same power rating connected in parallel, without 
the  need  for  a  centralized  mains  static  bypass.  The  load  is  shared  by  the  bypass  static  switches  of  each  UPS 
when the system switches to the mains bypass supply. 
From a 'power' viewpoint, each module is internally identical to the 'single module' configuration. A parallel system 
requires  inter-module  control  signals  to  manage  the  load  sharing,  synchronizing  and  bypass  switching.  The 
control signals are connected via the parallel cables, which are multi-way ribbon cables connected between the 
units in the system so as to form a ring. 
When  two  or  more  modules  are  to  be  connected  in  parallel,  we  recommend  installing  an  inductor  on  the  static 
bypass line. This can be installed inside the UPS as an option. 

8.2 

 

System Installation Procedures 

The basic installation procedure for a parallel system is the same as that for single module system. This section 
only covers the installation procedures that are specific to the parallel system. To install a parallel UPS system, 
carry  out  the  installation  procedure  for  a  single  UPS  module,  plus  the  additional  operations  described  in  this 
section. 

8.2.1 

 

Preliminary Checks 

Make  sure  that  the  parallel  cable  options  are  correct,  and  that  the  modules  are  identical  (same  rating,  same 
model and same software and hardware release). 

Warning 

In order to ensure that the various modules installed in a parallel system are coordinated correctly, each 
module must be configured individually by Vertiv service personnel using the Vertiv configuration software. 

 
8.2.2 

 

Installing the Cabinets 

Place the UPS modules side by side and interconnect them as shown in Figure 8-1. The output distribution mode 
(Q1EXT, Q2EXT must be configured) shown in Figure 8-1 is recommended in order to facilitate maintenance and 
system testing.
