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.
