WARNING

As a safety feature, interlock pins (17 and 33) must be shorted to enable the
Analog Bus relays, which are on Matrix 2, to close. The optional 34932T
terminal block shorts these pins for you. This feature protects inadvertent
routing of high voltages from the Analog Buses to the D-sub connector of
the module.
