3.4.2
Earth Connection (Headset Version Only)
IMPORTANT:
If fitted with a headset socket, Auteldac 5
must
be
connected to an equipotential bonding system for the whole area in
which the intrinsically safe equipment is being used.
Versions with a headset socket are supplied with earth studs and
link wires, and must be connected to earth as shown.
This earth connection is a condition of the certificate for headset
versions.
3.4.3
Gland continuity connection
Auteldac 5 is provided with 2 earth bonding screws which can be
used as a continuity connection between glands if 2 metal glands
are used. If the unit does not have a headset socket, reverse one of
the earth bonding screws as shown below, paying particular
attention to the sequence of nuts and washers fitted, to provide an
external continuity point.
If the unit is fitted with a headset socket, one of the earth bonding
screws will already be in this position, (see above) in which case this
screw can be used for gland continuity as well.
3.4.4
Ring Relay Contact
(Galvanically isolated, volt-free contact)
The connection from the telephone to the external load must be
installed such that the apparatus continues to comply with the
requirements of EN 60950-1.
