5.4Battery Operation
The separate battery manufacturer’s manual, available on the manufacturer’s Web site, provides the necessary information for the installation, operation and maintenance of the battery. Use the battery manual in conjunction with this manual.
The float charge voltage for a battery is equal to the number of cells in series making up the battery multiplied by the charge voltage for each cell.
Since the charging voltage level is critical to proper battery operation, refer to your battery manual, available on the manufacturer’s Web site, for information regarding your system.
For models with nominal 240 cell battery (High Link), the DC bus nominal float voltage range is 527 to 561 VDC. Maximum equalize voltage is 585 VDC. Battery voltage at end of discharge is 386 VDC at the UPS terminals (389 VDC at the battery). The number of battery cells required will range from 236 to 244, depending on your application.
