Section 3: Shielded Wire Termination

3.1 Overview

This section shows the proper termination of the shield, if used.
Shielding of the SLC is recommended for use with IFC-200, IFC-300/400, JLIB-200. Proper
termination of the shield depends on the type of conduit used:
• Section 3.2, "No Conduit".
• Section 3.3, "Full Conduit" (Canadian requirement).
• Section 3.4, "Partial Conduit".
Shielding of the SLC is not recommended for use with IFC-320/E/C, IFC2-640/E, IFC-640/E,
IFC2-3030, IFC-3030, LCM-320, LEM-320, JLIB-200A or JLIB-400. If twisted-shielded wire is
used in one of these installations, use a floating shield to terminate the wire as shown in
Section 3.5, "Floating Shield", on page 25.
Use of good wiring practice consistent with local electrical codes is expected.

3.2 No Conduit

For use with IFC-200, IFC-300/400, and JLIB-200 only
Scrape the paint on the cabinet to bare metal to provide a good electrical connection. Fold the foil
and drain wire back over the cable jacket. Slide the cable into the connector clamp and secure. The
drain wire should be connected to the connector screw. Do not allow the shield drain wire or foil to
enter the system cabinet.
