NOTES:
.
1. During initial installation, the fan will completely discharge the ignition battery if utility power is not available.
2. Verify via status monitoring.
3. Each time the RAS switch is placed in Auto, a one minute self-test is performed.
4. The generator will not start unless a line failure is greater then 10 minutes.
5. The generator will start immediately and run for a minimum of 30 minutes (Use RAS to stop Gen).
6. The difference between any battery in the string should not exceed 0.3 Vdc under load (XMS2 self-test).
7. Typical battery pack voltage ranges are 39.6-42.3Vdc, 52.8-56.4Vdc, and 105.6-112.8Vdc for 36/48/96 volt systems, respectively.
