hazardous areas, the general installation conditions for explosion protection EN 60079-14 and
this safety information must be observed.
The requirements of EN 61241-1, in relation to dust accumulation and temperature for example,
must be met.
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 60079-11 and EN 60079-31 for use in hazardous areas with dust.
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.

2.3 Flammable products
Atmospheric conditions:
An explosive atmosphere is a mixture of air and flammable gases, vapours, mists or dusts under
atmospheric conditions. It is defined by the following values
Tatm = -20...+60°C / -4...+140°F and Patm = 0.8...1.1 bar / 11.6...15.9 psi.
Operation outside the specified above standard atmospheric conditions is permitted only via risk
assessment of the user and additional measures, as necessary.
Operating conditions:
Outside of atmospheric conditions, the explosion protection according to directive
2014/34/EU (ATEX) – regardless of the zone assignment – is not applicable due to the lack of key
safety data.

Ignition protection classification:
When it comes to devices with a gas/dust combination approval and two ignition protection
classifications on the nameplate, the device may be used either in gas or in dust. In the case of
devices with an "Ex-t/Ex-ia" combination approval and two ignition protection classifications on
the nameplate, the device may no longer be used as intrinsically safe equipment following non-
intrinsically safe supply.

3.1 Mounting
Mounting and setup must be carried out according to the applicable installation standards
(e.g. EN 60079-14 or IEC 60079-14) by qualified personnel trained in explosion protection.
The information given in the manuals and the supplementary instructions must be observed at
all times.
Install pressure transmitters so that:
•the device is not in a pneumatic flow.
•there is no danger from mechanical impact effects.
CAUTION!
The manufacturer is not liable for any damage resulting from improper use or use other than the
intended purpose. This applies in particular to hazards due to insufficient corrosion resistance
and suitability of the materials in contact with product.

OPTIBAR 5060
www.krohne.com 04/2021 - 4005260702 - AD OPTIBAR 5060 Exta R02 en
4.1 Grounding
The OPTIBAR * 5060 VGK5/6/D*A/W/V R/H/1/7/S/T*******(*)************** must be grounded.
In the case of the version with remote housing of the OPTIBAR * 5060 VGK5/6/D*A/W/V
R/H/1/7/S/T*******(*)************** pressure transmitters, the equipotential bonding must be
provided in the complete mounting area of the connection cable between electronics housing
and transmitter housing.
4.2 Cable entry
The supplied cable entry is suitable for the housing temperature range certified for the
OPTIBAR * 5060 VGK5/6/D*A/W/V R/H/1/7/S/T*******(*)**************-.
Cable entries may only be replaced by the same type or suitable cable glands separately certified
as per ATEX/IECEx with minimum IP 66 must be used.
If a cable entry other than the one provided is used, the separately certified cable entry
determines the maximum permitted ambient temperature at the electronics housing (maximum
values: -40°C / -40°F, +80°C / +176°F).
4.3 Material resistance
The OPTIBAR * 5060 VGK5/6/D*A/W/V R/H/1/7/S/T*******(*)************** should only be used
in media against which the wetted materials are sufficiently resistant.
4.4 Housing cover lock
In the case of the single chamber housing versions the housing cover must be turned until it
stops before starting up and using the OPTIBAR * 5060 VGK5/6/D*A/W/V
R/H/1/7/S/T*******(*)************** in explosive atmospheres. It should be secured using the
lock on the cover.
For the double chamber housing versions the housing cover on the terminal compartment and
the housing cover on the electronics compartment must be turned until they stop before starting
up and using the OPTIBAR * 5060 VGK5/6/D*A/W/V R/H/1/7/S/T*******(*)************** in
explosive atmospheres. They should be secured using the appropriate lock on the cover.
