Bank 2
WARNING
As a safety feature, interlock 1 pins (39 and 59) on Bank 1 must be shorted to
enable the Bank 1 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.
For orientation, the D-sub connector
end of the module is facing you.
