Authorized use
BVS 16 ATEX E 118 X
3 AUTHORIZED USE
Non-authorized use of the device may be dangerous to
people, nearby equipment and the environment.
▶Thedeviceisdesignedtobemountedonpneumaticlifting
androtaryactuatorsforthecontrolandregulationofmedia.
Type 8791 to 8793 PX45 is approved according to device
groupIIcategory3G/Dforuseinexplosion-riskareasof
Zones2and22.Thecompleteidenticationislocatedonthe
type label (see chapter "5.4").
▶Thedeviceismountedonapneumaticliftingorrotaryactua-
tor. In doing so, the control valve must have at least explosion
protectionapprovaloftheposition/processcontroller.
▶During use observe the permitted data, the operating condi-
tionsandconditionsofusespeciedinthecontractdocu-
ments, the operating instructions and on the type label
-oftheposition/processcontrollerand
- the control valve.
▶Use the device only in conjunction with third-party devices
and components recommended and authorized by Bürkert.
▶Correct transportation, storage and installation as well as care-
fuloperationand maintenanceareessentialfor reliableand
fault-freeoperation.
▶Usethedeviceonlyforitsintendedpurpose.
4 PARTICULAR SAFETY
INSTRUCTIONS
DANGER!
Risk of explosion when removing the electric circular plug.
▶Secure cable connections, which use circular plugs, with
suitablelockingclips.Thiswillpreventthecircularplugfrom
working loose.
Forexample:EXCLIP,FA.PhoenixContact,
TypeSAC-M12-EXCLIP-M,art.no.1558988or
TypeSAC-M12-EXCLIP-F,art.no.1558991
or locking clips, FA. ESCHA
LockingclipM8x1,art.no.8040691
LockingclipM12x1,art.no.8040501.
▶Do not remove or connect electric circular plug until the power
supply has been disconnected.
Risk of explosion when opening the device.
▶Open device only when no explosive atmosphere is present.
Risk of explosion caused by electrostatic discharge.
Intheeventofasuddendischargefromelectrostatically
chargeddevicesorindividuals,thereisariskofexplosionin
the potentially explosive atmosphere.
▶Protectdevicefromlargecharge-generatingprocesses.
▶Groundhousingbeforestart-up.
▶Take suitable measures to ensure that no electrostatic dis-
charges can build up in the potentially explosive atmosphere.
▶Cleanthedevicesurfacebygentlywipingitwithadampor
anti-static cloth only.

Particular safety instructions
BVS 16 ATEX E 118 X
DANGER!
To prevent the risk of explosion, observe not only the safety
instructions in the operating instructions for operation in the
potentially explosive atmosphere, but also the following:
▶Specicationsonthetypelabelconcerningtemperatureclass,
ambienttemperature,degreeofprotectionandvoltage.
▶Do not use device in areas where there is gas or dust with a
lower ignition temperature than indicated on the type label.
▶Installation,operationandmaintenancemaybeperformedby
qualiedtechniciansonly.
▶Observetheapplicablesafetyregulations(alsonationalsafety
regulations)aswellasthegeneralrulesoftechnologyforcon-
struction and operation.
▶Donotrepairthedeviceyourself,butreplaceitwithanequiva-
lentdevice.Repairsmaybeperformedbythemanufacturer
only.
▶Do not expose the device to any mechanical and/or thermal
loads which will exceed the limits described in the operating
instructions.
▶Use only cable and line entry points which have been approved
for the respective application area and which have been
screwed into place according to the associated installation
instructions.
▶Thecableglandsmaybeusedfortheinsertionofpermanently
installed cables and lines only.
▶Close all unnecessary cable glands with lock screws approved
forthepotentiallyexplosiveatmosphere.
▶Use pre-assembled cable glands according to the installa-
tioninstructionssuppliedbytheglandmanufacturer.Before
start-up in the potentially explosive atmosphere, check
whether the cable gland, as described in the associated
installation instructions, has been installed.
4.1 Special conditions of use
▶Do not use the device in dust atmospheres in which inten-
sive charging processes can be expected.
▶Usethedeviceonlyinanareawithatleastdegreeofsoil-
ing2,asdenedinIEC60994-1.
▶Ensure that the transient protection has been set to a value
whichdoesnotexceed140%ofthemeasuredpeakvoltage
valueatthesupplyconnectionsofthedevice.
▶Ifdevicesfeatureacircularplugconnection(multipole),the
mating plug will be provided by the end user and is not an
objectoftheapproval.Thematingplugmustsatisfythe
relevantrequirementsoftheIEC60079-0,IEC60079-7and
IEC60079-31andmusthaveatleasthousingdegreeof
protection IP65 according to IEC 60529.
▶Ifdevicesfeatureacircularplugconnection(multipole),use
aspeciallockingclipwhichpreventstheplugfrombeing
loosened without a tool.
