WARNING!
Before installation, usage and operation, ensure that the appropriate temperature
transmitter/switch has been selected in terms of measuring range, design and specic
measuring conditions.
Non-observance can result in serious injury and/or damage to
the equipment.
WARNING!
Observe the working conditions in accordance with chapter 3 “Specications”.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The temperature transmitter/switch is used to convert temperature into an electrical signal indoors and
outdoors.
The instrument has been designed and built solely for the intended use described here, and may only
be used accordingly.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the temperature switch outside of its technical specications requires the
instrument to be taken out of service immediately and inspected by an authorized NOSHOK service
engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
personnel who have the qualications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training, knowledge
of measurement and control technology and on their experience and knowledge of country-specic
regulations, current standards and directives, are capable of carrying out the work described and
independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids,
and refrigeration plants, compressors, etc., in addition to all standard regulations, the
appropriate existing codes or regulations must also be followed.
WARNING!
Residual media in the dismounted temperature switch can result in a risk to persons, the
environment and equipment.
Take sucient precautionary measures.
