Mounting; Electrical Connections - Camille Bauer WT707 Mode D'emploi

6. Mounting

The twelve versions of the transmitter differ in their mechanical
design. Four 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 2.

The M6 screws are needed for the "directly" mounted versions
and four M8 nuts and bolts for those "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 location), take care that the ambient
conditions given in Section 5 "Technical data"
are not exceeded.
When installing or servicing intrinsically safe
(Ex) instruments with enclosure made from
synthetic material, care must be taken to avoid
electrostatic charges.
Make the cut-out or drill the holes in the item onto which the
transmitter is to be mounted according to the correspon-
ding drilling and cut-out diagram given in Table 2 and then
fit the transmitter.
Pay attention when aligning and tightening the
transmitter that the electrical zero and the zero
of the item being measured coincide.
The holes in the mounting bracket and the flange
are elongated for this purpose and permit the
transmitter to be rotated in order to adjust the
electrical zero to coincide with the zero of the
measured device.
Similarly, it is advisable to elongate the three holes
(6.5 mm diam.) drilled for "directly" mounted
versions (see upper drilling and cut-out diagram
in Table 2).
The electrical zero of the transmitter is marked
on the end of the shaft and on the outside of the
casing (see diagrams):
– left for rotation transmitters
with the range of 0 to ...
– right for rotation transmitters
with V characteristic ranges.

7. Electrical connections

Either a plug-in connector or screw terminals and cable
glands are provided for making the electrical connections
to the transmitter. Of the twelve versions of the transmitter,
six have connectors and six screw terminals and cable gland
(see Table 2).
Make sure that the cables are not live when
making the connections!
The 230 V power supply is potentially
dangerous!
