3.6 Installation of the MIQ modules at the installation location
3.6.1 General information
The IQ S
ENSOR
N
ET
system has a comprehensive program of mount
-
ing accessories, which can be used to adapt the installation to the most
varied requirements.
Note
MIQ modules installed outside must always be protected by a sun
shield against the effects of the weather (snow, ice and direct solar ra
-
diation). Otherwise, malfunctions can result. Always mount
MIQ modules vertically. Do not under any circumstances install
MIQ modules without rain protection with the lid facing upwards (dan
-
ger of retained humidity and penetration of moisture).
Installation options The most important types of installation for MIQ modules and module
stacks are described in the following chapters:

Mounting on a mounting stand with the SSH/IQ sun shield:
The SSH/IQ sun shield provides enough space for one unit of up to
three stacked MIQ modules and a docked terminal (section 3.6.2).

Mounting on the SD/K 170 sun shield
The SD/K 170 sun shield provides enough space for a single
MIQ module with a docked terminal. The sun shield can be mounted
on round or square section pipes (e.g. rails) with the aid of the MR/
SD 170 mounting kit (section 3.6.3).

Wall mounting:
The back MIQ module of a module stack or a single MIQ module is
permanently screwed to a wall. For wall mounting, use the WMS/IQ
mounting set (see chapter 12 A
CCESSORIES AND OPTIONS
).

Panel mounting:
The front MIQ module of a module stack or a single MIQ module is
installed in the aperture of a panel. The aperture dimensions are
138 x 138 mm + 1 mm (maximum thickness 15 mm) according to
DIN 43700 or IEC 473 (section 3.6.4).

Top hat rail mounting:
The back MIQ module of a module stack or a single MIQ module is
mounted on a 35 mm top hat rail with the aid of a bracket in accor
-
dance with
EN 50022, e.g. in a control cabinet. The connection can be released
again with one simple movement (section 3.6.5).
Caution
No contact base may be mounted on the back of the module (danger
of short-circuit!) if the module is mounted on a wall, a sun shield, or a
top hat rail.
