Replacing a Distribution Device
General
Replace distribution devices with the same type and rating, or equivalent. Refer to SAG584622100 (System Application Guide) for
part numbers.
Distribution Fuse “Alarm Fuse” Replacement
If a distribution fuse opens, the associated alarm fuse opens. Replace the distribution fuse before replacing the alarm fuse.
Procedure
1.
An alarm fuse is removed by pulling it straight out of the fuseholder. If the alarm fuse is located in a modular fuse carrier, hold
the fuse carrier in place with your thumb while pulling on the alarm fuse to prevent the entire carrier from inadvertently being
pulled out.
2.
Safety fuse covers are provided for all Bussmann GMT type fuses installed in the system. These covers snap onto the fuses
and provide protection from exposed electrical terminations when a fuse opens. Ensure that the safety fuse cover is installed
after replacing a fuse. Refer to Figure 8.1 for installation details.
