As a safety feature, interlock 1 pins (39 and 59) on Bank 1
must be shorted to enable the Bank 1 Analog Bus relays to
close. The optional 34922T terminal blocks short these pins
for you. This feature protects inadvertent routing of high
voltages from the Analog Buses to the D-sub connector of
the module.
