4.1General instructions
Make sure that all parts of the instrument exposed to the process,in
particular the sensor element,process seal and process fitting,are
suitable for the existing process conditions.These include above all
the process pressure,process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data"or on the
type label.
To protect the diaphragm,the process fitting is covered by a protective
cap.
Remove the protective cap just before installation so that the
diaphragm will not get damaged.It is recommended to keep the cap
and use it again later for storage or transport.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module.The housing can be rotated by 330°without the use of any
tools.You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry.Rain and condensation water can thus drain off.This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g.through cleaning processes)or
on cooled or heated vessels.

Caution:
Due to the filter effect,the pressure compensation is time delayed.
When opening/closing the housing cover quickly,the measured value
can change for a period of approx.5s by up to 15 mbar.
Information:
Make sure that the filter element is always free of buildup during
operation.Ahigh-pressure cleaner may not be used for cleaning.
With instrument versions in protection IP 66/IP 68,1bar,the ventilation
is realised via the capillaries in the permanently connected cable.The
filter element is replaced by a blind stopper.
Higher process temperatures often mean also higher ambient
temperatures.Make sure that the upper temperature limits stated in
chapter "Technical data"for the environment of the electronics housing
and connection cable are not exceeded.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltage surges are expected,overvoltage arresters should
be installed according to Foundation Fieldbus specification
Tip:
We recommend VEGA overvoltage arrester B63-32.
Inhazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
The instrument requires a operating voltage of 9…32 V DC.
Operating voltage and the digital bus signal are carried on the same
two-wire connection cable.Power is supplied via the H1power supply.
Connection is carried out with screened cable according to Fieldbus
specification.
Use cable with round cross-section.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
Make sure that the entire installation is carried out according to the
Fieldbus specification.In particular,make sure that the bus is
terminated with suitable terminating resistors.
On the instrument with cable entry ½NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.
Caution:
Nogrease should be used when screwing the NPT cable gland or
steel tube into the threaded insert.Standard grease can contain
additives that corrode the connection between threaded insert and
housing.This would influence the stability of the connection and the
tightness of the housing.
In systems with potential equalisation,connect the cable screen
directly to ground potential at the power supply unit,in the connection
box and at the sensor.The screen in the sensor must be connected
directly to the internal ground terminal.The ground terminal outside on
the housing must be connected to the potential equalisation (low
impedance).

5Connecting to power supply
36715-EN-110629

Insystems without potential equalisation,connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor,the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen.The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g.1nF,1500 V). Low-
frequency potential equalisation currents are thus suppressed,but the
protective effect against high frequency interference signals remains.
The total capacitance of the cable and of all capacitors must not exceed
10 nFin Ex applications.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equalisation
currents flow over the cable screen.In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove it by
turning it slightly to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm of the cable mantle,strip approx.1cm
insulation from the individual wires
5Insert the cable into the sensor through the cable entry
6Lift the opening levers of the terminals with a screwdriver (see
following illustration)
7Insert the wire ends into the open terminals according to the wiring
plan
8Press down the opening levers of the terminals,you will hear the
terminal spring closing
9Check the hold of the wires in the terminals by lightly pulling on
them
10 Connect the screen to the internal ground terminal,connect the
outer ground terminal to potential equalisation
