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 34925T-002 (for
1-wire) 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.
