Position the extension module in such a way that the capillary connections
can be kept as short as possible. If several extension modules are utilized,
then they should all be installed in the same location, either above or
below. If this is not possible, then the extension modules that are located
at greater distances from one another must be connected with one
another by means of the longer 6.2156.070 connection cable (available as
optional accessory).
