Reverse Input Voltage Protection The input/output of this products is a non-isolated type and a step-down DC-DC converter from (+) polarity to (+) polarity. If you connect the input polarity reversed of this product by mistake it will be eventually damaged. If there is a possibility of reverse connection, please add a protection circuit as indicated in the following figure. The figure below is an example using fuse and diode.
