Common Battery; External Battery Cabinet - Delta Ultron DPM Series User Manual

3.4 Common Battery (Only for Parallel UPSs Connected to
the Same External Battery Cabinet(s))
To save on your costs and installation space, the parallel UPSs can share their connected
external battery cabinet(s). For common battery application, please install a protective
device between each parallel UPS and its connected external battery cabinet(s). For
relevant information about the protective device, please refer to 5.5 External Battery
Cabinet Connection Warnings. Please see Figure 3-24 for two parallel UPSs sharing one
external battery cabinet as an example.
If the parallel UPSs share the external battery cabinet(s), you should use the LCD to set
up relevant parameters such as 'Battery Type', 'Battery Capacity', 'Battery Strings',
'Float Charge Voltage', 'Equalized Charge Voltage', 'Charge Current', etc. For more
information, please refer to 7.9.4 Battery Setting, 7.9.5 Charge Setting and 7.9.6 Parallel
Setting.
NOTE:
For common battery application, please use the LCD to 'Enable' common battery
function (please refer to 7.9.6 Parallel Setting), and set each UPS's battery setting
the same, charge setting the same, and charge current even. For example:
When (1) two UPSs are paralleled and share one external battery cabinet, (2) the
lead-acid batteries are used, (3) the battery capacity is 120AH, (4) there are a total
of 20 battery strings, and (5) the charge current is 240A, please use the LCD to set
each UPS's 'Battery Type' as 'Lead-acid', 'Battery Capacity' as 120AH, 'Battery
Strings' as 6, and 'Charge Current' as 120A.
