Instructions for installation of Ex cable glands
PLEASE STUDY CAREFULLY ALL 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 Peppers states in writing that the product is suitable for such application. Peppers 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 advice on the selection of cable glands.

STEP-BY-STEP FITTING INSTRUCTIONS (NOTE: No Back Nut in D1W gland)
1. Split gland as shown. Remove Seal to reduce cable damage. E2 types:- remove Continuity
Washer. E9 types:- remove Deluge Seal.
2. Check Clamp:- FOR KITS E1L/D1L/E9L ETC:- Use PLAIN clamp ring for wire armour. Use GROOVED clamp ring IN BAG for woven wire or tape armour.
3. Fit Entry Body. For correct torque see page 2. DO NOT EXCEED MAX TORQUE FOR ENCLOSURE.
Slide Rear Assembly including Clamp onto cable as shown.
4. Prepare cable as shown in diagram.
A Strip outer jacket andarmour, length to suit installation. For lead sheathed cable the lead sheath must pass through the Continuity Washer when installation is complete.
B Expose armour approx. 20mm long.
5. Slide Cone onto inner sheath and under armour. Slide Clamp onto exposed armour.
Insert cable through Entry Body. DO NOT RE-FIT SEAL OR CONTINUITY WASHER.
6. Tighten Mid Cap to Entry Body to make-off armour. FOR CORRECT TORQUE SEE PAGE 2.
7. Loosen off Mid Cap to visually check armour is securely locked. Pull out cable from Entry Body.
8. RE-FIT SEAL (AND CONTINUITY WASHER ON E2 TYPES) (AND DELUGE SEAL ON E9
TYPES).
9. Re-insert cable through Continuity Washer, Seal and Entry Body. For lead sheathed cable the Continuity Washer must be in contact with the lead sheath and must be in front of the seal.
10. Re-tighten Mid Cap to correct torque.
11. Hold Mid Cap with wrench and tighten Back Nut onto cable.
12. Ensure Seal makes full contact with cable sheath, then tighten Back Nut 1 extra turn

6121, Part 5 Selection, Installation and Maintenance of Cable Glands
2
Installation should only be carried out by a competent electrician, skilled in cable gland installation.
3
NO INSTALLATION SHOULD BE CARRIED OUT UNDER LIVE CONDITIONS.
4
To maintain Ingress Protection ratings above IP54, use IP washers or O-rings for parallel threads. For taper threads use thread sealant. Also see
page 1 diagram and Hole Data above.
5
The surface of the enclosure should be sufficiently flat and rigid to make both the IP joint, and earth contact where needed. With painted
enclosures, a star washer should be fitted to break through the paint and make a satisfactory earth contact.
6
Once installed do not dismantle except for occasional inspection. If necessary, dismantle by reversing the Fitting Instructions given above. The gland is not serviceable and spare parts are not supplied.
7
Parts are not interchangeable with any other design. If manufacturers' parts are mixed, certification will be invalidated.
Limitations on Usage. Be sure your installation complies with the following:

Comment
Enclosure entry
thread
The female thread in the enclosure must comply with clause 5.3 of EN 50018, or clause 5.3 of IEC 79-1, as appropriate. Do not damage threads on assembly. Check the number of full turns of thread engaged is at least 5.

Cable glands are typically single-cable bulkhead modules that allow barrier penetration while providing sealing and strain relief. They are sometime configurable to work with any cable within a specified size range. Important specifications to consider when searching for cable glands include cable diameter, mounting hole diameter, and adjustable diameter. The cable diameter specifies the diameter of the cable that can be fed through the cable gland. The mounting hole diameter refers to the diameter of the barrier or bulkhead hole into which the gland is to be installed. The adjustable diameter is the cable gland can be adjusted to fit various sizes of cable.
Common applications for cable glands include aerospace, cleanroom, fire protection, industrial, marine, panel or enclosure, power or utility, railway, and telecommunications. Aerospace cable glands are designed and rated for use on aircraft or space vehicles and/or equipment; may include applicable approvals for military and/or aircraft use.
Cleanroom cable glands are suitable for use in a cleanroom environment with the associated properties of maintaining positive pressure, prevention of dust and fluid ingress, etc. Fire protection glands are designed and rated for prevention of fire propagation across the bulkhead or barrier. Industrial glands are used in industrial environments such as factories, process plants, mills, etc.
Marine glands are designed for application on ships, offshore mining and drilling settings, or other marine applications.
Panel or enclosure cable glands are specifically designed and rated for penetration into electrical panels and/or electromechanical assembly enclosures.
Power and utility glands are designed for use with public utility equipment such as power transmission, distribution, and high voltage equipment.
Railway glands are designed for use on trains and associated installations.
Telecommunications glands are designed for used with communications cable or conduit. Choices for gland mounting include adhesive or compound, flanged or bolted, threaded or nut mount, welded, and cast. Materials of construction available for glands include aluminum, steel, stainless steel, and plastic.

Common features for cable glands include firestop, explosion proof, EMI or RFI shielding, and pre-terminated cable accommodation. Firestop cable glands are designed to withstand fire propagation through barrier. Explosion proof cable glands are designed for some level of explosion safety. EMI and RFI shielding and associated grounding features are used minimize or eliminate electromagnetic (EMI) and radio frequency interference (RFI). Transits configured to accommodate cables with end connectors or terminations already installed; transit can typically be opened up to allow termination pass through and enable subsequent resealing.
