1.2 Manual conventions
When the wording “Click Start ...” is used, this refers to the Windows® Start button.
Compared to Windows®XP, Windows®Vista, Windows®7 and Windows®10, the Start
Menuhasundergonesomesignicantchanges.Thetaskbariconisnolongerlabeled
“Start” and is now simply the pearl icon (of the window-frame in an orb).
For clarity and convenience, these conventions are used throughout this manual:
●Menu names from the display appear in bold, blue lettering.
●Settings within a menu appear in bold, red lettering.
●Front panel controls and control names appear in bold, black lettering.

2.1 Introduction
Impor
tant
Read this section before using this product!
This instrument is mains powered and protective ground connections are required
(unlessotherwisespeciedforcertainparts).
This manual contains information and warnings that must be observed to keep the
instrument safe. The instrument should not be used when environmental conditions
exceedtheinstrument’sspecications(e.g.damp,highhumidity)oriftheunitisdam-
aged.
For the correct and safe use of this instrument, it is essential that both operating and
service personnel follow generally accepted safety procedures in addition to the safety
precautionsspeciedinthismanual.
Whenever it is likely that safety protection has been impaired, the instrument must be
madeinoperativeandsecuredagainstanyunintendedoperation.Qualiedmainte-
nance or repair personnel should be informed. Safety protection is likely to be impaired
if, for example, the instrument shows visible damage or fails to operate normally.
Appropriate use
This instrument and the connected transducers may be used only for measurement
and directly related control tasks. Any other use is not appropriate. To ensure safe
operation,theinstrumentmayonlybeusedasspeciedinthisusermanual.
●The covers protect the user from live parts and should only be removed by suitably
qualiedpersonnelformaintenanceandrepairpurposes.
●The instrument must not be operated with the covers removed.
●This instrument must not be used in life support roles.
●There are no user serviceable parts inside the instrument.
Itisalsoessentialtofollowtherespectivelegalandsafetyregulationsforspecic
applications during use. The same applies to the use of accessories. Additional safety
precautions must be taken in setups where malfunctions could cause major damage,
loss of data or even personal injury.
Some examples of precautions are: mechanical interlocking, error signaling, limit value
switches, etc.

Maintenance and cleaning
The instrument is a maintenance-free product. However, please note the following
information about cleaning the housing:
●Before cleaning, disconnect the instrument completely.
●Clean the housing with a soft, slightly damp (not wet!) cloth. Never use solvents,
since these could damage the housing or the labeling on the front panel.
●When cleaning, ensure that no liquid gets into the housing or connections.
General dangers, failing to follow the safety instructions
This instrument is a state-of-the-art device and as such is fail-safe. Using this instru-
ment may be hazardous if it has been installed incorrectly and is operated by untrained

Residual risks
This instrument’s scope of supply and performance covers only a small area of mea-
surement technology. In addition, equipment planners, installers and operators should
plan, implement and respond to the safety engineering considerations of measurement
technology in such a way as to minimize any residual risks. Prevailing regulations
must be complied with at all times. The residual risks of the measurement technology
must be referenced.

●Project personnel: Have a working knowledge of the safety concepts of automa-
tion and test and measurement technology.
●Automation plant or test and measurement operating personnel: Have been
instructed on how to handle the equipment and are familiar with the operation of
the cards and technologies described in this documentation.
●Commissioning engineers or service engineers: Have successfully completed the
training on how to repair the automation systems. They are also authorized to acti-
vate, to ground and to label circuits and equipment in accordance with engineering
safety standards. It is essential that the legal and safety requirements for the
product and any accessories are complied with during use.

2.2 Grounding
The instrument must be used with a protective ground connection via the protective
ground conductor of the supply cable. The protective ground conductor is connected
to the instrument before the line and neutral connections are made when the supply
connectionismade.Ifthenalconnectiontothesupplyismadeelsewhere,ensure
that the ground connection is made before line and neutral connections are made.
WARNING
Any interruption of the ground connection, inside or outside the instrument, is likely to make
the instrument dangerous. Intentional interruption is prohibited.
For protection against electric shock, all external circuits or equipment need a safe
insulation. Therefore, peripheral equipment must not be connected to the system with
a power supply without the SELV (Separated Extra Low Voltage) rating unless explicitly
mentioned.
Signal connections to the instrument should be connected after the ground connection
is made and disconnected before the ground connection is removed, i.e. the supply
lead must be connected whenever signal leads are connected.
WARNING
For safety, it is essential that the protective ground connector of the instrument is used
whenever voltages greater than 33V RMS, 46.7V PEAK or 70V DC (IEC 61010-1:2010) are
connected. This is to prevent the instrument’s case becoming live in the event of a protec-
tive ground interruption, which could occur if the supply connector is accidentally discon-
nected from the instrument.
The primary purpose of protective grounding is to provide adequate protection against
electric shock that could cause death or injury to personnel while working on de-en-
ergized equipment. This is accomplished by grounding and bonding to limit the body
contact or exposure to voltages at the work-site to a safe value if the equipment were
to be accidentally energized from any source of hazardous energy. The greatest source
of hazardous energy in most cases is direct energizing of the equipment from a pow-
er-system or source.
WARNING
If connection to a protective ground is not possible for any reason, then please refer to the
international safety standard EN 50191:2000

2.3 Instrument Symbols
A variety of symbols can be found in the system. Below is a list of symbols and their
meaning.
This symbol is used to denote the measurement ground connection.
This point is not a protective ground connection.
This symbol is used to denote a protective ground connection.
This symbol is used to denote a frame or chassis ground connection.
This point is not a protective ground connection.
Where caution is required, this symbol refers to the user manual for
further information.
This symbol warns that high voltages are present close to this symbol.
This symbol shows that the switch is a power switch. When pressed,
the instrument state toggles between the operating and power-off
mode. When the system is in power-off mode, all electronics are dis-
connected from the power, except for a small circuit used to detect the
switch state.
