nVent RAYCHEM E-40 End Seal Kit

Product Overview

The nVent RAYCHEM E-40 End Seal Kit is designed for terminating heating cables, specifically compatible with nVent RAYCHEM XTV, KTV, HTV, and VPL heating cables. It ensures a secure and safe end seal for electrical heat tracing systems.

Specific Conditions of Use

• Maximum Voltage: 480 Vac
• Maximum Exposure Temperature: 260°C (500°F)
• Minimum Installation Temperature: -60°C (-76°F)

Safety Warnings

• WARNING: To prevent electrical shock, short circuit, or arcing, this product must be installed correctly. Water ingress must be avoided before and during installation.
• Read all installation instructions completely before proceeding.
• Earth fault protection is required for each circuit.
• De-energize circuits before installation or servicing.
• Keep cable ends and kit components dry during installation.
• The electrically conductive covering (braid) of the trace heater must be connected to a suitable earthing terminal.
• The presence of trace heaters must be clearly indicated with caution signs or markings.
• Insulation resistance must be measured and recorded after installation, not less than 20 Megaohm.
• Personnel involved in installation and testing must be adequately trained.
• Installation must be supervised by a qualified person.
• A ground fault circuit interrupter (GFCI) is required.

Installation Steps Summary

The installation involves preparing the cable ends, applying heat shrink tubing, and ensuring proper connections. The following diagrams illustrate the process:

• Diagram 1: Shows the preparation of cable ends for XTV, KTV, HTV, VPL cables.
• Diagram 2: Illustrates cutting the cable end to a specified length (e.g., 30 mm / 1 1/4 in.).
• Diagram 3: Details preparing the cable end for XTV, KTV, HTV cables, showing specific measurements (10 mm / 1/2 in., 15 mm / 3/4 in., 5 mm / 1/4 in.).
• Diagram 4: Shows the preparation of cable ends for VPL cables, including measurements.
• Diagram 5: Depicts the crimping and sealing process for VPL cables.
• Diagram 6: Illustrates cutting the braid on VPL cables.
• Diagram 7A & 7B: Shows the application of heat shrink tubing to the cable ends.
• Diagram 8: Further illustrates the heat shrinking process.
• Diagram 9: Details the heat shrink technique using a heat gun, emphasizing optimal distance (5 mm) and movement to ensure even shrinkage without touching the cable or tubing. Recommended heat gun power is 3000 W or greater, with a temperature of 600-650°C.
