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.
