The output of this module is fused to open the output circuit under an

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.

• 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 5A, 250V Bussman MTH5, IEC

127 Type F fuse.

5. Replace the protective cover and install the module in the I/O

chassis.

6. Reposition the wiring arm.

7. Restart system power.
