ATTENTION
Do not remove the CompactFlash card while the controller is reading from or
writing to the card, as indicated by a flashing green CF status indicator. This
could corrupt the data on the card or in the controller, as well as corrupt the
latest firmware in the controller.
WARNING
When you insert or remove the CompactFlash Card while 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.
