34925A D-Sub Connectors for Two- or Four-Wire Mode

Bank 1
WARNING 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.
Bank 2
WARNING:: As a safety
WARNING
feature, interlock 2 pins
(17 and 33) on Bank 2
must be shorted to enable
the Bank 2 Analog Bus
relays to close. The
optional 34925T-001 (for
2-wire) terminal block
shorts these pins for you.
This feature protects
