To choose the type and number of batteries needed for 24, 60, or 72 hours of standby power based on the
Amp Hours Required calculation from the XR2500F Power Requirements section, perform the following:
1. Select the desired standby hours required from the table below: 24, 60, or 72 hours
2. Select the desired battery size: Model 368 (12 VDC 4.5 Ah), Model 369 (12 VDC 7 Ah),
1. Select the desired standby hours required from the table below: 24, 60, or 72 hours
2. Select the desired battery size: Model 368 (12 VDC 4.5 Ah), Model 369 (12 VDC 7 Ah),
Model 367 (12 VDC 7.7 Ah), Model 365 (12 VDC 9 Ah), Model 366 (12 VDC 18 Ah).
3. Select a Max. Ah Available number that is just greater than the number calculated as the Amp Hours
Required.
4. Install the number of batteries shown in the corresponding No. of Batteries required column.
Example: If the Amp Hours Required calculation equals 22 Ah for 24 hours of standby time and 4.5 Ah
Example: If the Amp Hours Required calculation equals 22 Ah for 24 hours of standby time and 4.5 Ah
batteries are desired, install six (6) Model 368 (12 VDC, 4.5 Ah) batteries.
For listed installations, all batteries shall be installed in a DMP Model 341, 349, 350, or 352S enclosure
