1.1 General notes
These safety instructions are valid for the differential pressure transmitter
OPTIBAR DP 7060 VGK7*A/W/V C/H/0 with integrated electronics type Z (4…20 mA),
H (4…20 mA/HART®), A (4…20 mA/HART® with SIL qualification), P (Profibus PA) or F
(Foundation Fieldbus), with additional electronics (Z) according to the EU type examination
certificate BVS 15 ATEX E 047 X.
The differential pressure-based measuring devices OPTIBAR DP 7060 VGK7*A/W/V C/H/0 are
also used for pressure and level measurement in hazardous areas.
The measured products can also be combustible liquids, gases, mist or vapours.
The OPTIBAR DP 7060 VGK7*A/W/V C/H/0 consist of an electronics housing with integrated
electronic insert, a process connection element and a probe, the pressure measuring cell with
optionally connected diaphragm seal. As an option, the display and adjustment module can also
be integrated.
The OPTIBAR DP 7060 C VGK7*A/W/V C/H/0 are suitable for use in hazardous atmospheres of all
combustible materials of explosion group IIA, IIB and IIC for applications requiring equipment
category 1G, 1/2G or 2G.
If the OPTIBAR DP 7060 VGK7*A/W/V C/H/0 are installed and operated in hazardous areas, the
general installation conditions for explosion protection EN 60079-14 and these safety
instructions must be observed.
1.2 Different ignition protection types
The differential pressure transmitter of the OPTIBAR 7060 series can be either used in explosive
dust atmospheres or in explosive gas atmospheres.
The operator must specify the selected ignition protection type before installation. The selected
ignition protection must be marked firmly on the identification label of the name plate.
If the OPTIBAR DP 7060 VGK7 A/W/V H is installed in a dust atmosphere, then the safety
instructions and the instructions in the respective certificates must be noted.
1.3 EU conformity
The manufacturer declares with the EU declaration of conformity on his own responsibility
conformity with the protection goals of directive 2014/34/EU according to EN/IEC 60079-0,
EN 60079-11 and IEC 60079-26 for use in hazardous areas with gas.
The EU declaration of conformity is based on the EU type examination certificate:
The "X" after the certificate number refers to special conditions for safe use of the device, which
have been listed in these instructions.
If needed the EU type examination certificate can be downloaded from the manufacturer's
website.

1.4 Approval according to the IECEx scheme
Conformity with IECEx standards was tested in accordance with the "IECEx Certification Scheme
for Explosive Atmospheres" according to IEC 60079-0, IEC 60079-11 and IEC 60079-26. The
number of the IEC certificate is:
The "X" after the certificate number refers to special conditions for safe use of the device, which
have been listed in these instructions.
If needed the IEC certificate can be downloaded from the manufacturer's website.
1.5 Safety instructions
Assembly, installation, start-up and maintenance may only be performed by personnel trained in
explosion protection!
IECEx BVS 15.0036 X
CAUTION!
The operator or his agent is responsible for observing any additional standards, directives or
laws if required due to operating conditions or place of installation.
