•
Cable, wire entries and closing screws must be certified acc. to ignition protection type Flame-
proof enclosures "d". Cable, wire entries and closing screws of simple design must not be used.
•
Separately certified cable and wire entries can determine the permissible ambient temperature
range or the temperature classes
•
Only one threaded adapter is allowed per thread, when using a closing screw, threaded adapt-
ers are not allowed

Operation
•
Do not operate the device outside the electrical and thermal specifications given in this safety
instruction
•
Modifications on the instrument can influence the explosion protection and hence the safety
•
Modifications must only be carried out by employees authorized by VEGA
•
Note the relation between process temperature on the sensor/antenna and the permissible
ambient temperature on the electronics housing. For permissible temperatures, see the respec-
tive temperature tables. See chapter "Thermal data".
•
The information on mechanical wear in the operating instructions must be observed
•
The continuous operating temperature of the connection cable must be suitable for the tempera-
ture range of the application
•
Only original spare parts or spare parts approved for the purpose may be used for repairs
•
The VEGAPULS 6X must be connected via suitable cable gland or conduit systems that are in
conformity with the requirements of the standards and provided with a separate type approval
certificate. When connecting the VEGAPULS 6X to conduit systems, the corresponding sealing
facility must be connected directly to the housing. Keep the type and size of the threads in mind:
The thread names are mentioned on the type label
•
Unused openings must be covered according to the standards. The red thread or/dust covers
screwed in when the instruments are shipped (depending on the version) must be removed
before setup and replaced by cable entries or closing screws suitable for the respective ignition
protection type and IP protection.
•
The connection cable of VEGAPULS 6X has to be wired fix and in such a way that damages can
be excluded
•
Lids must not be opened if there is a hazardous atmosphere. The housing lids are marked with
the warning label:
VEGAPULS 6X
