Approximately 8 inches (20 cm) of horizontal wall space is required for each
column of sneak fuse panels. Connector cables connect the network interface to
the sneak fuse panel. Also, use 157B connecting blocks equipped with SCP-110
protectors for sneak current protection.
NOTE:
Sneak current protectors with a rating of 350 mA at 600 Volts must be UL
listed for United States installations and CSA certified for Canadian
installations. The panel contains two 25-pair connectors, fuse removal tool,
and fifty 220029 Sneak Fuses (and 2 spares). Use the SCP-110 protectors
with 110-type hardware and on the 507B Sneak Fuse Panel. The SCP-110
Protectors can be ordered separately and installed on the 157B connecting
block. Fifty protectors are required per block.
1. Install the 507B near the network interface or MDF with locally-obtained
#12 x 3/4-inch screws (or equivalent).
