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 34923T-002 (for
1-wire) 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.
