ATTENTION
!
Remove power from the 1771 I/O chassis
backplane and field wiring arm before removing
or installing an I/O module.
• Failure to remove power from the backplane or
wiring arm could cause module damage, degra-
dation of performance, or injury.
• Failure to remove power from the backplane
could cause injury or equipment damage due to
possible unexpected operation.
1. Place the module in the plastic tracks on the top and bottom of the
slot that guides the module into position.
2. Do not force the module into its backplane connector. Apply firm
even pressure on the module until it is firmly seated in the
chassis. Note: The chassis locking bar will not close if all
modules are not seated properly.
