It is designed for use with nVent RAYCHEM BTV-CR, BTV-CT, QTVR-CT, XTV-CT, KTV-CT, HTV-CT and VPL-CT industrial parallel heating cables. The kit can be used to connect one, two, or three heating cables to power, to connect two separate heat-trace circuits, or to splice or tee up to three heating cables. The kit includes a plug-in light module that indicates when power is supplied to the heating cable circuit. Note: For two or more heating cables powered by a single circuit, the length of each heating cable should not exceed the maximum allowable circuit length published in the nVent RAYCHEM self-regulating cables design guide and the total current of all heating cables on the circuit should equal no more than 80% of the circuit breaker current rating. 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 nVent at (800) 545-6258. TOOLS REQUIRED · Wire cutters · Adjustable pliers · Needle nose pliers · Utility knife · 1/4 in or smaller slotted screwdriver · Marking pen · Wire stripper(for VPL-CT) · Large slotted screwdriver · 3/8 in hex key (required for splice and tee connections) ADDITIONAL MATERIALS REQUIRED · Pipe strap · GT-66 or GS-54 glass cloth tape OPTIONAL MATERIALS · Recommended conduit drain: JB-DRAIN-PLUG-3/4IN P/N 278621-000 · Small pipe adapter for 1 in (25 mm) and smaller pipes: Catalog number JBM-SPA P/N D55673-000 A B K C J D I E H F G nVent.com/RAYCHEM | 1 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 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. AVERTISSEMENT : Ce composant électrique doit être installé correctement pour éviter les risques d'incendie ou de chocs électriques. Lire ces avertissements importants et suivre attentivement toutes les instructions d'installation. · Pour réduire le danger d'incendie causé par un arc électrique entretenu, si le câble chauffant est endommagé ou mal installé, et pour respecter les exigences de nVent et celles des codes applicables, il est impératif d'utiliser une protection par disjoncteur différentiel. Les disjoncteurs ordinaires ne sont pas toujours capables de supprimer les arcs électriques. · Les approbations et les performances des composants sont basées sur l'utilisation des pièces nVent spécifiées seulement. N'utilisez pas de pièces de rechange ou de ruban isolant en vinyle. · 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. · Le noyau et les fibres du câble chauffant noir sont conducteurs et peuvent provoquer un court-circuit. Ils doivent être correctement isolés et gardés à sec. · Les fils omnibus endommagés peuvent surchauffer ou subir un court-circuit. · Ne brisez jamais les fils omnibus lorsque vous incisez la gaine ou le noyau. · Maintenez les composants et les extrémités des câbles chauffants secs avant et pendant l'installation. · Les fils omnibus peuvent provoquer un court-circuit s'ils se touchent. Les garder à l'écart les uns des autres · N'utilisez que des matériaux isolants ininflammables, par exemple une gaine de fibre de verre ou de la mousse ignifuge. · Laissez ces instructions d'installation à l'utilisateur pour qu'il puisse les consulter. CAUTION: 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.

Terminals use a steel spring to clamp the wire to provide improved vibration resistance, reduced maintenance and faster installation. To connect wires, firmly insert a slotted screwdriver into the square hole ( 1 ) to open the spring. When fully inserted, the screwdriver will lock into place, allowing you to remove your hand and insert the wire into the round hole ( 2 ). Remove the screwdriver to clamp the wire. The wire is held securely against the bus bar for low contact resistance over time without the need to periodically retighten screws. 1 2 Wire · Refer to wiring diagram, step 18A, 18B, or 18C. · Push screwdriver FIRMLY into square hole. · Insert wire into round hole. · Use green terminal for braid and ground wires. · Remove screwdriver. · Repeat for all connections.
