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.
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.
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.
