3.2.2 Power supply
The line power supply unit of the MIQ/Blue PS can be used for the
exclusive supply of an IQ S
ENSOR N ET island. In any case, a separate
power rating has to be made for each IQ S ENSOR N ET island.
Power delivery
Compatibility with other
line power supply units
If the installation of further line power supply units should be necessary,
please note the following: If other power supply modules (e.g. MIQ/PS)
are installed on the IQ S
ENSOR N ET island, the line power supply unit of
the MIQ/Blue PS is automatically inactive. Connecting the MIQ/
Blue PS line power supply unit to a power supply remains ineffective
here. In this case, the MIQ/Blue PS is a consumer with a power con-
sumption of 0.6 W in the power rating.
Example Problem:
 An IQ S
ENSOR N ET island should consist of the following compo-
nents plus the MIQ/Blue PS:
 In this example, the MIQ/Blue PS and the MIQ/CHV PLUS should
be mounted as a stack.
 The IQ S
ENSOR N ET system should be supplied with 100 ...
240 V AC.
Solution/proceeding:
 First it is assumed that the MIQ/Blue PS suffices for power supply.
It does not have to be taken into account as a consumer. In the worst
case, i. e. with a docked MIQ/TC 2020 XT, the power requirement of
all components is 7.2 W. Power losses in cables do not have to be
taken into account due to the stack mounting.
 Power rating: The calculated power requirement is greater than the
maximum power delivery of the MIQ/Blue PS line power supply unit.
Therefore, an additional power supply module has to be installed
(e.g. MIQ/PS).
 New power rating: The MIQ/Blue PS has to be counted as a con-
sumer as well. Therefore, the power consumption is now 7.8 W.
24 V DC operation: 24 W
100 ... 240 V AC operation: 7 W
