6. Mounting
All versions of the transmitter which differ in appearance by the type of shaft can
be mounted either directly or by means of 3 mounting clips to the item being
measured. The screws are not supplied, because the required length varies ac-
cording to the thickness of the mounting surface. Both methods of mounting and
the relevant drilling and cut-out plans can be seen from Table.
Mounting versions

4.5 low
When deciding where to install the transmitter (measuring
location), take care that the "Ambient conditions" given in
Section "5. Technical data" are not exceeded.
Make the cut-out and 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.
Pay attention when aligning and tightening the transmitter that the
transmitter zero and the zero of the item being measured coincide.
Alignment is achieved by rotating the transmitter.
To facilitate alignment in the case of "direct" mounting, it is recom-
mended to elongate the 3 mounting holes (diam. 3.2 mm).
When using mounting clips, the clips permit the transmitter to be
rotated to the correct position.
The electrical zero of angular transmitters with measuring ranges
0 to ...
° is marked on both the front and the back (see upper
illustration). It is only marked on the front, however, in the case of angular
transmitters with ranges having a V characteristic and at instruments
with both senses of rotation, see lower illustration.

7. Electrical connections

7.1 Electrical connections via sondering posts
There are 3 soldering posts (3)
on the back of the transmitter for
attaching the electrical connec-
tions. The soldering gosts suffi ce
Protection Class IP 00 according
to EN 60 529.

Note that, ...
... the data required to carry out the prescribed measurement must
correspond to those marked on the nameplate of the KINAX 3W2
(Range, Output, Supply voltage)!
... the total loop resistance connected to the output (receiver plus
leads) does not exceed the maximum permissible value R
"Measuring output" in Section "5. Technical data" for the maximum
values of R
... twisted cores must be use for the measured variable input and
output leads and routed as far away as possible from power cables!
In all other respects, observe all local regulations when selecting the
type of electrical cable and installing them!
In the case of "Intrinsically safe" explosion-proof versions with I.S.
measuring output, the supplementary information given on the Ex
approval and also local regulations applicable to electrical installations
in explosion hazard areas must be taken into account!
Solder the connections as shown in the corresponding wiring diagram (Fig. 7).
Do not excessively heat the soldering posts (3)!
Do not mechanical load the soldering posts (3)!
Solder using a small pencil bit soldering iron!
