3.5 Onsite installation of DIQ/S 182-XT-4-PR and
MIQ modules
3.5.1 General information
The DIQ/S 182-XT-4-PR 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.

Components 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 the DIQ/
S 182-XT-4-PR 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).
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.
