Step 1

The cable is to be prepared as shown in Fig. 1. For L1 dimension see table. Choose measurement L2 depending on the installation. The inner cable jacket (A2) must be free of damage and should extend beyond the cable gland.

Important: The Exios Barrier Cable Gland is typically designed for use with armored cables. However it is also possible and permitted to use with NON-ARMORED cables. In this case it is important to use one clamping ring as a spacer for the installation!

Step 2

The cable gland is delivered with 2 armor clamping rings. Choose the appropriate clamping ring (measure armor thickness and see Table 1); the other ring can be discarded. Follow the installation instructions shown in Fig. 2. Pay attention to the correct installation of the clamping ring, Fig. 3. The arrow on the clamping ring should point towards the installation.

Step 3

Install the entry component on the device or housing (∼15Nm / 11.6 foot pounds). The end-user is responsible for ensuring that, at the point of installation, the adapter for the entry component has been made ready in accordance with Regulations. The entry component can be provided with a locknut to keep it from working loose.

Step 4

Position the armour of the cable so that all parts of the armor are in contact with the armor cone (Fig. 4) and the ends of the armor touch the edge of the armor cone. Now screw the gland body hand-tight onto the entry component. It helps if, while doing so the cable is pushed slightly in towards the device or housing. With the appropriate open-ended spanner (tool), tighten fast in order to securely clamp the armor.

Step 5

Loosen the gland body and check for correct seating of the armor (Fig. 5). The armor must be firmly clamped. If need be, repeat step 4.

Preparing the Compound: Please check the compound expiration date. Read the attached Safety Data sheet. Use the protective gloves included, as well as suitable eye protection. The compound can be applied at temperatures between +10C and + 40C. Application is ideally carried out at room temperature (+20C). Processing time is approx. 15 min. Please see Table 2 for Cure Time of the Compound.

Step 6

Mix and knead the appropriate quantity of compound for the job until a completely uniform color is achieved. As shown in Fig. 6, apply the compound between and around the individual conductors. To prepare for the sleeve (cover) it is easy if the compound has first been giving a conical shape as in Fig. 7. To stop the conductors moving out of place, they can be held together with scotch tape.

Step 7

Push sleeve over compound portion behind armor cone. This causes the compound to be compressed. Remove the excess compound. Care should be taken that sleeve has been filled right up to the end. The outside of the sleeve is to be kept clean.

Step 8

The cable can now be inserted into the entry component. The sleeve should be inserted carefully.

Step 9

After the entry component and the gland body have been screwed together again (Step 4, Nm), the dome nut can now be tightened. To speed up assembly, it can be tightened by hand to start with. Then tighten down using an open-ended spanner (Nm).

General information:

Our metric-size cable glands are provided as standard with an O-ring on the connecting thread.
Before initial operation of the facilities, the assembly is to be checked to see that it conforms to these installation instructions, to the applicable national and international standards, as well as those applicable to the use in question.
Suitable tools must be used for the assembly; furthermore, the installation may only be carried out by qualified electricians or by trained staff.
Any modification which differs from the condition as delivered is not permitted.
In order to fulfill explosion protection type Ex-d, the cable used must be round and compact (cf. IEC 60079-14 Para. 10.2). The cables must also take into consideration in particular the Regulations as per EN 60079-14 Section 9.5.2. Observe the Regulations of EN 60079-14 on direct insertion into the Ex-d area.
At the specified maintenance intervals it is recommended to check the compression fittings and tighten as necessary.
The use of cables without armor or alternatively the use of cables with shielding braid is only permitted for permanently installed power lines (25%).
In the case of NPT connecting threads, the end-user must ensure that the necessary IP protection is guaranteed; this can be done using a suitable thread sealing agent.
When installing the cable gland through bore holes, care should be taken that the maximum diameters are not exceeded.
The cable glands are provided with a sealing ring with an axial sealing height of at least 5 mm. With reference to the clearance groove, the end-user should ensure that at least five complete turns of the connector thread are made. In order to guarantee a screw depth of 8 mm, the enclosure should have a wall thickness of min. 10 mm ; if <10 mm, then if necessary, use a washer when cable entries are attached to the pressure-resistant enclosure.
When determining the temperature ranges of the device in the dust Ex-area, the Regulations of EN 60079-0 and EN 60079-31 must be taken into consideration.
