• Installation, electrical connection, commissioning, operation and maintenance of the
measuring system must only be carried out by trained technical personnel.
The technical personnel must be authorised for the specified activities by the system
operator.
• Technical personnel must have read and understood these Operating Instructions and must
adhere to them.
• Before commissioning the entire measuring point, check all the connections for
correctness. Ensure that electrical cables and hose connections are not damaged.
• Do not operate damaged products and secure them against unintentional
commissioning. Mark the damaged product as being defective.
• Measuring point faults may only be rectified by authorised and specially trained
personnel.
• If faults can not be rectified, the products must be taken out of service and secured against
unintentional commissioning.
• Repairs not described in these Operating Instructions may only be carried out at the
manufacturer’s or by the service organisation.
1.3 Operational safety
The transmitter has been designed and tested according to the state of the art and left the
factory in perfect functioning order.

!Note!
• The device is approved for protection class II and is generally operated without a protective
earth connection.
• To guarantee measuring stability and functional safety, you have to ground the outer screen
of the sensor cable:
– Glass electrodes (PR/PS device version): terminal "S"
– ISFET sensors (IS device version): PE distributor rail
This is on the cover frame for panel-mounted instruments and in the connection
compartment for field devices.
• Ground the PE distributor rail or the ground terminal.
Field instrument connection
Guide the measuring cables through the PG glands into the housing. Connect the measuring
cables in accordance with the terminal assignment (→Fig. 10).

Field instrument measuring cable connection
Proceed as follows to connect a pH-electrode to the field instrument:
1. Open the housing cover to access the terminal block in the connection compartment.
2. Break the punching of a cable gland from the housing, mount a PG gland and guide the
cable through this Pg gland.
3. Connect the cable in accordance with the terminal assignment .
4. Tighten the Pg gland.
"Caution!
Make sure to protect the connectors, cable ends and terminals against moisture as this could
result in incorrect measurement!
Panel-mounted instrument measuring cable connection
To connect a pH electrode to the panel-mounted instrument, connect the cable in accordance
with the terminal assignment to the terminals on the rear of the device.
If you are using glass electrodes with the panel-mounted instrument, you have to terminate the
measuring cable with a BNC connector. A solder-free BNC connector is supplied with the
device.
Proceed as follows:
1. Cut off end sleeves 2 and 3 of the coaxial
cable (Fig. 13).

2. Push the cable gland 5 and the washer 6
onto the coaxial cable.
3. Remove the insulation (13 mm(0.51"))
and screw the clamping ring 7 onto the
insulation.
!Note!
Parts 5 to 7 are supplied with the BNC
connector for cable diameters 3.2 mm
(0.13") and 5 mm (0.20").
4. Fold the braided screen 8 of the screen
over the clamping ring and cut off the
excess material.
5. There is a semi-conductor layer 14
(conductive foil) between the inner
insulation and the braided screen 8. Strip
this semi-conductor layer to the braided
screen.

6. Remove the inner insulation (4 mm
(0.16")).
7. Position end sleeve 13 onto the stripped
inner conductor and secure the end
sleeve with a crimping pliers. C07-OPM223xx-04-06-00-en-015.eps

8. Push the BNC connector housing 9 over
the cable. The inner conductor must be
located at clamping surface 10 of the
connector.
9. Tighten the cable gland 5.
10.Insert the clamp element 11 and screw in
the connector cover 12. This creates a
safe connection between the inner
conductor and the connector pin. C07-OPM223xx-04-06-00-xx-016.eps
