Safety instructions

Heating cables must always be installed according to local
building regulations and wiring rules as well as the guide-
lines in this installation manual.
• De-energize all power circuits before installation and service.
• Residual current device (RCD) protection is required. RCD trip
rating is max. 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 according to local regulations.
• Never exceed the maximum heat density (W/m or W/m²)
for the actual application.
3 Installation guidelines
• It is not recommended to install heating cables at tem-
peratures below -5°C.
• Heating cable bending diameter must be at least 6 times
the cable diameter. Do not bend connections.
