If the intrinsically safe version is operated with a higher operating vol-
tage by mistake, the positioner must no longer be used for intrinsically
safe application.
The explosion-proof positioner may only be supplied with electrical
power in areas in which the atmosphere may be potentially explosive
when the housing is closed. Where power supply is required, we
recommend checking the power supply to ensure that it corresponds
with that on the name plate and with the test certification valid for your
country.
The feed-though openings in the explosion-proof version for the
electronic connections must be sealed with EEX-d certified cable
glands or EEx-d certified plugs or an ignition lock must be mounted at
a maximum distance of 46 cm (18 inches) when using the “conduit”-
system.
The plastic housing is metal lined to increase the electromagnetic
compatibility (EMC) against high frequency radiation. This screen is
connected electrically to the threaded bushes shown in figure 3-12,
page 58.
Please bear in mind that this protection can only be effective if you con-
nect at least one of these bushes with grounded fittings by electrically
conductive (blank) mounting parts.
