Notes

1. De-rate by 12% if mounted in portrait orientation.

2. With 4% engine governing.

3. After 2 minutes.

4. Generator de-rate may apply. Check with factory.

5. Factory set, semi-sealed, jumper selectable.

6. Any device connected to the analogue input must be fully floating(galvanically isolated form ground), with an insulation strength of 500V ac

7. De-rate output current by 5% per degree C above 60C.

8. Non condensing
