3.7 Onsite installation of DIQ/S 182 XT-4 and
MIQ modules
3.7.1 General information
The DIQ/S 182 XT-4 and the DIQ and MIQ modules have a
comprehensive program of mounting accessories, which can be used
to adapt the installation to the most varied requirements.
Caution
Components installed outside must always be protected by a sun
shield against the effects of the weather (snow, ice and direct
solar radiation). Otherwise, malfunctions can result. Always
mount the DIQ/S 182 XT-4 vertically. Do not under any
circumstances install MIQ modules without rain protection with
the lid facing upwards (danger of retained humidity and
penetration of moisture).
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.
Installation options The most important types of installation for theDIQ/S 182 XT-4 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 the DIQ/
S 182 XT-4 and two MIQ modules (section 3.7.2).
 Mounting on the SD/K 170 sun shield
The SD/K 170 sun shield provides room for the DIQ/S 182 XT-4.
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 3.7.3).
 Wall mounting:
The DIQ/S 182 XT-4 or MIQ module is permanently screwed to a
wall. For wall mounting, use the WMS/IQ mounting set (see
chapter 11 A
CCESSORIES AND OPTIONS ).
 Panel mounting:
The DIQ/S 182 XT-4 or the MIQ module is installed in the aperture
of a panel. The dimensions of the aperture are 138 x 138 mm
+ 1 mm. The panel may not be thicker than 15 mm (section 3.7.4).
 Top hat rail mounting:
The DIQ/S 182 XT-4 or the MIQ module is mounted on a 35 mm top
hat rail with the aid of a bracket, e.g. in a control cabinet. The
connection can be released again with one simple movement
(section 3.7.5).
How to mount the DIQ/S 182 XT-4 is described in the following
chapters. MIQ modules are mounted in the same way.
