2.3 Extension Module and 940 Professional IC Vario
The 942 Extension Module Vario units are fitted directly to the 940 Profes-
sional IC Vario and connected to it via the connection cable provided.
Extension modules have no power supply of their own, but rather draw
the electricity they require from the instrument to which they are con-
nected.
Extension modules can be placed in 3 different ways:
￭
Installed between the instrument and bottle holder (3- A ) .
￭
Installed between the instrument and base tray (3- B ) .
￭
Stacked next to the instrument (3- C ) . In this case, we recommend
ordering a separate base tray (6.2061.110) and a separate bottle
holder (6.2061.100) for the stack.
