My windy discourse on shunts and meters was of a general nature, since this problem has come up before. Of course Neil is correct to advise following the Blue Sea instructions.

Since the panel in question has an analog ammeter/shunt, if the shunt power leads are hooked up backwards, the voltage drop across the shunt will be reversed and the meter will try to read negative and can't since it will hit the mechanical stop at just below zero. If the meter leads from the shunt are hooked backwards, the meter will also try to read negative. If both are hooked backwards, the meter will read correctly (two wrongs make a right?). So, if you see the meter try to read negative, the easiest thing to do is swap the meter leads, they're smaller. But if you hook to the instructions there should be no problem.
