3.6.5   Setting Parameters Of Double Bus System 

Take the double bus system formed by the 1 + 1 parallel system for example, set ‘System Configuration’ to ‘Parallel’, 
‘Parallel requisite units’ to ‘1’, ‘Parallel Redundant Units’ to ‘1’. For the master system, set ‘LBS Function’ to 
‘MASTER’. For the slave system, set ‘LBS Function’ to ‘SLAVE’. Ensure that the setting for ‘3 Phase Output or 1 
Phase Output’ of each single UPS in the double bus system is same, as shown in Figure 3-11.
