Protecting the Circuit Board from Contamination
The printed circuit boards of the analog modules must be protected
from dirt, oil, moisture, and other airborne contaminants. To protect
these boards, the system must be installed in an enclosure suitable for
the environment. The interior of the enclosure should be kept clean
and the enclosure door should be kept closed whenever possible.
System Assembly The module can be attached to the controller or an adjacent I/O
module or power supply before or after mounting. For mounting
instructions, see Panel Mounting Using the Dimensional Template on
page 3-7, or DIN Rail Mounting on page 3-8. To work with a system
that is already mounted, see Replacing a Single Module within a
System on page 3-9.
The following procedure shows you how to assemble the Compact
I/O system.
1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the
unlocked (fully right) position.
3. Use the upper and lower tongue-and-groove slots (A) to secure
the modules together (or to a controller or power supply).
4. Move the module back along the tongue-and-groove slots until
the bus connectors (B) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (C).
Use your fingers or a small screwdriver.
