WARNING	As a safety feature, interlock 2 pins (39 and 59) on Bank 2 must be
	shorted to enable the Bank 2 Analog Bus relays to close. The
	optional 34924T terminal block shorts these pins for you. This
	feature protects inadvertent routing of high voltages from the
	Analog Buses to the D-sub connector of the module.
