As a safety feature, interlock 1 pins (39 and 59) on Bank 1 must
WA R N I N G
be shorted to enable the Bank 1 Analog Bus relays to close. The
optional 34924T 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.
