Replace the Line Fuse
Access the line power fuse from the rear panel. The fuse rating information above the ac
power input module shows the correct replacement fuse for each line voltage setting.
Table 7-1 shows the fuse part numbers for each line voltage setting.
To verify or replace the fuse, refer to Figure 7-1 and do the subsequent steps:
1. Disconnect line power.
2. The line power fuse and line voltage switch are in a compartment on the right end of
the ac input module. To open the compartment and remove the fuse, put the blade of
a standard screwdriver to the left of the tab at the left side of the compartment cover.
3. Pull the tab out of the slot and the compartment cover will come part way out.
4. Remove the compartment cover.
5. The fuse comes out with the compartment cover and can be easily replaced.
To install the fuse, push the compartment cover back into the compartment until the tab
locks with the ac input module.
