Mechanical Coding Of The Plug-In Module; Electrical Connections - GMC SIRAX PT 602 Mode D'emploi

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 Figure 3.

8. Electrical connections

The measurement transmitter SIRAX PT 602 is plugged onto
a backplane BP 902. A 96 pin connector (model C,
DIN 41 612) establishes the electrical connections between
the transmitter and the backplane. The pin connections can
be seen from Fig. 4.
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!
Also note that, ...
... the data required to carry out the prescribed
measurement must correspond to those
marked on the nameplate of SIRAX PT 602
( measuring input,
power supply!)
... the total loop resistance connected to the output
(receiver plus leads) does not exceed the
maximum permissible value R
"Measuring output" in Section "6. Technical
data" for the maximum values of R
... the measurement input and output cables
should be twisted pairs and run as for 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!
