Fig. 5. Withdrawing the device.
There are two parts to the casing, the shell (8) and the cover
(9). They are held together by robust pegs and can be simply
assembled manually. The casing can be opened by pressing
the pegs (10) and (11) inwards one after another using a
screwdriver and applying pressure to lift the casing cover on
the connector side until the pegs release.
To assemble the casing, insert the guides into the casing
shell and press the two halves together using light pressure
until the pegs snap into place.

9. Electrical connections

The power pack SIRAX B 811 is plugged onto a backplane
BP 902. A 96 pin connector (Model C, DIN 41 612) establishes
the electrical connections between the power pack and the
backplane. The pin connections can be seen from Fig. 6.
Please refer to our backplane instructions for the
backplane wiring.
Make sure that the cables are not live when
making the connections!
The 230 V power supply and 250 V contact
output is potentially dangerous!
In the case of "Intrinsically safe" explosion-
proof versions [EEx ia] IIC, the supplementary
information given on the Ex approval and
also local regulations applicable to electrical
installations in explosion hazard areas must
be taken into account.
Note that, ...
... the data required to perform the electrical
... the input and output cables should be twisted
In all other respects, observe all local regulations
when selecting the type of electrical cable and
installing them!
