• Crimp heating cable conductors together and use only the specified crimp
tool, die and splices to ensure a proper electrical connection (see table).
Improperly crimped connection can result in overheating.
• Smooth down any sharp wires after crimping to prevent wires from poking
through tape strips in Step 17.

WARNING: Fire and Health Hazard. Soldering tools or minitorches can cause fire or explosion
in hazardous areas. Be sure there are no flammable materials or vapors in the area before
using these tools. Follow all site safety guidelines when working in hazardous areas.
Refer to solder material safety data sheet packaged with kit.
Do not overheat or char the conductor insulation. Inhalation of fumes can cause polymer
fume fever, flu-like symptoms, irritation, and difficulty breathing.
Do not direct torch flame toward conductor insulation, cold lead insulation, or enclosure.
Damage to insulation or enclosure can lead to shorting or moisture ingress.
• Use only solder provided with the kit. Only Kester 48 core LF has been qualified for use with
SC cables.
• Heat each splice using a soldering tool, or propane or MAPP gas torch. Note: MAPP gas may
be required if the connections are being soldered at temperatures below –4°F (–20°C). Heat
the center of the splice until it is hot enough to melt the solder placed at both ends. Allow
the splices to cool for several minutes before proceeding to the next step of wrapping the
connection with tape.
