ATTENTION
Remove power from the 1771 I/O chassis
backplane before you install the module. Failure
to remove power from the backplane could cause:
•
module damage
•
degradation of performance
•
injury or equipment damage due to possible
unexpected operation
!
WARNING
When you insert or remove the module with field
power applied, or connect or disconnect the field
wiring arm with field side power applied, 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.
Place the module in the card guides on the top and bottom of the chassis
that guide the module into position.
Important: Apply firm even pressure on the module to seat it into its
