DESCRIPTION
The nVent RAYCHEM JBM-100-L-A is a Type 4X-rated connection kit. It is
designed for use with 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.

HEATING CABLE TYPES
• Determine heating cable type
and continue as shown.
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.
• 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.
Danger pour la santé: Le contact prolongé ou répété avec le
produit d'étanchéité du noyau peut provoquer une irritation de
la peau. Lavez-vous les mains soigneusement. La surchauffe
et la combustion du produit d'étanchéité produira des vapeurs
qui peuvent causer la fièvre des vapeurs de polymères. Évitez
la contamination des cigarettes ou du tabac. Consultez la
fiche technique santé-sécurité (FTSS) VEN 0058 pour obtenir
de plus amples informations.

AVERTISSEMENT:
MISE EN GARDE:
CAUTION:
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.

Screwdriver slot
Wire hole

This kit uses spring clamp style terminals.
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 (

) 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 (
1

). 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.
• 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.
