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:
Feature
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 construction
The glands should only be used with substantially round and compact cables with extruded bedding (i.e. effectively filled cables).
Interpretation of Markings.
Markings on the outside of this gland carry the following meanings:
Cable Gland Type & Size E-a-b-IE-c-FR-ddd-eee-IP67-nn
a
= Seal Type
1 = Neoprene (black - temp range –20º to +85ºC)
2 = Neoprene with Continuity washer for lead sheathed cable
3 = Silicone (white or red - temp range –60º to +180ºC) ;
b
= Armour clamping
W = single wire armour
XZ = woven steel wire/tape
L
= Kit for W and XZ
IE
= Integral Earth stud option
c
= Main component material
none = brass
S = stainless steel ;



Protection Concept and Gas Groups EEx d IIC / EEx e II (CENELEC & ATEX) ;
Ex d IIC / Ex e II (IEC) ; Ex d = Flameproof ; Ex e = Increased Safety ; IIC =
suitable for Gas Group IIC (e.g. hydrogen) ignitable gas/air mixtures, and also
Groups IIB and IIA ; II = combined Gas Group
Certificate Numbers:
(ATEX) SIRA 01ATEX1271X The ‘X’ suffix denotes Special Conditions for Safe Use’ (see
below)
(IEC) IECEx SIR 05.0020X The ‘X’ suffix denotes ‘Conditions of Certification’ (see below)

potentially explosive gas mixtures or combustible dusts


ATEX Special Conditions for Safe Use
1. These glands must not be used with EEx d IIC enclosures with a volume greater than 2 litres.
2. These glands must not be used with enclosures where the temperature at the point of mounting exceeds -20°C to +85°C using neoprene seals, or –60° to +180°C using silicone seals.

IEC Ex Conditions of Certification
1. These glands are certified with one specific size of flameproof sealing ring per gland size as supplied.
2. These glands must not be used with enclosures where the temperature at the point of mounting exceeds -20°C to +85°C using neoprene seals, or –60° to +180°C using silicone seals.
