The docs. pertaining to my HDX-555 with MCL100 Limit Switch package 
include a section headed "1 HP wiring for 220V":

	"Black T4
	Tape T2 & T3
	Tape P2
	White P1
	Green T5
	Red T8"

-- where Tx and Px refer to terminals on the motor. There is no mention 
of changes to other wiring.

NOTE: I cannot guarantee that the above connections do in fact apply to 
your motor and control system. If you blow them up, it's not my fault.
