Safety and Installation Instructions
Connector pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H11
connector. Pin no. 26, the protective earth pin present on all
12H to 48H DC-DC converters is leading, ensuring that it
makes contact with the female connector first.
