WARNING!
Before installation, commissioning and operation, ensure
that the appropriate gas-actuated thermometer has been
selected in terms of measuring range, design and specific
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
