Siemens Temperature monitor / safety temperature limiter for flue gas ducts RAG-TW.1/-ST.1 CE1N1211en
Building Technologies 21.12.2010
Notes
Installation Instructions are enclosed in the package.
It must be ensured that there is sufficient clearance above the unit for viewing
through the window, for adjusting the limit temperature and for removing and
replacing the unit, if required.
Fit protection pocket with flange to the flue gas duct. Insert spacer in the pocket
and tighten the screw. Insert capillary tube and spacer in the protection pocket. Fit
base of the unit to the spacer and secure it by tightening the screw.
Only authorized personnel are allowed to set the limit temperature.
Only authorized personnel are allowed to wire up the unit. The cables used must
meet the insulation requirements for mains voltage.
If the expansion liquid escapes from the capillary tube, the contact opens (fail-safe
design). In that case, the contact remains open and, for this reason, the unit must
not be used as a component of the safety loop.
The wiring must be made according to the connection diagram and in compliance
with local regulations.
Caution: Prior to opening the housing, the unit must be disconnected from power.
Protective earth must be connected in compliance with the regulations.
In terms of disposal, the products are classified as electronic scrap conforming to
the European Directive 2002/96/EG (WEEE) and must not be disposed of as
domestic waste. The relevant national regulations must be observed and the
product must be disposed of through the appropriate channels. Local and currently
valid legislation must be observed.
