Connection diagram
The device complies with the
requirements of the ATEX direc -
tive 2014/34/EU, the EMC-
directive 2014/30/EU and the low
voltage directive 2014/35/EU.
The conformity with the above
directives is confirmed by the CE
sign.

.
Telephone network (not intrinsically safe)
Terminals No. 7 and 8 in accordance with 9 and 1 0
Un = AC 90 V / f = 25 Hz
Um_AC = AC 1 00 V / f = 20 … 68 Hz
Um_DC = DC 66 V
Um = 1 20 Veff
AC and DC voltage parts can be superimposed.
Permissible conductor cross-sections are 0.2 to
4.0 mm rigid or 0.2 to 2.5 mm flexible.
Only 2 or 4-core lines may be used.

.
Potential-free relay contacts (not intrinsically safe)
Terminals No. 1 /3 or No. 4/6
Umax = AC 250 V
Imax = 5 A
Pmax = 1 00 VA
In this case only lines with a core cross-section
of 1 .5 mm to 4 mm may be used.
Or
Umax = DC 230 V
Imax = 0.5 A
Pmax = 1 00 W
In this case only lines with a core cross-section
of 0.75 mm to 4 mm may be used.
Or
Umax = DC 50 V
Imax = 1 A
In this case only lines with a core cross-
section of 0.75 mm to 4 mm may be used.
Or
Umax = DC 30 V
Imax = 5 A
Pmax = 1 00 W
In this case only lines with a core cross-
section of 1 .5 mm to 4 mm may be used.
The terminals no. 2 and 5 according to the
connection diagram may not be used. Only 2
or 4-core lines may be used.

.
The telephone network is securely and galva-
nically isolated from the potential-free relay
contacts.
4
.
The two potential-free relay contacts are
securely and galvanically isolated from one
another up to a voltage of 440 Veff.
The voltage may not exceed 250 Veff at an
individual relay contact.
