5 Protection against static electricity

The IPT-10/11-A/R/4/5-***-**-******C/X-** in the version with chargeable plastic parts, such as e.g.metal housing with inspection window, are provided with a caution label referring to the safetymeasures that must be taken in case electrostatic charging occurs during operation.

Caution: Plastic parts! Danger of static charge!

l Avoid frictionl No dry cleaningl Do not mount in areas with flowing, non-conductive products

6 Use of an overvoltage arrester

On request the IPT-10/11-A/R/4/5-***-**-******C/X-** can be provided with an overvoltage arrester.

If the IPT-10/11-A/R/4/5-***-**-******C/X-** are used as category 1/2G instruments, overvoltageprotection measures according to EN 60079-14 Chapter 12.3 are not required.

When used as category 1G instrument, a suitable overvoltage arrester must be connected inbetween as protection against overvoltages according to EN 60079-14 chapter 12.3.

7 Grounding

In order to avoid the danger of electrostatic charging of the metallic parts, the IPT-10/11-A/R/4/5-***-

**-******C/X-** must be electrostatically connected to the local potential equalisation (transferresistance ≤ 1 MΩ), e.g. via the ground terminal, when used as category 1G or 1/2G instruments.

8 Impact and friction sparks

The IPT-10/11-A/R/4/5-***-**-******C/X-** in aluminium version must be mounted in such a way thatsparks from impact and friction between aluminium and steel (except stainless steel, if the presenceof rust particles can be excluded) cannot occur.

In applications as category 1G or 1/2G instrument, the process pressure transmitters in the titaniumversions must be mounted in such a way that sparks from impact and friction between titanium andany other hard material cannot occur.


38985-EN-121031

9 Material resistance

For applications requiring instruments of category 1G or 1/2G the IPT-10/11-A/R/4/5-***-**-******C/X-

** must only be used in products against which the wetted materials are sufficiently resistant.

10 Mounting with external indicating unit

The intrinsically safe signal circuit between IPT-10/11-A/R/4/5-***-**-******C/X-** and the externalindicating unit should be set up without grounding. The required insulation voltage is > 500 V AC.

When using the provided connection cable, this requirement is fulfilled. If grounding of the cablescreen is required, it must be carried out according to EN 60079-14 paragr. 12.2.2.3.

11 Installation/mounting

The IPT-10/11-A/R/4/5-***-**-******C/X-** have to be mounted in such a way that the sensor unit isadequately protected from touching the vessel wall, taking vessel installations and flow conditionsinto account. This applies especially to sensor lengths over 3 m.
