EMC note USA (FCC):
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.

4 Intallation
4.1 Mounting the Enclosure
1. Only for model T2 (duct mounting). Drill the hole for inserting the probe into the duct wall,Fig. 7 on
page 11. The relevant position of top left mounting screw of the back cover with respect to the probe
center:
2. FixthebackcoverofEE23ontothewall/panelusing4screws(diametermax.4.2mm(0.2”);not
included in the scope of supply).
The device shall be mounted with the cable glands pointing downwards or horizontal.
3. Wiretheterminalsinsidethebackcoveraccordingto„Fig.10Connectiondiagram“onPage12.
4. Insert the middle (active) part into the back cover. By this the connection pins of the middle part will
plug into the terminals of the back cover and thus realize the electrical connection.
5. Place the front cover onto the middle part and close tight the enclosure using the four screws included
in the scope of supply.
Drilling for round holes:
