overload or a shorted output triac condition. You can easily access
the module fuse by removing the front component–side cover.
ATTENTION
!
Remove power from the 1771 I/O chassis
backplane and wiring arm before removing or
installing the module.
•
Failure to remove power from the backplane or
field wiring arm could cause module damage,
degradation of performance, or injury.

could cause injury or equipment damage due to
possible unexpected operation.

2. Pivot the wiring arm away from the module and pull the module
from the I/O chassis.
3. Remove the front half of the protective cover from the unlabeled
