Chapter 2 Install the Controller
See Physical Placement of I/O Modules on page 91 for requirements
related to Compact I/O local expansion modules.
For examples of Compact GuardLogix 5370 controller systems that use
one bank or multiple banks, see Mount the System
on page 27.
Assemble the System
You can attach an adjacent Compact I/O™ module or 1769 Compact I/O
power supply to Compact GuardLogix 5370 controllers before or after
mounting. For mounting instructions, see System Dimensions
on page 29 or
Mount the Controller on a Panel
on page 30.
Complete these steps to install the controller. This example describes how to
attach a 1769 Compact I/O power supply to the controller.
1. Verify that line power is disconnected.
2. Use your fingers or a small screwdriver
to push the bus lever of the 1769
Compact I/O power supply back
slightly to clear the positioning tab.
3. Move the bus lever to the right of the
positioning tab so it is in the unlocked
position.
ATTENTION: Compact GuardLogix 5370 controller systems do not
support removal and insertion under power (RIUP). These events
occur while the Compact GuardLogix 5370 controller system is under
power:
• Any break in the connection between the power supply and the
controller, for example, removing the power supply, controller, or an
I/O module, can subject the logic circuitry to transient conditions
above the normal design thresholds and can result in damage to
system components or unexpected behavior.
• Removing an end cap or an I/O module faults the controller and can
also result in damage to system components.
ATTENTION: Do not remove or replace this module while power is applied.
Interruption of the backplane can result in unintentional operation or
machine motion.
WARNING: Remove power before removing or inserting this module. If you
insert or remove the module while backplane power is on, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
