YES YES YES!!! THAT WOULD DO IT!
So add a Pack voltage +72 to that pin and things should be happy!
You can use a 12 volt Automotive relay to activate the 72 volts to the Pin1 if you want, that's what I used when I had 60 volt contactor coils before I got my hands on the bigger SW200 ones. I had a relay run off my ignition switch to turn on the contactors, then turn on the controller.
