Note.2

Note

1. All parameters not specially mentioned are measured at 230VAC input, rated load and 25

of ambient temperature.

2. The charger is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC

directives.

3. Before charging, make sure the battery charger and battery specifications are compatible.

4. When using sleep mode, please refer to charging current vs. Ambient temperature de-rating curve.

5. Optional Remote Controller (CR-1).
