The Code of Practice for ‘e’ type enclosures is specified in IEC60079-
14. The installer and all service personnel should be familiar with the
relevant sections of these documents.
If only one gland entry is used, the black Ex e sealing plug must be
fitted to the unused entry.
1. Place the telephone on its base on a firm horizontal surface.
2. Using a 5mm Allen key, release the Front Casing from the Rear
Casing. The screws are not captive in the Front Casing.
3. Noting their positions, disconnect the ribbon cable(s) and the ringer
cable from the front section. See 3.6.
4. Take care when removing the Front Casing from the Rear Casing
and storing the Front Casing not to damage the internal electronics,
specifically the headset switch terminals or headset socket if fitted.
To do so will violate the certification of the telephone product.
5. Check the condition of the sealing gasket (in the recess running
round the edge of the front section), especially if the telephone has
been previously used. If this seal shows any sign of damage or
deterioration, it must be replaced prior to installing the telephone.
6. Remove the RED blanking plug from the cable entry hole leaving the
Ex e certified (usually BLACK) blanking plug in situ.
NOTE: The Ex e plug must be used to seal the unused gland
hole; failure to do so will invalidate the certification of the
telephone product.
7. Select the appropriate size Ex gland for the cable used.
8. Take care when inserting the selected gland into the threaded cable
entry hole. Follow the gland manufacturer’s instructions particularly
with respect to sealing, installation and earthing.
9. After the glands have been fitted, select the required mounting
method and follow the appropriate instructions below.
