General elbow-type plug installation instructions

To mount the connection cable (2-, or 3-wire depending on type of
device) the elbow-type plug screw has to be loosened and the cou-
pling insert has to be removed by means of a screw driver at the
position indicated (arrow).
Pull out connection cable through glanding and connect to the
loose coupling insert as described in the wiring diagram.
Replace loose coupling insert onto the pins at the transmitter hous-
ing and turn cover cap with cable outlet in the direction desired untill
it snaps on (4 different starting positions at 90° intervals).
Re-tighten the screw at the angle plug.

6.3  Usage of Unit-Labels

As the transmitter is a multiple purpose device, many different display units are possi-
ble, e.g. µS/cm, kOhm·cm.
Therefore unit-labels (within scope of supply) can be shoved between the case cover
and the front foil behind the 

transparent unit-window

.

To replace a label, unscrew the cover, pull out the old label (if present) and shove in the
new one.
The unit depends on the settings of the Cell-constant, the function and the measuring range!
Please refer to table in chapter “Configuration of the device”
