Rockwell Automation 1771-OMD AC(220V) Output Mod Installation Instructions - Manual (Page 8)

8 AC (220V) Output Module Cat. No. 1771-OMD Series B
Publication 1771Ć5.26 - February 2000
The module’s output circuitry is protected from overload or shorts by
a fuse. You can replace the fuse as outlined below.
1. Turn off all power to the I/O chassis and all output device power
to the field wiring arm.
!
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.
2. Pivot the wiring arm away from the module and remove the
module from the chassis.
3. Replace the blown fuse with a 10A, 250V rectifier fuse (1/4 x
1-1/4 inch), Littelfuse part number 322010.
4. Replace the module in the chassis and attach the field wiring arm.
If a problem occurs, follow the procedure below.
