2SC-LSC
Splice Connection Kit Installation Instructions
Description
The 2SC-LSC is a NEMA 4 rated splice connection kit for use with
Raychem 2SC60, 70, 80 (-CT), 2SC/H60, 70, 80 (-CT) and 2SC/F60, 70,
80 (-CR) series heating cables in ­hazardous locations.
This kit may be installed at temperatures as low as –40°F (–40°C).
For easier installation, store above freezing until just before
installation.
For technical support, call Pentair Thermal Management at
(800) 545-6258.

WARNING:
This component is an electrical device that must be installed
correctly to ensure proper operation and to ­prevent shock or fire.
Read these important warnings and carefully follow all of the
installation instructions.
• To minimize the danger of fire from sustained electrical arcing
if the heating cable is damaged or improperly installed, and to
comply with the requirements of Pentair Thermal Management,
agency certifications, and national electrical codes, groundfault equipment protection must be used. Arcing may not be
stopped by conventional ­circuit breakers.
• Component approvals and performance are based on the use of
Pentair Thermal Management-specified parts only. Do not use
substitute parts or vinyl electrical tape.
THERMAL MANAGEMENT SOLUTIONS
CAUTION:
• Damaged conductors can overheat or short. Do not break
conductor wire strands when scoring the jacket or removing
insulation.
• Keep components and heating cable ends dry before and during
installation.
• Use only fire-resistant insulation materials, such as fiberglass
wrap or flame-retardant foam.
• Soldering tools or torches can cause fire or explosion in
hazardous areas. Be sure there are no flammable materials or
vapors in the area before using these tools.
• Wrap exposed conductors with supplied tape strips to prevent
shorts.

Health Hazard: Hot solder can burn eyes and skin. Fumes
during soldering are irritating to eyes and may cause headache
and respiratory system irritation or damage. Prolonged or repeated
exposure to rosin flux fumes during soldering may result in allergic
reaction in a sensitive person, resulting in asthma symptoms.
Consult MSDS VEN0043 for further information.
Silicone rubber compound Part B, may ­generate flammable and
explosive hydrogen gas if it comes in contact with an acidic, basic
or oxidizing ­material. Personal contact with the silicone rubber
­compound may cause slight eye or skin irritation. Consult MSDS
VEN0030 and VEN0031 for further information.

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 difficult breathing.
• Useonlysolderprovidedwithkit.OnlyKester48coreLFhasbeenqualified

enough to melt the solder placed at both ends.
Allow the connection to cool before proceeding to the next step.
