3.3 Pre-installation requirements
The required steps are explained in the following sections.
Unpacking the sensor
• Remove by gently twisting and pulling the protective cap from the sensor 1.
• Lay the sensor on a soft ESD mat or soft paper tissue 2.
• Leave the protection cap of the VP connector, as long as the sensor is not connected to the
cable.
CAUTION!
• Do not drop the device! Handle the device with care!
• Never touch or scratch the electrodes of the sensor.
• Store the sensor in its original packaging in a dry, dust-free location. Keep it away from dirt. If
necessary, clean it. See cleaning procedure on page 28
.
•
Do not make any mechanical modifications to the sensor (electrodes shortened, drilled, bent
or scratched). This can result in the loss of proper functionality, as well as the rights under
the device warranty.
• The sensor must be suitable for the temperature, pressure and medium conditions which are
specified (including chemical resistance).
• The device must not be heated by radiated heat (e.g. exposure to the sun) to a electronics
housing surface temperature above the maximum permissible ambient temperature. If it is
necessary to prevent damage from heat sources, a heat protection (e.g. sun shade) has to be
installed.
INFORMATION!
A sensor specific DTM software for usage with PACTware
TM
FDT is available. The DTM software
is free of charge and available from CD (scope of delivery) or can be downloaded from the

4.2 Power supply
The sensor requires a minimum operating voltage of 15 VDC. The power supply is provided via
the 2-wire interface (4...20 mA).
During initialisation of the sensor following values appear in the display mode of the "Measuring
value":
The specification NaN (Not a Number) disappears after a few seconds once the initialisation of
the sensor is completed. Afterwards, the measured values appear.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
DANGER!
All work on the electrical connections may only be carried out with the power disconnected.
DANGER!
Observe the national regulations for electrical installations!
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.

4.3 Grounding and equipotential bonding
Sensor type SMARTPAT COND 7200 must have a capacitive connection to ground.
SJB 200 W-Ex junction box offers the grounding possibility.
For further information refer to the SJB 200 W-Ex manual.
For connection of SMARTPAT sensor use only a VarioPin cable with shield wire, like the
cable VP2-S.
4.4 Connecting the cable to the sensor
Connecting the cable to the sensor
• Ensure that both cable and sensor connector are absolutely dry 1.
• Screw the cable connector 2on the sensor connector and tighten it by hand.
4.5 Connecting the sensor cable
WARNING!
During installation of the device make sure that you use ESD (electrostatic discharge) protection
equipment.
CAUTION!
Moisture on the sensor connector must be avoided! Moisture may cause a short-circuit and a
malfunction of the sensor!
If moisture has entered the connector dry it with air (e.g. hot air gun).
Figure 4-1: Connecting the cable to the sensor
DANGER!
All work on the electrical connections may only be carried out with the power disconnected.
INFORMATION!
The cable glands installed by the manufacturer are designed for a cable diameter of 8 mm...13 mm /
0.31"...0.51". If you are using cables with a larger diameter, you must replace the manufacturer's cable
glands with suitable ones. The operator is responsible for the correct sealing of cable glands.

WARNING!
Ensure that the pipeline is without pressure before installing or removing a sensor!
INFORMATION!
During installation you should fix a shut-off valve in front of and behind the instrument so that
the sensor can be taken out in case of check.
INFORMATION!
To achieve reliable measuring results, the electrodes must always have full contact with the
measuring medium.
INFORMATION!
Basically any installation position is possible. However, ensure that sufficient medium flows
through and around the electrodes (the conductive electrodes must always be completely
surrounded by the medium). Structural measures must be taken to prevent flow interruption or
gas bubbles.
