Installation Guide for Danfoss Heating Cables

Quick guide from the manual

This document provides installation instructions for various Danfoss heating cables. It covers safety requirements, installation guidelines, mechanical classifications, and warranty terms. Always consult local building regulations and wiring rules before installation.

Safety instructions

• De-energize all power circuits before installation and service.
• Residual current device (RCD) protection is required with a max trip rating of 30 mA.
• The screen from each heating cable must be earthed in accordance with local electricity regulations.
• Heating cables must be connected via a switch providing all-pole disconnection.
• The heating cable must be equipped with a correctly sized fuse or circuit breaker.
• It is strongly recommended to use the heating cable with an appropriate thermostat to prevent overheating.
• Do not use M1 classified cables in areas subject to high mechanical loads or impact (e.g., outdoor applications, steel reinforcing grids, concrete with sharp stones, roofs, and gutters).
• The presence of a heating cable must be clearly marked in the fuse box, distribution board, and along the circuit line.

Installation guidelines

• Do not install heating cables at temperatures below -5°C.
• The bending diameter of the heating cable must be at least 6 times the cable diameter.
• Do not bend the connections.
• The free end of the cold lead must be protected by the installer to prevent water ingress.

Mechanical classes

M1: For applications with low risk of mechanical damage (e.g., installed on even surfaces and embedded in screeds without sharp objects).

M2: For applications with high risk of mechanical damage.

C: High mechanical strength according to IEC 60800:1992.

MMM: Marking for high mechanical protection class according to NF C 32-330:2002.

Warranty information

Danfoss offers various warranty periods (5, 10, or 20 years) depending on the product type. The warranty covers repair or replacement costs and, for full-service products, installation and floor material damage. The warranty is valid only if the Warranty Certificate is correctly filled out, stamped, and signed by an authorized installer. Keep the certificate and proof of purchase for the entire warranty period.

Application overview

The manual includes a detailed application table (page 6) that specifies which cable type is suitable for various applications, such as pipe tracing, concrete embedding, roof and gutter heating, and asphalt applications.
