functions can result. Always mount the universal transmitter in an upright posi-
tion. Do not under any circumstances install the universal transmitter without
rain protection with the lid facing upwards (danger of retained humidity and pen-
etration of moisture).
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 the universal transmitter are
described in the following chapters:
 Mounting with sun shield SSH/IQ:
(see section 3.6.2).
 Mounting to the sun shield SD/K 170
The sun shield SD/K 170 provides room for the universal transmitter. The sun
shield can be mounted to 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 universal transmitter is permanently fixed to a wall. For wall mounting,
use the WMS/IQ mounting set (see chapter 10 A
CCESSORIES AND OPTIONS
).
 Panel mounting:
The universal transmitter is mounted in the aperture of a switch panel. The
dimensions of the aperture are 138 mm x 138 mm. The panel may not be
thicker than 10 mm (section 3.6.5).
To mount the interface (-MOD) of the DIQ/S 281-MOD behind the switch
panel, use the PMS/IQ-X accessory (see section 10).
 Top hat rail mounting:
The universal transmitter 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 3.6.4).
The following chapters describe the mounting of the universal transmitter.
