2.4.4 IECEx Certification
Model EJX Series pressure transmitters with
optional code /SU2 can be selected the type of
protection (IECEx Intrinsically Safe/type n or
flameproof) for use in hazardous locations.
Note 1. For the installation of this transmitter, once a
particular type of protection is selected, any
other type of protection cannot be used. The
installation must be in accordance with the
description about the type of protection in this
instruction manual.
Note 2. In order to avoid confusion, unnecessary
marking is crossed out on the label other
than the selected type of protection when the
transmitter is installed.
