8. Electrical connections
The isolating amplifier SIRAX TV 808 is plugged onto a
backplane BP 902. A 96 pin connector (model C, DIN 41 612)
establishes the electrical connections between the isolating
amplifier and the backplane. The pin connections can be
seen from Fig. 5.
Please refer to our backplane instructions for the back-
plane wiring.
Make sure that the cables are not live when
making the connections!
The 230 V power supply is potentially
dangerous!
In the case of “Intrinsically safe” explosion-
proof versions [EEx ia] IIC, the supplementary
information given on the Type Examination
Certificate and also local regulations appli-
cable to electrical installations in explosion
hazard areas must be taken into account.
Also note that, …
… the data required to carry out the prescribed
measurement must correspond to those marked
on the nameplate of SIRAX TV 808 (
measu-
ring input,
measuring output,
power
supply!).
… the total loop resistance connected to the
output (receiver plus leads)
does not
exceed the
maximum permissible value R
ext.
max., see
Meas-
uring output”
in Section “5. Technical data” for
the maximum values of R
ext.
!
… the measurement input and output cables should
be twisted pairs and run as far as possible away
from heavy current cables!
In all other respects, observe all local regulations
when selecting the type of electrical cable and
installing them!

7. Mechanical coding of the plug-in module
Where there is a danger of inserting a module in the
wrong slot, the possibility has to be excluded as
prescribed in EN 50 020, Section 6.3.2.
To this end,
the units must be supplied already equipped with
coding inserts as shown in Figures 3 and 4.
