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 34923T-002 (for
1-wire) 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.
