Electrical Connections - Gossen MetraWatt KINAX WT 710 Mode D'emploi

Pay attention when aligning and tightening the
transmitter that the electrical zero and the zero of
the item being measured coincide.
To permit any adjustment of the electrical zero that
may be necessary to match the zero of the measured
object, we recommend also elongating the three 3.2
mm diameter mounting holes (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

The transmitter is equipped with screw terminals and two
cable glands for the electrical connections.
Make sure that the cables are not live when
making the connections!
The 230 V power supply is potentially
dangerous
Also note that, ...
... the data required to carry out the prescribed
measurement must correspond to those marked
on the nameplate (Fig. 6) of the KINAX WT 710
(measuring input,
power supply)!
... 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 rouled 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 EC-type-
examination certificate, the EN 60 79-14 and also
local regulations applicable to electrical installations
in explosion hazard areas must be taken into
account!

7.1 Connecting transmitters
There are 4 screw terminals (2.1) and 1 ground terminal (2.2)
in the casing (1). The screw terminals are suitable for wire
gauges up to 1.5 mm2 and are accessible when the cover is
removed.

Take off the plastic cover.
Undo the gland nut and remove the pinch ring and seal from
the gland opening. Place these parts over the cable in the
correct order and pass the end of the cable through the gland
hole into the housing of the transmitter.
Strip the insulation from a suitable length of the leads and
connect them to the terminals (2.1) and ground terminal (2.2)
according to the respecive wiring diagram (Fig.8 or 9).
Then fit the gland seal, pinch ring and nut. Tighten the gland
nut and replace the cover.
