The rail gapping shown is for DCC turnouts, as well as DC. This will isolate the frog completely from the turnout and can be left un-powered but may cause some stalling on locomotives with short wheelbases.
Alternatively, you can power them from a relay, switch machine contacts, or the Hex Frog Juicer, which we strongly recommend. The gaps in the PC board ties shown on the templates must be there to prevent shorting in DC and DCC.
