3.7 Onsite installation of DIQ/S 182 XT-4-PR and
MIQ modules
3.7.1 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.
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-PR 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.
