NOTES:
1. Some older 5kW chargers do not have an LED.
2. During initial installation, the fan will completely discharge the ignition battery if utility power is not
available.
3. The ECM can be configured for 120 or 240 VAC line sense. Refer to Section 4.4 of the ECM Manual for details.
4. Each time the RAS switch is placed in Auto, a one minute self-test is performed.
5. ECM’s built after 12/99 use a flashing SYS LED in lieu of the COM LED for the “Heart Beat”.
6. The generator will not start unless a line failure is greater then 10 minutes.
7. The generator will start immediately and run for a minimum of 30 minutes (Use RAS to stop Gen).
8. The difference between any battery in the string should not exceed 0.3 Vdc under load (XMS2 self-test).
9. 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.
