5 Protection against static electricity

The VEGABAR BR5*/6*.C… in versions with electrostatically chargeable plastic parts, such as e.g.plastic housing,metal housing with inspection window, with plastic coated sensors, suspension cableor suspension hose, distance tube or connection cable with the separated version, a caution labelpoints out the safety measures that must be taken with regard to electrostatic charges duringoperation.

Caution: Plastic parts! Danger of static charge!

l Avoid frictionl No dry cleaningl Do not mount in areas close to flowing, non-conductive media

6 Use of an overvoltage arrester



If necessary, the VEGABAR BR5*/6*.C… can be connected to an overvoltage arrester, e. g. typeB62-36G from VEGA.


28190-EN-081114

If the VEGABAR BR5*/6*.C… are used as category 1/2G instruments, overvoltage protectionmeasures according to EN 60079-14 sect. 12.3 are not required.

When used as category 1G instrument, a suitable overvoltage arrester, e. g. type B62-36G fromVEGA (TÜV 07 ATEX 553276) must be connected according to EN 60079-14 chapter 12.3, forprotection against voltage surges.



If necessary, the VEGABAR BR5*/6*.C… can be connected to an overvoltage arrester, e. g. typeB62-30W from VEGA.

If the VEGABAR BR5*/6*.C… are used as category 1/2G instruments, overvoltage protectionmeasures according to EN 60079-14 sect. 12.3 are not required.

When used as category 1G instrument, a suitable overvoltage arrester, e. g. type B62-30W fromVEGA (TÜV 07 ATEX 553276) must be connected according to EN 60079-14 chapter 12.3, forprotection against voltage surges.

7 Grounding

In order to avoid the danger of electrostatic charging of the metallic parts, the VEGABAR BR5*/6*.

C…must be electrostatically connected to the local potential equalisation (transfer resistance ≤ 1MΩ)

e. g. via the ground terminal when used as category 1G respectively 1/2G instrument.

8 Impact and friction sparks

When used as category 1G or 1/2G instruments, the VEGABAR BR5*/6*.C… in aluminium/titaniumversions must be mounted in such a way that sparks from impact and friction between aluminium/

titanium and steel (except stainless steel, if the presence of rust particles can be excluded) cannotoccur.

9 Material resistance

For applications requiring instruments of category 1G or 1/2G the VEGABAR BR5*/6*.C… must onlybe used in products against which the wetted materials are sufficiently resistant.

10 Mounting with external indicating unit VEGADIS 61

The intrinsically safe signal circuit between VEGABAR BR5*/6*.C… and the external indicating unitVEGADIS 61 should be installed without grounding. The required insulation voltage is > 500 V AC.

When using VEGA connection cable, this requirement is fulfilled. If it is necessary to ground the cablescreen, this must be carried out according to EN 60079-14 paragr. 12.2.2.3.

11 Installation/mounting

The VEGABAR BR5*/6*.C… have to be mounted such that they are effectively secured against thedanger by touching the sensor on the vessel wall under consideration of the vessel installations andflow conditions in the vessel. Especially suspension pressure transmitters and versions with distancetube lengths of more than 3 m are concerned.
