Application / Properties
All the cable entries and components covered by these operating and mounting instructions are suited for use in enclosures and apparatus in the type of protection ”Increased Safety”. Trumpet-shaped cable glands are used for feeding flexible cables into enclosures and apparatus. The fitting of seal inserts one inside the other or the interchanging of seal inserts of different entries to reduce the cable opening is not permitted. Reducing glands can be used to reduce the size of threaded or through holes in enclosures to a smaller thread size. Blanking plugs are used to seal metric COOPER CROUSE- HINDS cable entries and COOPER CROUSE-HINDS multiple entries. Screw glands are used to seal unused through and threaded holes. Any condensation in the apparatus can escape via drain plugs (see 6.1, Mounting). Applications other than those described are not permissible without a written declaration of consent from Messrs. COOPER CROUSE-HINDS. The instructions according to section 7 of the operating instructions shall be observed during operation. The sole responsibility with respect to the suitability and proper use of these entry components with regard to the basic conditions of these instructions (see Technical Data) lies with the operator. X ATEX – IEC The EC- Type Examination Certificate and any future supplements thereto shall, at the same time, be regarded as supplements to the EC-Type Examination Certificates PTB 99 ATEX 3128 X and PTB 99 ATEX 3101 X.

Installation

The relevant national regulations and the generally recognized rules of engineering apply to the installation and operation. (IEC/EN 60079-14). The improper installation and operation of enclosures can result in the invalidation of the guarantee. Observe the special operational conditions in accordance with IEC/EN 60069-14.

X ATEX – IEC Only fixed cables may be used. The operator shall ensure that appropriate strain relief is provided. This is not required for trumpet-shaped glands.
X ATEX – IEC The degree of protection IP66 is only attained if the seals and cable entries are installed correctly.
X ATEX – IEC Cable entries that are only suited for low impact energy shall be built into an enclosure in such a way as to protect them from mechanical impact energy.
Attention: In case of unused cable entries, remove their protective cover and close the entries with a blanking plug (see Technical data).

Mounting

Prior to mounting, ensure that the threads of the entry components match the threads of the apparatus or enclosure. If the entries and components are to be screwed directly into the walls, the wall thickness of the apparatus shall be at least 4 mm.
Counter-nuts shall be used if enclosure walls are less than 4 mm thick. The minimum thickness of the enclosure wall shall be 1.5 mm.
The use of entry elements with damaged or dirty threads can impair the IP degree of protection.
Imported Cables and wiring shall be relieved of tensile forces (eg with a cable clamp).

Cable entries (KLE)
The intermediate gland (see Fig. 1)

of the cable entries shall be fitted with a suitable tool, e.g. fork, ring or box spanner. It is mounted directly in the threaded hole or via the through hole of the enclosure EATON-GHG-960-x-e-i-Cable-Glands-
fig-15

If the sealing surfaces are uneven, seals shall be used between the enclosure wall and the intermediate gland . Counter-nuts shall be used for walls with a thickness of less than 4 mm (see Fig. 2). Cables are fed in as shown in Fig. 4. The seal inserts shall be chosen to suit the respective cable diameter (Page 13 Figs. A, B, C and D). Use COOPER CROUSE-HINDS spanners with a side opening can be used to facilitate the tightening of the pressure screw when the cable entry has been mounted

Order No. GHG 960 1951 R0001 for Set 1 (M12, 16, 20, 25, 32 and 40) Order No. GHG 960 1951 R0002 for Set 2 (M50 and M63) To ensure the required minimum degree of protection, the gland body and the pressure cap shall be tightened with the given test torques (see Technical Data). When tightening the pressure cap, the gland body shall be prevented from turning with a suitable tool, e.g. a spanner.
Overtightening can impair the degree of protection.
Optionally, cable entries with color-coded (light blue) pressure screws can be used for intrinsically safe circuits (see main COOPER CROUSE-HINDS catalog for order numbers).

