Electrical Connections - Camille Bauer KINAX WT707 Betriebsanleitung

When installing or servicing intrinsically safe
(Ex) instruments with enclosure made from
synthetic material, care must be taken to avoid
electrostatic charges.
Make the cut­out or drill the holes in the item onto which the
transmitter is to be mounted according to the correspon­
ding drilling and cut­out 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 cut­out 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 plug­in 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 dan­
gerous!

Also note that, ...
... the data required to carry out the prescribed
measurement must correspond to those marked
on the nameplate of the KINAX WT707 (
measuring input,
power supply)!
... the total loop resistance connected to the
output (receiver plus leads) does not exceed the
maximum permissible value R
ring 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!
7.1 Connecting transmitters with plug­in connector
The plug­in connector (1) consists of a socket (1.1) mounted
on the rear (2) of the transmitter and plug (1.2) on the end
of the connecting cable (screw gland PG 11) and 7 screw
terminals (wire gauges up to max. 1 mm
be mounted so that the cable is routed to either the rear
(Fig. 1, left) or the front (Fig. 1, right).

Remove the screw (1.3) and the connector casing.
Slightly lift the spring latch (1.6) and remove the cover (1.4)
from the body (1.5) of the connector casing.
