INSTRUCTIONS FOR SAFE USE
Klippon ® KDSU Cable Glands
0344
Brief Description
The KDSU type cable gland is for outdoor use in the appropriate Hazardous Areas with armoured, un-armoured, braided and screened cable.
It gives environmental protection to IP66, IP68 and Deluge. A variant giving electrical continuity to a lead sheath is available. A termination suitable for
EMC protection can be made using armoured cables with this gland.
Warning
PLEASE STUDY CAREFULLY BOTH PAGES OF THESE INSTRUCTIONS BEFORE INSTALLATION. These glands should not be used in any
application other than those mentioned here or in our Data Sheets, unless Weidmuller states in writing that the product is suitable for such application.
Weidmuller can take no responsibility for any damage, injury or other consequential loss caused where the glands are not installed or used according to
these instructions. This leaflet is not intended to offer advice on the selection of cable glands. Further guidance can be found in the standards listed
overleaf.

Split gland as shown
Fit Entry Body to enclosure including sealing washer if required. Hand-tighten, then suitably secure with a wrench.
Slide Rear Assembly (and shroud if required) onto cable as shown.
Prepare Cable
A Strip outer jacket and armour length to suit installation. On options for lead sheathed cable the lead sheath must pass
through the Continuity Washer when installation is complete (the Continuity Washer is fitted under the Compression Nut)
B Expose armour. For approximate lengths see Table 1 column B. Where sheath sizes are near minimum, form armour to
facilitate clamping as shown.
Slide the Clamp over the exposed armour. Ensure the Clamp is in the correct orientation.
Slide Cone onto inner sheath and under armour. Slide Clamp onto exposed armour
For lead sheathed cable - Unscrew the Compression Nut, remove the Continuity Washer and replace the Nut.
For all cables Insert cable through Entry Body. Push cable forward to maintain armour contact.
To clamp armour/braid onto Cone, hand-tighten Mid Cap to Entry Body. For cable with maximum diameter wire armour it
may be necessary to remove the internal skid washer (located under nut) first. Support the cable to prevent it from twisting
then using wrench tighten a further 1 turn. Cable with maximum diameter wire armour may require an additional ½ to 1 turn.
Loosen off Mid Cap to visually check armour is securely locked. If armour has not clamped repeat the clamping process.
For lead sheathed cable - Replace Continuity Washer and Nut. Reinsert cable.
For all cables (If removed replace internal skid washer) Tighten Compression Nut so that seal makes full contact with cable
sheath and then tighten the Compression Nut by the additional turns detailed in Table 2.
Re-tighten Mid Cap by hand until tight. For cable with wire armour turn Mid Cap a further 1 turn with a wrench.
For cable with all other armour types turn Mid Cap a further ¼ turn with a wrench after hand tight.
Hold Mid Cap with wrench and tighten the Back Nut onto cable. Ensure the seal makes full contact with cable outer sheath
and then tighten the back nut by the additional turns detailed in Table 2. If fitted, pull shroud over gland assembly.

Advice
♦ EN/IEC 60079-10 Classification of Hazardous Areas
♦ EN/IEC 60079-14 Electrical Installations in Hazardous Areas
♦ EN/IEC 60079-31 Ignitable dust – Protection by enclosure
♦ BS 6121, Part 5 Selection, Installation & Maintenance of Cable Glands
Installation should only be carried out by a competent electrician, skilled in cable gland installation.
NO INSTALLATION SHOULD BE CARRIED OUT UNDER LIVE CONDITIONS.
Threaded entries: the product can be installed directly into threaded entries. Threaded entries should comply with clause 5.3 of IEC/EN
60079-1 and have a lead-in chamfer to allow for full engagement of the threads. For Ex d applications a minimum of 5 fully engaged parallel
threads is required. Metric threads are supplied with an o-ring and will maintain IP66 and IP68. Parallel entry threads will maintain an IP
rating of IP64. A sealing washer should be used to maintain all IP ratings greater than IP64.
Clearance holes: these may be 0.1 to 0.7mm larger than the major diameter of the male thread. The product should be secured with a lock nut and
the threads tightened to ensure the cable gland is secure. A sealing washer should be used to maintain IP ratings. A serrated washer should be
used for additional installation protection.
To maintain the Ingress Protection rating of the product, the entry hole must be perpendicular to the surface of the enclosure. The surface should
be sufficiently flat and rigid to make the IP joint. The surface must be clean and dry. It is the users/installers responsibility to ensure that the
interface between the enclosure and cable gland is suitably sealed for the required application.
Whilst Weidmuller products with tapered threads, when installed into a threaded entry, have been tested to maintain IP66 without any additional
sealant, due to the differing gauging tolerances associated with the use of tapered threads it is recommended to use a non-hardening thread sealant
if an IP rating higher than IP64 is required.
Once installed do not dismantle except for routine inspection. An inspection should be conducted as per IEC/EN 60079-17. After inspection the
gland should be re-assembled as instructed, ensuring the mid cap and back nut are correctly tightened to ensure the cable is secure.
For Ex d applications, these glands should only be used with substantially round and compact cables with extruded bedding (i.e. effectively filled
cables) that are compliant with EN/IEC 60079-14.
If used in a non-metallic increased safety enclosure, the gland must be included within in the earth circuit of the system.

Special Conditions for Safe Use
1. These glands must not be used in enclosures where the temperature at the point of mounting is outside the range of -35°C to +90°C using neoprene
seals, or –60° to +180°C using silicone seals.
2. When the gland is used with increased safety and/or dust protected equipment, the entry thread shall be suitable sealed to maintain the ingress
protection rating of the associated enclosure.
3. If these cable glands only grip the cable sheath of the cable and do not clamp the cable armour or if they are used to terminate unarmoured, braided
or screened cables, then they shall only be used for fixed installations, hence the cables shall be effectively clamped to prevent pulling or twisting.
4. These glands, when installed in accordance with the manufacturers instructions and with an appropriate enclosure on which they are fixed, are
capable of providing an ingress protection of IP66 and IP68 (50 metres 7 days)
5. Where glands without sealing rings are installed in protection by enclosure (Ex t) equipment for use in explosive dust atmospheres, they may only be
fitted into enclosures offering a minimum of 5 full threads, in accordance with EN 60079-31:2009 clause 5.1.1.