Blanking plugs
X ATEX – IEC Blanking plugs of the types GGH 960 6107 P or GHG 960 1944 R may only be used in conjunction with cable entries of the types GHG 960 92 P** or GHG 960 19 R**.
The following shall be observed when mounting blanking plugs for COOPER CROUSE-HINDS metric cable entries (see Fig. 6):

Only the blanking plug associated with the KLE shall be used.
When closing the gland with a blanking plug, always use sealing inserts 1+2!
The head of the blanking plug shall, as shown in , be on the outside.
The blanking plug shall be pushed into the KLE until it reaches the stop.
The pressure screw of the KLE shall be tightened down as described in 6.1.1.

Screw plug
The screw plug shall be screwed tightly into the threaded hole in the enclosure using a suitable tool, e.g. 8 mm socket head spanner or a suitable screwdriver. A counter-nut shall be used for through holes or enclosures that are less than 4 mm thick. An additional seal shall be used for uneven sealing surfaces. In general, the M50 screw plug shall be mounted together with the seal supplied.
Trumpet-shaped gland
A suitable tool, e.g. a fork spanner, shall be used for mounting the intermediate gland in the trumpet-shaped gland in such a way that it cannot twist. It is necessary to ensure that the gland cannot twist once the cable has been fed in and the trumpet-shaped gland mounted (e.g. by using a counter- nut, see Figs. 7 + 8). A counter-nut shall be used for through holes or enclosures that are less than 4 mm thick. When mounting, a seal shall always be used between the enclosure wall and the intermediate gland (see Fig. 7).
The following describes the mounting of the cable in the trumpet-shaped gland, as shown in

Cut out the individual rings of the ”onion ring” seal insert to match the respective cable diameter.
After feeding in the cable, that has been cut to length and has the seal mounted, into the intermediate gland, screw the trumpet-shaped gland tightly into the intermediate gland to seal off the cable.
Then mount the pull relief on the trumpet-shaped gland.

It is necessary to ensure that there is sufficient pull relief, that damage to the cable is not possible, and that the trumpet-shaped gland cannot twist.
Reducing gland
A suitable tool, e.g. a fork, ring or box spanner, shall be used for screwing the reducing gland tightly into the threaded hole in the enclosure. A counter- nut shall be used for through holes or enclosures that are less than 4 mm thick. An additional seal shall be used for uneven sealing surfaces.
Screwing several reducing glands one inside the other to reduce the size of the entry thread is not permitted.

Drain plug

A suitable tool, e.g. a fork, ring, or box spanner, shall be used for screwing the drain plug tightly into the threaded hole in the enclosure.
An additional seal shall be used for uneven sealing surfaces.
The drain plug shall be mounted at the lowest point of the apparatus or enclosure
The minimum wall thickness may not be less than 4 mm.
Entry components shall be screwed in tightly to ensure the specified minimum degree of protection (see Technical Data for test torques).
Overtightening can impair the degree of protection.

Putting into operation
Prior to putting the mounted entry components into operation, the tests specified in the individual national regulations shall be performed. In addition to this, prior to putting the entries into operation, the correct mounting shall be checked in accordance with these operating and mounting instructions and any other applicable regulations. In locations where they are particularly at risk, the entries shall be safeguarded against being torn out of the apparatus or enclosure walls by external mechanical influences (e.g. by forklift trucks, by knocking, or similar).
Maintenance / Servicing
The valid national regulations for the servicing/maintenance of electrical apparatus for use in potentially explosive atmospheres shall be observed (e.g. IEC/EN 60079-17). The necessary intervals between servicing depend upon the specific application and shall be stipulated by the operator according to the respective operating conditions. As part of the routine testing, above all, parts on which the explosion protection depends shall be checked ( e.g. intactness of entry components and seals). Pressure screws of cable entries and trumpet-shaped glands of trumpet-shaped cable entries shall be checked at regular intervals to ensure that they are screwed in tightly and, if necessary, they shall be tightened down. If, in the course of servicing, it is ascertained, that repairs are necessary, section 8 of these operating instructions shall be observed.
