Install the I/O Module You can install or remove a module while chassis power is applied.Removal and
Insertion Under Power (RIUP) provides the flexibility to maintain modules
without having to stop production.
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 module and
its mating connector. Worn contacts may create electrical resistance that can affect
module operation.
ATTENTION: The module is designed to support Removal and Insertion Under
Power (RIUP). However, when you remove or insert an RTB with field-side
power applied, unintended machine motion or loss of process control can occur.
Exercise extreme caution when using this feature.
ATTENTION: Prevent Electrostatic Discharge
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.
