Prevent Electrostatic Discharge
Remove Power
System Assembly
The module can be attached to the controller or an adjacent I/O module before or after
mounting. For mounting instructions, see
Panel Mounting on page 8 , or DIN Rail Mounting on
page 9 . To work with a system that is already mounted, see Replacing a Single Module within a
System on page 9 .
The following procedure shows you how to assemble the Compact I/O system.
ATTENTION: This equipment is sensitive to electrostatic discharge, which can
cause internal damage and affect normal operation. Follow these guidelines when
you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.
WARNING: When 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.
Repeated electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance that can
affect module operation.
