Safety notes for electrical connections
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
• The EC-type examination certificate
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.
Assembling the components
When assembling components, ensure that only those positioners and optional modules
are combined with each other that are approved for the corresponding operating range.
This condition is particularly applicable for the safe operation of the positioner in the areas
of zones 1, 2 and 22, where the atmosphere may be potentially explosive. Observe device
categories 2 and 3 of the device itself and its optional modules implicitly.
CAUTION
The following is applicable for all intrinsically safe versions of zones 2 and 22:
The cable used for electrical connections must be suitable for temperatures that are 5°C
higher than the ambient temperature.
