6.1 Electrical connection

6.1.1 Safety notes for electrical connections

WARNING

Electrical connections in hazardous areas

Regulations in the test certificate applicable for your country must be followed.

National regulations and laws for hazardous areas applicable in your country must be

followed for electrical connections. In Germany, these are, e.g.:

• Working reliability regulation

• The regulation for erecting electrical systems in hazardous areas, DIN EN 60079-14

(earlierVDE 0165, T1)

• The EC-type examination certificate

WARNING

If the intrinsically safe version is accidentally operated with a higher operating voltage, the

positioner may not be used in intrinsically safe applications any longer.

When used in areas having potentially explosive atmospheres, electrical auxiliary power

can be supplied to the positioners in flameproof enclosures only if the enclosure is closed

and the approved electronic unit has been installed. If required, we recommend checking

whether the available auxiliary power supply matches with the one specified on the type

plate and in the test certificate applicable for your country.

In case of flameproof enclosures, the duct openings for electronic connections must be

closed with EEx d certified cable inlets or EEx d certified sealing plugs, or, if the conduit

piping system is used, an ignition trap must be provided at a maximum distance of 46 cm

(18") from the enclosure.
