6. Electrical connections

The signal isolator SIRAX TI 807 is plugged onto a backplane
BP 902. A 96 pin connector (Model C, DIN 41 612) estab-
lishes the electrical connections between the transmitter
and the backplane. The pin connections can be seen from
Fig. 5 and 6.
Please refer to our backplane instructions for the back-
plane wiring.
Make sure that the cables are not live when
making the connections!
In the case of "Intrinsically safe" explosion-
proof versions [EEx ib ] IIC or [EEx ia] IIC,
the supplementary information given on the
type test certificate and also local regula-
tions applicable to electrical installations
in explosion hazard areas must be taken
into account.
Note that, ...
... the required electrical insulation and trans-
mission data agree with the data on the
nameplate of the SIRAX TI 807 (
signals and
... in the case of a signal isolator with current
outputs 0...20 mA, the total resistance of
the external leads (receiver plus leads)
does not exceed the maximum burden of
1000 Ω (non-Ex version) or 500 Ω (Ex
version)! See "Output signal" in Section "4.
Technical data"!
... in the case of a signal isolator with voltage
output 0...10 V , the external receiver con-
nected across the output has a sufficiently
high internal resistance Ri

data"!
