Installing sneak fuse panels
For general information, see Installing sneak current and off premise protection on page 54.
Figure 26: Model 507B sneak fuse panel on page 55, or equivalent, is recommended for sneak current protection. The panel contains two 25-pair connectors, fuse removal tool, and fifty 220029 sneak fuses (and two spares). See Table 6: Sneak fuse connector pinout on page 56 for pinout data.
To install sneak fuse panels:
1.Locate the 507B near the network interface or the main distribution frame (MDF).
2.Hold the panel against the mounting surface and mark the mounting screw locations. Drill pilot holes at the marked locations and partially install a locally obtained #12 x 3/4-inch screw into the two bottom mounting slots.
3.Slide the sneak fuse panel onto the mounting screws and tighten the screws securely.
4.Install a locally obtained #12 x 3/4-inch screw into the top two mounting slots and tighten securely.
5.Repeat the procedure for each sneak fuse panel.
6.Secure the B25A cable to the panel with the captive screw on the connector and a supplied cable tie.
