Explosion Hazards
Preventing Electrostatic Discharge
Removing Module While Under Power (RIUP)
WARNING
An electrical arc can occur if you:
• insert or remove the CompactFlash card.
• insert or remove the controller while backplane power is on.
• connect or disconnect the battery.
• connect or disconnect the serial cable with power applied to this module
or the serial device on the other end of the cable.
This could cause an explosion in hazardous location installations. Make sure
that power is removed or the area is nonhazardous before proceeding
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.
