WARNING::
As a safety
feature, interlock 1 pins
(17 and 33) on Bank 1
must be shorted to enable
the Bank 1 Analog Bus
relays to close. The
optional 34921T terminal
block shorts these pins for
you. This feature protects
inadvertent routing of
high voltages from the
Analog Bus to the D-sub
connector of the module.
