Recommendations and Precautions

1. Ensure that the input voltage is within the allowable input voltage range of the DC-DC converter.
2. The converter is not equipped with an HV input fuse. It is recommended that the module be equipped with 15A / 600V fuse at the HV battery when using the module.
3. Ensure that the input polarity is correct before connecting to the HV battery.
4. Ensure that the output polarity is correct before connecting to the 12V auxiliary battery.
5. The output side of the DCDC converter must be connected to a 12V auxiliary battery in order to operate.
6. Do not mix or reverse the input and output wires.
7. Avoid hot plugging the HV connector to avoid arcing. Due to the high power, make sure that the HV input connector is firmly connected before turning on the main power switch or contactor on the high-voltage side.
8. Recommended to disconnect 12v positive output from the 12V auxiliary battery when DCDC is powered down. Options include use of a KSI or other relay of adequate current.
