3 INSTALLATION
3.1 Installation
Installation 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:
• there is sufficient overvoltage protection in the event of lightning or overvoltage.
• they are not in a pneumatic flow.
• excessive dust deposits (over 5 mm) and complete dust coverage are prevented.
• there is no danger from mechanical impact effects.
• the device is accessible for any necessary visual inspections and can be viewed from all sides.
• the nameplate is clearly visible.
• it can be operated from a location with secure footing.
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.

4.1 Protection against static electricity
The OPTIBAR * 5060 VGK5/6/D*A/W E/Z/6/7 in versions with electrostatically chargeable plastic
parts, such as e.g. plastic housing, metal housing with inspection window, with plastic-coated
sensors, suspension cable or suspension hose, distance tube or connection cable with the
remote version, a caution label points out the safety measures that must be taken with regard to
electrostatic charges during operation.
Caution: Plastic part! Risk of electrostatic charge!
• Avoid friction
• No dry cleaning
• Do not mount in areas with flowing, non-conductive products
FURTHER NOTES 4
4.2 Use of an overvoltage arrester
If necessary, a suitable overvoltage arrester can be connected in front of the OPTIBAR * 5060
VGK5/6/D*A/W E/Z/6/7. When used as category 1/2G equipment, as far as necessary analogue, a
suitable overvoltage arrester must be connected in front as protection against voltage surges
according to EN 60079-14 or IEC 60079-14 Chapter 12.3.
4.3 Grounding
In order to avoid the danger of electrostatic charging of the metallic parts, the OPTIBAR * 5060
VGK5/6/D*A/W E/Z/6/7, used as category 1/2G equipment, must be electrostatically connected to
the local equipotential bonding (transfer resistance ≤ 1MΩ), e.g. via the ground terminal.
4.4 Impact and friction sparks
When used as category 1/2G equipment, the OPTIBAR * 5060 VGK5/6/D*A/W E/Z/6/7 in light alloy
(aluminium/titanium) versions must be mounted in such a way that sparks from impact and
friction between light alloy and steel (except stainless steel, if the presence of rust particles can
be excluded) cannot occur.
4.5 Material resistance
With applications requiring 1/2G equipment, the OPTIBAR * 5060 VGK5/6/D*A/W E/Z/6/7 should
only be used in media against which the wetted materials are sufficiently resistant.
4.6 Installation / mounting
The OPTIBAR * 5060 VGK5/6/D*A/W E/Z/6/7 have to be mounted such that the sensor is
effectively secured against touching the vessel wall, under consideration of other vessel
installations and flow conditions in the vessel. This applies especially to suspension pressure
transmitters and versions with distance tube lengths over 3 m.

4 FURTHER NOTES
4.7 Protection type flameproof enclosure Ex "d"
The terminals for connecting to the operating voltage, i.e. signal circuits, are integrated in the
terminal compartment according to protection type flameproof enclosure "d".
The gaps between housing and cover as well as between threaded fitting and container are
ignition-proof gaps.
The "Ex-d" terminal compartment has an M20 x 1.5 or 1/2-14 NPT thread for the connection of a
certified "conduit" system or for the installation of an "Ex-d" cable entry certified according to
EN 60079-1 or IEC 60079-1. Simple cable entries should not be used. Refer to sections 13.1 and
13.2 of EN 60079-1 or IEC 60079-1. When connecting to a "conduit" system, an appropriate
sealing mechanism must be located directly on the "Ex-d" terminal compartment.
The factory may supply a certified "Ex-d" cable entry. Depending on the type ordered, it may be
suitable for sheathed or unsheathed cable types. The document supplied with the corresponding
cable entry must be observed. The "Ex-d" cable entry must be permanently screwed into the
housing. The supplied cable entry is suitable for the housing temperature range certified for the
OPTIBAR * 5060 VGK5/6/D*A/W E/Z/6/7. If a cable entry other than the one supplied is used, the
other certified cable entry or the temperature classes of the electronics, depending on the
permissible temperature, determines the maximum permitted ambient temperature of the
housing.
OPTIBAR 5060
The screw plug (blind plug) supplied by the factory, depending on the type ordered, is part of the
"Ex-d" housing. If a screw plug other than the one supplied is used, it must be certified according
to EN 60079-1 or IEC 60079-1.
Ensure that before opening the "Ex-d" terminal compartment and when the cover of the
compartment is open (e. g. when connecting or servicing) the supply line is de-energised or that
there is no explosive atmosphere present.
The connecting cable to the "Ex-d" terminal compartment must be fixed and laid so that it is
sufficiently protected against damage. Lay the connecting cable in accordance with EN 60079-14
or IEC 60079-14.
The connecting cables, cable entries and screw plugs or pipeline sealing mechanisms must be
suitable for the lowest ambient temperature.
Prior to start-up, ensure that the cover of the "Ex-d" terminal compartment is screwed in all the
way until it stops. Secure it by unscrewing the locking screw of the cover until it stops.
Unused openings must be sealed according to EN 60079-1 or IEC 60079-1 paragraph 11.9.
The cover of the "Ex-d" terminal compartment has the warning label "Do not open when an
explosive gas atmosphere is present".
