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-001 (for
2-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.
