3.5 Mounting the extension module
Depending on their utilization, extension modules can be mounted either
on (between IC instrument and covering plate) or under (between IC
instrument and base tray) the IC instrument. The covering plate or the
base tray must be dismounted for this purpose.
As an alternative, an extension module can also be set up next to the 850
Professional IC instrument. We suggest in such cases that the extension
module be supplemented with its own base tray and covering plate. Base
tray (6.2061.110) and covering plate (6.2061.100) can be ordered as
additional options.
3.5.1 Preparing IC instrument
If the IC instrument was already being used before an extension module is
to be installed, then the following preparation work must be carried out:
1 Remove bottles and all other items standing on the covering plate
from the covering plate.
2 Switch off the instrument and disconnect from the mains supply.
3 Undo all cable connections:
￭ Mains cable,
￭ MSB cable,
￭ USB cable.
4 Unplug leak sensor.
5 Disconnect drainage tubing from the instrument.
6 Disconnect detector cable and remove detector(s) from the instru-
ment.
3.5.2 Mounting the extension module under IC instrument
Note
Before you begin make sure that the preparation work (see Chapter
3.5.1, page 9) has all been carried out.
1 Tilt the instrument sideways and lay it down flat.
