2.9.4 IECExCertication
Model EJX Series pressure transmitters with
optional code /SU2 can be selected the type of
protection (IECEx Intrinsically Safe/type n or
ameproof)foruseinhazardouslocations.
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.
a. IECEx Intrinsically Safe Type / type n
Caution for IECEx Intrinsically safe and type n.
Note 1. Model EJX Series differential, gauge,
and absolute pressure transmitters with
optional code /SU2 are applicable for use
in hazardous locations
