Operation
5.1 Starting up for the first time
5.2 Operation
You can open the connection head when live (thanks to the "intrinsic safety" protection type) even
in explosive areas to work on the electrical connections for measuring and setting purposes (e.g.
to configure a temperature transmitter):
DANGER!
To prevent injury and material damage, only operate industrial thermometers under the
following conditions:
• The equipment was installed and connected in accordance with the manufacturer's
instructions.
• At the operator's request, a test was conducted prior to start-up to ensure the correct
installation and connection.
• The check prior to start-up was in compliance with the national regulations for checks before
start-up.
DANGER!
To avoid injury and material damage, only operate the measuring inserts under the following
conditions:
• Temperatures, pressures and electrical limit values are in the manufacturer's specified
range.
• The equipment parts necessary for safety are effective in the long run, never disable them
during operation!
• When using flammable products, the thermowell must be included in the periodic pressure
tests of the system.
CAUTION!
When using the thermometer, and in particular after work to the connection head, ensure that it
is closed properly. Otherwise the degree of IP protection is not guaranteed.
