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).
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
 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.
