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 nVent, agency certifications, and
national electrical codes, ground-fault equipment
protection must be used. Arcing may not be
stopped by conventional circuit breakers.
•The power connection may be powered by more
than one circuit. Be sure all power sources are
de-energized before opening box.
•Component approvals and performance are
based on the use of nVent specified parts only.
Do not use substitute parts or vinyl electrical
tape.
•The black heating cable core and fibers are
conductive and can short. They must be properly
insulated and kept dry.
•Damaged bus wires can overheat or short. Do
not break bus wire strands when scoring the
jacket or core.
•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.
HEALTH HAZARD: Prolonged or repeated contact
with the sealant in the core sealer may cause skin
irritation. Wash hands thoroughly. Overheating or
burning the sealant will produce fumes that may
cause polymer fume fever. Avoid contamination of
cigarettes or tobacco. Consult MSDS VEN 0058 for
further information.
