General notes

The devices may only be mounted,started up and operated by experi-enced personnel familiar with this

product.

According to these mounting and operating in-structions, trained personnel is referred to asindividuals who are able to judge the workthey are assigned to and recognize possibledangers due to their specialized training, theirknowledge and experience as well as theirknowledge of the applicable standards.Explosion-protected versions of this device areto be operated only by personnel who has un-dergone special training or instructions or whois authorized to work on explosion-protecteddevices in hazardous areas.Any hazards that could be caused in the valveby the process medium, the signal pressure orby moving parts are to be prevented by meansof the appropriate measures.If inadmissible motions or forces are producedin the pneumatic actuator as a result of the sup-ply pressure level, it must be restricted using asuitable supply pressure reducing station.Proper shipping and appropriate storage of thedevice are assumed.For technical data, ordering data, accessoriesand spare parts see Data Sheet T 3967 EN.

Model number and device index

The model number and the device index areshown on the nameplate:

3967-XXXXXXXXXXXXXXXX XX

�Attachment

Before mounting, all relevant partsof the plant must be depressurized.Due to the high surface resistance,

the device must be mounted and serviced inhazardous areas in such a way that no elec-trostatic charging is to be expected.

The devices can be mounted in any desired po-sition.The cable gland must be installed verticallydownwards or, if this is not possible, horizon-tally (see “Connection cable“, page 11).On mounting, make sure that a minimum clear-ance of 200 mm above the enclosure cover iskept.When the devices are to be used in hazardousareas of zone 21 according to EN 50281-1-1:1998, the equipment must be mounted in anadditional enclosure made of steel, stainlesssteel or plastic. The enclosure including its con-nection parts and bushings must be proven tocomply with degree of protection IP 54 accord-ing to IEC 60529:1989.In locations where there is a risk of mechanicaldamage to the enclosure, the enclosure must befitted with additional protection to fullfill the requirements in paragraph 6 of EN 61241-0:2006 Electrical apparatus for use in the pres-ence of combustible dust.

Air connection

The air supply pipes and screwjoints must only be laid and mount-ed by experienced personnel. They

must be regularly checked for leaks and dam-age, and if necessary, repaired. Before start-ing any repair work, all supply pipes whichare to be opened must be depressurized.

The air connections are tapped holes or the airis connected over the NAMUR interface ac-cording to VDI/VDE 3845.

Electrical connection

For electrical installation, observe the relevantregulations and the accident preventation reg-ulations that apply in the country of use. InGermany, these are the VDE regulations andthe accident preventation regulations of theemployers´ liability insurance.The following regulations apply to installationin hazardous areas: EN 60079-14:1998 (VDE0165-1:1999) Electrical Apparatus forExplosive Gas Atmospheres and EN 50281-1-2(VDE 0165 Part 2/1999) Electrical Apparatusfor Use in the Presence of Combustible Dust.For instrinsically safe electrical equipment ap-proved in accordance with Directive 94/9/EC,the data specified in the EC type examinationcertificate and the statement of conformity ap-ply to the connection of intrinsically safe cir-cuits (see “Certifications“, pages 14 to 22).

Do not loosen enameled screws inor on the enclosure.

Connecting cable

The power supply is connected through a cablegland � to screw terminals � underneath theenclosure cover (see Fig. 13 and 14).

When connected to DC voltage sig-nals, correct polarity must be en-sured.

The cable gland � with an O-ring � under-neath can be installed according to the mount-ing position hanging vertically downwards orhorizontally. The unused cable entry must besealed by a plug � and an O-ring � under-neath.Devices which are used for ambient tempera-tures to �45 °C must be provided with a metalcable gland.It is recommended to use connecting cableswith a conductor cross-section of 0.5 to2.5 mm2 and an external diameter of 5 to8 mm. The diameter of an individual wire in afine-stranded conductor must not be smallerthan 0.1 mm.Protect the conductor ends against splicing,e. g. by using wire-end ferrules.

Degree of protection

The devices are protected against water anddust by a venting plug at the enclosure cover(see “Venting“, page 8).

The required degree of protection IP 65 according to IEC 60529:1989can be only guaranteed with in-

stalled enclosure cover, integrated ventingplug, closed cable entries and proper installa-tion of the connections.

Servicing explosion-protecteddevices

If a part of the device on which the explosionprotection is based needs to be serviced, thedevice must not be put back into operation untila qualified inspector has assessed it accordingto explosion requirements, has issued aninspection certificate or given the device amark of conformity.Inspection by a qualified inspector is not re-quired if the manufacturer performs a routinetest on the device prior to putting it back intooperation. The passing of the routine test mustbe documented by attaching a mark of confor-mity o the device.Replace explosion-protected components onlyby original, routine tested components from themanufacturer.Devices that have already been used outsidehazardous areas and are intended for futureuse inside hazardous areas must comply withthe safety requirements placed on serviced de-vices.The devices must be inspected before being putback into operation as specified in para-graph (6) in Article 14 of the GermanOrdinance concerning the protection of safetyand health at work (BetrSichV).
