1 Overview
Danfoss Connecto NA is a family of connection kits for self-regulating heating cables (trace heaters).
The Connecto NA connection kits are simple and safe to use, yet faster to install and more cost effective
than conventional systems. They can be used with Danfoss PX/RX heating cables in fixed equipment
heating systems for multiple applications (e.g. heating of pipes, roof and gutter de-icing etc.).

Installation Instruction
Danfoss Connecto NA connection kits
• For roof and gutter applications use only the UV-resistant Danfoss RX-C ‘black’ heating cable (certified by the –WS mark on the device).
• Any defective component in a set must be replaced before installation.
• Keep all components and the heating cables dry before and during installation.
• To avoid short circuits, do not connect the heating cable bus wires together.
• When used for roof and gutter de-icing, the Connecto NA connection kit must be installed in a dry
place outside the gutter.
• For end seal installation silicone adhesive is used. Follow the safety instructions given on the packaging.
• Keep these instructions for future reference. If applicable, leave them with the end user.
• De-energize before installation or servicing.
• Use only original Danfoss accessories.

8 Attachment to pipes
Attachment methods.
NOTICE:
It is recommended to install the Danfoss Connecto NA connection kit connection kit on a mounting
bracket (“off-pipe”) to protect it from excessive temperatures (as shown on the left). However, when
used in moderate temperature conditions all Danfoss Connecto NA connection kits can also be
directly attached to the pipe (as shown in 1B).
Off-pipe installation:
• Attach the mounting bracket (see section Accessories on page 10) to the pipe using cable ties.
• Attach the Danfoss Connecto NA connection kit to the mounting bracket and the trace heater to
the pipe using polyester tape or cable ties.
• Make sure that the distance between 2 attachment points does not exceed 12" (300 mm) on plastic
pipes or 36" (900 mm) on steel pipes.
