As a safety feature, interlock 2 pins (39 and 59) on Bank 2 must be
WA R N I N G
shorted to enable the Bank 2 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.
