The terminals 7 and 8 are intended for the connection of dynamic
receiver insets, like the ones used in second earpieces and headsets.
This output thus can be used for connecting a second earpiece or a
headset, which means that a second earpiece and a headset cannot be
connected simultaneously.

To connect accessories, you must replace the blind plugs screwed into
the telephone housing by explosion-proof cable glands (M20x1.5).
Before connecting intrinsically safe accessories, and if a system
certificate for the intended connection does not exist, the constructor
should perform an evaluation of the intrinsic safety according to
EN 60079-25.
The technical data for the evaluation of the intrinsic safety can be found
in the chapter "Characteristic data".
Further information see EN 60079-14.
A metal bracket is supplied for hanging up the intrinsically safe second
earpiece or headset. The metal bracket should be attached to the
telephone by means of the two threaded bushes in the floor of the
telephone housing. The corresponding bores in the metal bracket can
be used to screw the bracket securely onto to the housing floor (see
overview of the device on page 6). Thus, if the constructor wants to use
the metal bracket, the first thing he has to do, is to fix it to the housing
floor. Subsequently, the device may be mounted on the wall.
