Auteldac 5
3.4.1
Connection to the Telecommunications Network
The telephone line is connected to the terminals marked A and B as
shown on the terminal cover. The terminals marked “TE” are for
connection to a telecommunications earth – an optional connection
back to the PABX to allow ELR (Earth Leg Recall) to function if
required.
There are two sets of telephone line terminals – connected in
parallel to allow the connection of other approved equipment in
parallel with Auteldac 5 without the need for a junction box. Note
that the order of terminals is reversed between the two sets. The two
sets of terminals are interchangeable.
To maintain safe operation of this product the telephone line must
not exceed the following:
•
U
m
= 253V rms
•
Rated voltage on hook = 70Vdc + Ring Voltage, where the
maximum ring voltage can be either:
•
70V rms if continuous, or
•
100V rms if cadenced with a duty cycle having a
maximum on time of 50%
Note: ring voltage maximum frequency is 60Hz
•
Rated voltage off hook = 40V
•
Maximum power = 15W (in accordance with EN60950-1
Clause 1.4.11 and 1.2.13.8)
Note: these are safety parameters only and correct operation under
these conditions is not implied.
For correct operation the telephone line should comply with the
