Description 1
Connection kit CKTES (Connection Kit Thermon Series Cable) is designed to connect a cold lead cable to a series
constant watt heating cable or to repair the Thermon Europe Series (TESH) constant watt heating cables.
The CKTES consists of a non-metallic enclosure which does not need to be earthed. Crimp connectors are used to
connect the braid and the conductor. They are separated by a non-metallic spacer. To make the CKTES watertight a
silicone sealant is used to ll the non-metallic body. This body is sealed off on both sides with a grommet and a non-
metallic screw cap.
After installation, the CKTES Termination and in-line splice kit shall be subjected to an insulation resistance test
according to EN 60079-30-2, clause 8.3.4, using a test voltage of 500 - 2500 Vdc in accordance with local regulations,
applied between the live conductors and the metallic braid of the power or heating cables. The measured insulation
resistance must be higher than 20 MΩ. For other cold lead cables, contact Thermon.
Important Remarks And Warnings
Before installing or replacing the product read these instructions completely.•
Thermon is unable to guarantee the performance of the joint when used in combination with non-Thermon •
products.
Installation must comply with local requirements for electric heat tracing systems. •
Water and dust ingress must be avoided before, during and after installation, to prevent electrical shock, short •
circuit or arcing.
Due to the risk of electric shock, short circuit, arcing and re caused by product damage or improper usage, •
installation or maintenance, Thermon heat tracing systems must always be installed in combination with an
overcurrent protection device and RCD (Residual Current Device).
Always take into account the markings on the CKTES concerning the temperature classication and explosion •
group.
Modications to the CKTES are not allowed. •
Before installation or replacement of the CKTES, ensure that the power supply to the system is switched off.•
For crimping lugs, use standard ratchet action crimping tool. Use crimp connectors matching the conductor •
diameter. Use crimping tools associated with the crimp connectors.
Avoid skin and eye contact with RTV sealant.•
When stored above 5°C, shelf life will be reduced.•
For Hazardous Areas:
Installation must comply with Thermon requirements and be installed in accordance with the regulation as per •
standard EN/IEC 60079-14 for hazardous areas (where applicable), and/or any other applicable national and local
codes.
This device is not suitable for zone 0. This device can be used in the following ATEX and IECEX zones: zone 1, •
zone 2, zone 21 and zone 22.
For power termination, use only ATEX/IECeX approved glands, terminals and junction boxes.•
Installation or replacement of the CKTES in hazardous areas may only be undertaken by qualied personnel with •
adequate training for the area involved.

Installation Instructions 4
Step 1
First determine the correct circuit length, then slide the screw cap and the
rubber grommet over the heating cable and cold lead cable (in case of a power
connection). Slide the housing over (one of) the heating cable(s).

Braiding
Remove 60 mm* outer jacket from both cables (*for TESH 600 up to TESH 8000, 75 mm). Separate braid strands at
the end of the outer jacket of the heating cable(s) and cold lead cable (PETK-10/11). Push back the braid away from
the heating cable to form a pigtail. Remove glass ceramic/polyamide tape. Pull the insulated conductor through the
opening in the braid of both cables.
Step 3
Twist the braid into a pig tail and trim the ends. Cut the braid of the Heating Cable at approximately 30 mm and 50 mm
for the Cold Lead / 2
and 45 mm).
nd
Heating cable. Cut the conductors at 50 mm* and 30 mm* (*for TESH 600 up to 8000, cut 65
Step 4
Remove primary insulation of the heating conductor and cold lead over a length of 15 mm (*in case of Cold lead or
TESH 2,9 and TESH 4,4 remove 20 mm, for TESH 600 up to 8000 remove 30 mm). **Side view of spacer in image.

Step 5
Insert the bare conductor of both the Cold Lead/Heating Cable and Heating Cable into the crimp connector and
ensure complete overlap of conductors inside the crimp connector. Crimp the crimp connector with matching crimping
tool. Follow the same procedure for terminating the braid of the Cold Lead/Heating Cable and Heating Cable. For
cable type TESH 600 up to TESH 8000, the heating cable conductor shall be folded double within the crimp*. For the
correct Crimp Connector type, see table page 3.
Step 6
Place the Spacer between both crimped connectors and ensure that both the leads and crimped connector are
properly placed inside the slots. Put a rich amount of silicone sealant on the crimped connectors and in the slots.
*Sealant on Crimp connectors.
Step 7
Slide the Housing over the assembled connections. Ensure assembled connection is positioned in the centre of the
Housing. Fill one end of the Housing with sealant ensuring that there are no air pockets and push the grommet into
the Housing. Ensure the joint and cable ends are held in position. Tighten the screw cap, repeat the operation at the
other end. Wipe off excessive sealant.
