3 Installation
3.1 Scope of delivery
The scope of delivery of the MIQ/24V is listed in the I
NSTALLATION
chapter of the system operating manual.
3.2 Installation in the IQ S
ENSOR
N
ET
The IQ S
ENSOR
N
ET
provides a number of options for integrating the
MIQ/24V mechanically and electrically in the system (stacked
mounting, distributed mounting, etc.). The individual types of instal-
lation are described in detail in the I
NSTALLATION
chapter of the system
operating manual.
Note
To achieve optimum heat transfer, it is recommended to always place
the power supply module at the back of a module stack.
Note
If there are several power supply modules in the IQ S
ENSOR
N
ET
, it is
helpful if all the power supply modules are connected to a single power
supply. As a result, the system can be easily switched on and off from
a single location.
3.3 Connecting the 24 V AC/DC supply
Warning
If the power supply is connected incorrectly, it may represent a
danger to life from electric shock. Pay attention to the following
points during installation:
!
! !
! The power supply must fulfill the specifications given on the
nameplate and in chapter 5 T
ECHNICAL DATA
(Safety Extra Low

by a trained electrician.
! ! ! !
The connection of the MIQ/24V may only be carried out when
the supply is not carrying any voltage.
! ! ! ! When installed in a building, a switch or power switch must be
provided as a disconnecting device for the MIQ/24V.
