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 34933T-002
(for 1-wire) terminal block shorts these pins for you. This safety feature
protects inadvertent routing of high voltages from the Analog Buses to the
D-sub connector of the module.
