as this procedure is performed.
1. Open the Distribution Cabinet's front door by turning and holding the captive fastener in the
counterclockwise position.
2. Remove the fuse carrier from the mounted fuseholder body by pulling it straight out.
3. Gently rock the defective fuse holder up and down while pulling firmly outward until the fuse holder is
free from the distribution assembly.
WARNING! If the following procedure is not followed, the fuseholder may be damaged.
4. Orient the fuseholder so the LOAD designation found on the fuseholder side is at the top, and the LINE
designation is at the bottom. Insert the terminals on the rear of the fuseholder into their corresponding
sockets on the distribution assembly. Push fuseholder in firmly until fully seated.
5. Push the fuse carrier back into the fuseholder body. Note that a polarizing key on the bottom of the
carrier prevents the carrier from being inserted upside down.
6. Verify no Fuse Alarms are active.
7. Close the Distribution Cabinet's front door. The door can be shut without turning the captive fasteners.
