6. Mounting
All six versions of the transmitter (Fig. 1) 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. Both methods of mounting and the relevant drilling and cut-out
plans can be seen from Table 1.
Table 1:

Mounting versions

For the example of KINAX 3W2 with standard drive shaft at front only, ∅ 2 mm,
length 6 mm.
Three M3 screws are needed for the "directly" mounted versions and three M4
screws for those "with clamps". The screws 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.
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 fit 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
There are 3 soldering posts (3) on the back of the transmitter for attaching the
electrical connections (see Fig. 4). The soldering posts suffice Protection Class
IP 00 according to EN 60 529.
Fig. 4
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
See "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 installa-
tions in explosion hazard areas must be taken into account!
