DANGER: Danger of explosion
Danger of explosion when working on the device.
▸
Ensure no explosive atmosphere is present when working on the device.
DANGER: Danger of explosion due to ignitable mixture in the components
If the filter and probe junction unit cover are not completely closed after working on the
device, sparks may escape to the outside and cause an explosion.
▸
Always close the filter, probe junction unit cover completely after working on the
device.
DANGER:
Risk for system safety through work on the device not described in these
Operating Instructions
Work on the device not described in these Operating Instructions or associated
documents can lead to unsafe operation of the measuring system and therefore
endanger plant safety.
▸
Only carry out the work on the device described in these Operating Instructions and
associated documents.
DANGER:
Danger of explosion through incorrect performance of work described in these
Operating Instructions
Incorrect performance of work in potentially explosive atmospheres can cause serious
injuries to people and damage during operation.
▸
Maintenance and commissioning tasks as well as checks should only be carried out
by experienced/trained personnel with knowledge of the rules and regulations for
potentially explosive atmospheres, especially:
– Ignition protection types
– Installation rules
– Zone classification
DANGER:
Risk of burns and poisoning from escaping hot and toxic gas in systems with
overpressure conditions
In systems with overpressure, hot and toxic gas can escape from the process
connection. This can lead to burns or damage to health.
▸
Always keep the process connection tightly closed.
▸
Pay attention to hot surfaces.
▸
