3.5 Connecting system components
3.5.1 General information
The IQ S ENSOR N ET system components are connected to form a
functioning unit in the following ways:
 Stacked mounting of MIQ modules
Up to three MIQ modules can be installed and mechanically
connected with one another to form a stack at a single location. The
contacts on the front and rear automatically create the electrical
connection between the MIQ modules in the stack (section 3.5.2).
 Distributed mounting of MIQ modules
Individual MIQ modules or an assembled module stack are installed
at various locations (for example, a central control unit and an
MIQ branching module for connecting IQ sensors at the edge of the
basin). The spatial distance is bridged with the aid of the SNCIQ or
SNCIQ/UG cable (section 3.5.3).
 Connection of IQ sensors:
IQ sensors are connected to an MIQ module with the aid of the
SACIQ cable. This cable is available in different lengths. The
MIQ module must have a free SENSORNET connection on the
terminal strip. On the sensor side, the connection is made via a plug
that is standard for all IQ sensors (section 3.5.4).
 Docking of a terminal unit:
A terminal unit is attached to the lid of a free MIQ module with the
aid of a quick-release locking mechanism (section 3.5.5).
Caution
Distributed mounting is only allowed in a star configuration. The
system must nowhere be closed to form a ring. Only use the
assembly material provided for the installation.
