Rockwell Automation 1771-OA AC (120V) Output Module - Manual (Page 10)

AC Output Module 10
Publication 1771-IN080A-EN-P - November 2002
The module has eight neon status indicators (Figure 3) that show the
state of each output. These indicators light when their corresponding
outputs are energized.
The module also has an indicator that displays a blown–fuse
condition at the respective output regardless of the state of the
output. This indicator is driven by your field device power supply.

Each module output is individually fused. You can easily access the
module fuses 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.
•
Failure to remove power from the backplane
could cause injury or equipment damage due to
possible unexpected operation.
If a blown fuse occurs:
1. Turn off power to the I/O chassis backplane.
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
side of the module by removing the two slotted screws.
4. Replace the blown fuse with a 2A, 250V Buss AGC2 fuse.
5. Replace the protective cover and install the module in the I/O
chassis.
6. Reposition the wiring arm.
7. Restart system power.
