5.8 Operation in potentially explosive environments:
Gas explosion
prevention:
• The operation in other explosive atmospheres is not permissible.
• It is not permissible to make any alteration to equipment that is used in
potentially explosive environments.
6. Mounting
The six versions of the transmitter differ in their mechanical design. Two of
them are intended for mounting directly on the device being measured. The
others are equipped with a mounting bracket or a fl ange. The relationship
between the three types of mounting, or more precisely the corresponding
cut-out diagrams and the different versions of the transmitter can be seen
from Table.

Three M6 screws are needed for the "directly" mounted versions and four
M8 nuts and bolts for these "with a bracket" or "with a fl ange". The screws,
respectively nuts and bolts are not supplied, because the required length
varies according to the thickness of the mounting surface.
When deciding where to install the transmitter (measuring loca-
tion), take care that the "ambient conditions" given in Section
"5. Technical data" are not exceeded.
Make the cut-out or drill the holes in the item onto which the transmitter is
to be mounted according to the corresponding drilling and cut-out diagram
given in Table 1 and then fi t the transmitter.
