Connecting
MIQ modules
There are two basic mounting variants for connecting the
MIQ modules:
 Stack mounting - permanent mechanical and electrical connection.
The housings of the MIQ modules are permanently mounted on one
another to form a stack. No cabling is necessary.
 Distributed mounting - electrical connection via cable.
Locally separated MIQ modules or module stacks are connected
with one another via the SNCIQ or SNCIQ/UG cable.
The following diagram shows an IQ S ENSOR N ET system with two
mounting variants (Fig. 1-3).

IQ sensors Up to 20 IQ sensors of any type can be used in the system
2020 XT USB. They can be connected to any MIQ module that has a
free connection for the IQ S
ENSOR N ET . The connection between the
IQ sensor and MIQ module is made via the SACIQ sensor connection
cable. The IQ sensor connection cable is connected with the plug head
connector of the IQ sensor via a screwable socket to form a watertight
connection. As a result, the IQ sensor can be quickly removed for
maintenance activities and then connected again.
