HWAT Power Connection Kit with End Seal Installation Instructions
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 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.
• Bus wires will short if they contact each other. Keep bus
wires separated.
• Keep components and heating cable ends dry before
and during installation.
• The black heating cable core is conductive and can short.
It must be properly insulated and kept dry.
• Component approvals and performance are based
on the use of nVent–specified parts only. Do not use
substitute parts or vinyl electrical tape.
• Use fire-resistant insulation materials.
• Do not damage cable jackets or braid. Remove any
damaged cables or connections from service.
• Do not use aluminum feed wires.
• Leave these instructions with end user for reference and
future use.
HEALTH HAZARD: Overheating heat-shrinkable tubes will
produce fumes that may cause irritation. Use adequate
ventilation and avoid charring or burning. Consult MSDS
RAY3122 for further information.
