• 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.
Devices with explosion prevention must be operated
in accordance with the stipulations of the operating
instructions. The relevant laws, regulations and stan
-
dards for the planned application must be observed.
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
flange
. 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

screws are needed for the
“directly”
mounted versions and four
M8
nuts and bolts for these
“with a bracket”
or
“with a flange”
. 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 fit the transmitter.
