1.1 General notes
These safety instructions are valid for the pressure transmitter OPTIBAR * 5060
VGK5/6/D*A/W/V E/Z/6/7 with integrated electronics Z (4…20 mA), H (4…20 mA/HART), A
(4…20 mA/HART® with SIL qualification), P (Profibus PA), F (Foundation Fieldbus), S, T
(electronic differential pressure measurement) without additional electronics (X) and OPTIBAR *
5060 VGK5/6/D*A/W/V E/Z/6/7 with integrated electronics H (4…20 mA/HART) or A (4…20
mA/HART® with SIL qualification) with additional electronics (Z) according to the EU type
examination certificate TUEV 17 ATEX 208187 X.
The pressure-based measuring devices OPTIBAR * 5060 VGK5/6/D*A/W/V E/Z/6/7 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 * 5060 VGK5/6/D*A/W/V E/Z/6/7 consist of an "Ex-db"-electronics housing with
integrated electronics module, 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 mounted.
The OPTIBAR * 5060 VGK5/6/D*A/W/V E/Z/6/7 are suitable for use in hazardous atmospheres of
all combustible materials of explosion group IIA, IIB and IIC for applications requiring equipment
category 1/2G or 2G.
When the OPTIBAR * 5060 VGK5/6/D*A/W/V E/Z/6/7 are installed and operated in hazardous
areas, the general Ex installation regulations EN 60079-14 as well as these safety instructions
must be observed.
1.2 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 60079-1, EN 60079-11 and EN 60079-26 for use in hazardous areas with gas.
The EU type test certificate forms the basis of the EU declaration of conformity:
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.

1.3 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 60079-1, 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.
1.4 Safety instructions
Assembly, installation, start-up and maintenance may only be performed by personnel trained in
explosion protection!
IECEx TUN 18.0007 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.
