11. Mounting

The isolating amplifier SIRAX TV 808 is plugged onto a
backplane BP 902.
When deciding where to install the transmitter
(measuring location), take care that the limits of
the operating temperature are kept:
– 25 and + 40 °C for standard instruments
– 20 and + 40 °C for instruments in Ex version!
11.1 Plugging the module into the backplane
Before inserting the SIRAX TV 808 into the
backplane, ensure that, ...
... the backplane wiring is in strict accordance
with the wiring diagram of the module
... the backplane is coded correctly ac-
cording to the section entitled "Mechani-
cal coding of the backplane". Read the
instructions for the backplane.
... the red coding insert has been removed
from the backplane for SIRAX plug-in
modules with a power supply of 24...60 V
DC/AC and that the power supply is cor-
rect for the module.
1. Clip the module base onto the top-hat rail.
2. If the backplane is mounted vertically, turn the quick release
screws on the module to a vertical position, respectively if
it is mounted horizontally, turn the screws to a horizontal
position.
3. Press the quick release screws inwards with the screwdriver
until there is an audible click.

12. Commissioning

Switch on the measuring input and the power supply. The
green LED lights continuously after switching on.
The power supply unit must be capable of supply-
ing a brief current surge when switching on. The
isolating amplifier presents a low impedance at the
instant of switching which requires a current I
of ...
≥ 160 mA for the version with a power sup-
... I
start
ply range of 24 – 60 V DC/AC
or
≥ 35 mA for the version with a power supply
... I
start
range of 85 – 230 V DC/AC

13. Maintenance

No maintenance is required.
14. Releasing the isolating amplifier
1. Rotate the quick release screws 90° .
2. Withdraw the plug-in module.
