2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate gas-actuated thermometer has been
selected in terms of measuring range, design and specic
measuring conditions.The compatibility of the wetted parts
of the process connection (thermowell, stem etc.) with the
medium must be tested.
Non-observance can result in serious injury and/or damage
to the equipment.

WARNING!
This is protection class 3 equipment for connection at low
voltages, which are separated from the power supply or
voltage by greater than AC 50 V or DC 120 V. Preferably,
a connection to an SELV or PELV circuit is recommended;
alternatively protective measures from HD 60346-4-41
(DIN VDE 0100-410).
Alternatively for North America:
The connection can be made in line with "Class 2 Circuits"
or "Class 2 Power Units" in accordance with CEC (Canadian
Electrical Code) or NEC (National Electrical Code).
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The gas-actuated thermometer is mainly used in the process industry to
monitor and control process temperatures.
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
The technical specications contained in these operating instructions
must be observed. Improper handling or operation of the instrument
outside of its technical specications requires the instrument to be
taken out of service immediately and inspected by an authorised WIKA
service engineer.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

WARNING!
Riskofinjuryifqualicationisinsucient!
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 qualications described below.
■
Keep unqualied personnel away from hazardous areas.
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-specic regulations,
current standards and directives, are capable of carrying out the work
described and independently recognising potential hazards.
2.3 Special hazards
WARNING!
Residual media in the dismounted gas-actuated
thermometer can result in a risk to personnel, the
environment and equipment. Take sucient precautionary
measures.
