I see in the electrical connection diagram in the user’s guide that there is a High PIV Ultra Fast switching diode. Do I need it and if so do you have a source?


This High PIV Ultra Fast switching diode prevents CEMF kick back from an intermediary relay coil when power is cut and the coil field collapses. You could use an On-Semi MUR105 diode or an IN4007, which is readily available.
