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 34931T 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.
