How to Install Your Frequency Input Module
2. Make certain the flexbus connector (3) is pushed all the way to the
left to connect with the neighboring terminal base/adapter. You
cannot install the module unless the connector is fully extended.
3. Make sure that the pins on the bottom of the module are straight so
they will align properly with the connector in the terminal base unit.
4. Position the module (4) with its alignment bar (5) aligned with the
groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit.
The module is seated when the latching mechanism (7) is locked into
the module.
6. Repeat the above steps to install the next module in its terminal base
unit.

ATTENTION: Remove field-side power before removing
or inserting the module. This module is designed so you can
remove and insert it under backplane power. When you
remove or insert a module with field-side power applied, an
electrical arc may occur. An electrical arc can cause personal
injury or property damage by:
•
sending an erroneous signal to your system’s field
devices causing unintended machine motion
•
causing an explosion in a hazardous environment
Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating connector.
Worn contacts may create electrical resistance.
