Product Usage Instructions: JBS-100-L-A Single Entry Power

Connection with Light and Junction Box

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.

Instructions

1. Identify the heating cable type and follow the corresponding installation steps for BTV-CR/BTV-CT/QTVR-CT, XTV-CT/KTV-CT, VPL-CT, or HTV-CT.
2. Unpack the JBS-100-L-A kit and ensure all components are included.
3. Follow the installation steps in the user manual to connect the heating cable to the JBS-100-L-A junction box using the provided components.
4. Plug in the JBL-100-R plug-in light module to indicate when power is supplied to the heating cable circuit.
5. Close the lid of the junction box.

Important Warnings

• Use nVent-specified parts only. Do not use substitute parts or vinyl electrical tape.
• 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.
• This component is an electrical device that must be installed correctly to ensure proper operation and to prevent shock or fire.

DESCRIPTION

The nVent RAYCHEM JBS-100-L-A is a Type 4X-rated power connection kit. 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 includes a plug-in LED light that indicates when the power is supplied to the heating cable circuit.
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.

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 JBS-SPA P/N E90515-000

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.
• 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 and flame-retardant foam.

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.

Heating cable types

• Allow approximately 24 in (60 cm) of heating cable for installation. For VPL, cut cable 12 in (30 cm) from bus indentation.

• Cut off heating cable end at about 45° for easier insertion.

• Optional: If stand is to be installed on bottom side of pipe, knock out drain hole prior to inserting cable.

• With label on stand facing desired direction of box opening, push 18 in (45 cm) of heating cable through stand. Use cable lubricant if needed.

• Square off cable end with 90° cut.

• Lightly score outer jacket around and down as shown.

• Bend heating cable to break jacket at score, then peel off jacket.

• Mark the jacket as shown.

• Push core sealer onto the heating cable to the mark made in step 6.
  Note: Extra force may be required for larger cables or at lower temperatures.

• Remove the guide tubes and dispose of them in a plastic bag.

• Slip the green/yellow tube onto the braid. Heat-shrinking is not required.

• Trim bus wires and braid.

• Pull heating cable back into stand so 1 in (25 mm) is exposed as shown. Use cable lubricant if needed.

• Fasten stand to pipe with label facing desired direction of box opening. Do not pinch heating cable.

• Loop and tape extra heating cable to pipe.

• 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
  • 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.

• Install conduit and fittings as shown. To minimize loosening due to pipe vibration, use a flexible conduit.

• Pull in power and ground wires, strip off 1/2 in (13 mm) of insulation, and terminate.

• Plug in the light module in the terminal blocks marked L and N as shown.
  (For simplicity the connected wires in the terminal blocks are not shown in this step.)

• Install lid.

• Apply insulation and cladding.

• Weather-seal the standing entry.

• Leave these instructions with the end user for future reference.

WARNING: Explosion Hazard- Substitution of Components May Impair Suitability for Class I Division 2 (Zone 2)
WARNING: Explosion Hazard- Do Not Disconnect Equipment Unless Power has been Switched Off or The Area is Known to be Non-Hazardous.
