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.
Wiring to the analog modules is made through the terminal base unit
on which the module mounts.
Refer to the following table for recommended terminal base units
that you can use for each module.
